Hydrocarbon Pollution Remediation Project


A study was carried out on a Remediation Demonstration (the Demo) in November-December 2017 at Nsisioken, Ogale, Eleme Local Government Area (LGA), as part of capacity assurance processes of the Hydrocarbon Pollution Restoration Project (HYPREP) set up under the Federal Ministry of Environment (FME) by the Federal Government of Nigeria (FGN) to deliver recommendations of the United Nations Environment Programme (UNEP) assessment report in 2011 which proposed a holistic restoration of impacted soils and water in Ogoni Land

Executive Summary

The study carried out the remediation treatment and restoration of the hydrocarbon contaminated land allotted to it by HYPREP using our bioremediation technology. Biotech Clear bioremediation technology involves application of bio-stimulation product a nutrient compound that elicits massive growth of endogenous microorganisms (bacteria and fungi) to degrade/mineralise hydrocarbon in the soil to water, carbon dioxide and biomass (humus). The technology / product is applicable in situ and ex situ treatment to both soil and water at regulated concentration of the nutrient base and the operation process entails (i) site characterisation, (ii) excavation in the case of ex situ application, (iii) treatment, (iv) sampling and (v) laboratory analysis.
Ex situ remediation process was applied for the Demo due to the peculiarity of the Demo Site – premised on extensive pre-treatment site-specific soil and water investigations and tests (including site recharacterization), carried out to determine the site specific geological conditions and hydrogeological / geochemical framework of the subsurface. The treatment (application of our bio-stimulation product to the contaminated soil) was planned for 4 weeks. However, the Demo execution application of product was wrapped up after 3 weeks of treatment of the contaminated soil due to the very high success rate achieved (treated soil field-wide average 95.6% TPH decrease) at 3 weeks.
As part of our post-project execution After Action Review (AAR) process and in line with an overall 90-day follow-up plan for the Demo, we carried out 21-day field observation visit of the Demo Site (on 06/01/2018). Observation showed after treatment restored soil with sprouting plant growth

In further demonstrating the capacity and effectiveness of the application of our product, MicroMix, to hydrocarbon contaminated water, We treated 200 litres of the hydrocarbon contaminated water that percolated in excavated pit (of the soil ex situ treatment) with the product, MicroMix. Result of the 21th-day post-treatment samples taken showed 99.8% reduction in TPH and complete eradication of BTEX.

Purpose & Location of the Remediation Demo

Purpose of the Demo

Objective of the Demo is to demonstrate our expertise and capacity to treat and restore an identified hydrocarbon contaminated land (as allotted by HYPREP) and, using our technology, to substantially decrease the Total Petroleum Hydrocarbons (TPH) of the contaminated soil to a permissible level.

Problem Definition

In 2005, NNPC pipeline ruptured at Nsisioken at Ogale causing spill of refined petroleum (kerosene, gasoline and diesel). The spill “occurred close to the area of housing some meters uphill from the wetland and ground water was contaminated to at least 600 meters from the source of the spill.”

The Demo Site

The portion of land for the Demo (Demo Site) allotted to us by HYPREP, measuring 150m2, is a relatively dry portion adjacent to a swamp surrounding located in Nsisioken, Ogale, Eleme Local Government Area of Rivers State. The Demo site lies west of NNPC product pipelines right-of-way on coordinates: P1: E292747 N529505, P2: E292738 N529512, P3: E292728 N529501, P4: E292736 N529494.

Figure-7A, B & 1C: Remediation Demo Site Location Area & Surrounding

The Demo Location Background

Eleme is one of the 23 LGAs that makes up Rivers State as well as one of the four major clans that makes up Ogoni Land. Ogale is one of the ten major villages making up Eleme. The exact location of our Demo Site is at Nsisioken-Agbi at Ogale. The land is partly adjacent and partly within a local revered land which the community referred to as “sacred forest”. A number of houses have been built close-by on the other side of the pipeline, the closest compound near the Demo Site being approximately 15 meters from the pipeline way.

History has it that the land was uninhabited for decades until the 70s when the swampy part was used predominantly for purpose of commercial catfish farming – as the natives do not eat “fish from the sacred forest water”. There was also subsistence farming where cassava, yam and cocoyam were cultivated. These activities were reported as “flourishing” until the land became contaminated with hydrocarbon

Bioremediation Prionciple Application & Pre-Treatment Field Investigations

The choice of the applicable bioremediation principle and deployment of the appropriate bioremediation technology at the Demo Site requires a re-characterization of the site to determine site-specific geological conditions which may have changed from the data presented in the UNEP (2011) report due to geological dynamics. This necessitated carrying out extensive pre-remediation treatment: field investigations/tests of the hydrogeological and geochemical framework of the subsurface with emphasis on site-specific hydrogeology.

Bioremediation / Biodegradation

Bioremediation is a technology based on the science of biodegradation. In biodegradation, the biochemical versatility of microbes is demonstrated; this is then translated into the bioremediation technology by manipulating nutritional and ecological parameters to suit the microbes. Bioremediation principle can be either biostimulation or bioaugmentation. We applied the bioremediation principle of biostimulation or bioenhancement. This involves enhancing and modification of ecosystem and ecological parameters that would lead to attenuation of pollutants in the impacted media which could be soil, water or air. The enhancement could be addition of nutrient mixes; modifications could be fracturing of soil formations followed by tilling, turning and moisturizing. The tilling and turning enhance oxygen supply to the soil through natural air drafts. The nutrient mixes combine with the oxygen to boost the indigenous population of microbes, which then metabolize the pollutant (petroleum products) to release CO2 + H2O plus more biomass. This is mineralization where organic pollutant is converted to inorganic/mineral carbon (CO2).

Pollutant + MicroMix + O2 + Moisture + Temp + Microbes (stressed in low numbers) > CO2 + H2O + Heat + Biomass (microbes)

Determination of Bioactivity Potential (Biopotential)

Bioactivity potential or biopotential involves the demonstration of the presence of microbes in such impacted media as soil and water. Bioremediation technology is dependent on the ability and capacity of microbes and other biological agents to biotransform pollutants (chemicals of concern) in impacted media into innocuous products. The biopotential was determined using the culture-based total viable aerobic heterotrophic bacterial count in soil and water samples obtained from the Demo site.

Enumeration and Isolation / Identification of the Demo Site Indigenous Bacteria

Two groups of bacteria – total heterotrophic bacteria (THB) and the hydrocarbon-utilizing bacteria (HUB) – were demonstrated in the soil and water samples from the demo site. Enumeration was done on Nutrient Agar plates and Mineral Salts Agar for the THB and HUB (Table-1). Aseptic streaks of MicroMix on sterile nutrient agar plates yielded no observable growth after at least 48 hours of incubation at ambient temperature. Identification of bacterial isolates was done using cell morphological characteristics as well as biochemical properties (Table-2). A total of 29 isolates was observed; these fell into 19 different genera. Both the soil and shallow water at the demo site have a high load of heterotrophic and hydrocarbon utilizing bacteria suitable for bioremediation of the impacted media.

The impacted soil was excavated to a 6m depth using a light weight excavator, suitable for bioremediation of the impacted media. The soils obtained were at 1m intervals and spread out to approximately 25cm depth and treated with the product, MicroMix. This depth is amenable to more readily movement of air which is needed for aerobic metabolism of the pollutant by microbes and the spreading also enhances attenuation of pollutants by volatilization. With respect to water, 200 liters of the hydrocarbon contaminated water that percolated in the excavated pit was collected and treated with our products.

Field Studies – Soil & Water Investigations & Tests Generally, the site re-characterization focused on:

  • Checking the rates of changes in the soil contaminants,
  • Quantifying the presence of contaminants in the soil,
  • Matching the site characteristics with the feasibility of the intended in-situ remediation method.

To achieve the above, and as imperative, the subsurface hydrogeological and geochemical framework were mapped with emphasis on the local and site-specific hydrogeology. This is achieved through field and laboratory studies involving electrical resistivity surveys and borehole drilling.

Two geological methods were used to obtain information on the electrical resistivity profile of the subsurface and the textural parameters of the soils necessary for initiation and propagation of injection materials in the subsurface: (i) geophysical investigation & borehole drilling; (ii) sampling and testing of soil & water samples.



Using Schlumberger array for 1-d survey and Werner array for 2-d survey, electrical resistivity surveys were performed at site in the first instance – to provide an image of the underground resistivity and get a model of the distribution of rock types (clays, sandstones, etc.) in the underground, to determine the depth of a specific target horizon: e.g. groundwater level, groundwater quality and presence of contaminants.



Hydrogeological & Geochemical Survey

Four borehole drillings were carried out onsite to verify the information obtained from the electrical resistivity survey and to obtain the parameters for the remediation method – including:

  • Depth to local drinking water aquifers
  • Distribution of grain-size (sand versus silt versus clay)
  • Lithology, Site stratigraphy – including identification of transmissive and non-transmissive units
  • Aquifer hydraulic conductivity determination and estimates from grain-size distributions
  • Ground-water hydraulic information preferential flow paths
  • Local ground-water recharge/discharge area

Reports: Investigations/Tests Outcome Resistivity Profile

Result of hydrogeological survey conducted to study lateral variations in the resistivity of the soil, corroborating laboratory analysis, indicated that the assigned Demo Site has hydrocarbon contamination to depth of 7 metres.

Figure-12: Hydrocarbon Impacted Soils (shown as blue colour at top of the figure)

Note: The impacted soil in the middle is outside the demonstration location.



Hydrology Framework

The four boreholes were drilled to different depths (4m, 5m, 6m and 10m) to establish the lithologic log and distribution of the soils. Summary of assessment indicated dark silty-clayey sand at the top soil, silty-clayey sand up to 7m depth and medium to coarse sand up to 10m depth.

Pre-Work Execution Site Inspections

After the extensive pre-work investigations of the Demo site, to determine and proactively prepare for the management of foreseeable operational and HSE challenges, we further conducted a series of pre- work execution site inspections and consultations (with HYPREP, NNPC, Community representatives and security operatives) – including visit to residence which (as noted in the UNEP report of some residents that claimed to smell oil in their drinking water) confirmed the presence of oil sheen and kerosene smell in water collected from tap connected to the residential bore hole.

The most-notable HSE and operational challenges encountered, respectively, were (i) the closeness of the site to and the attendant risk of crossing live petroleum products pipelines with heavy moving equipment machinery on a marshy/swampy terrain and (ii) the poor permeability due to high clay content of the Demo Site soil. Key results of the pre-work site inspections and management of the challenges are discussed below.

NNPC Pipeline

NNPC product pipelines run underground from Port Harcourt refinery to UmuNwaNwa through Nsisioken-Agbi where the Demo site is located. These affected the nature and route (entry/exit) of Heavy Moving Equipment (HME) required for site operation. In view of the identified HSE implications, we carried out pipeline probing, using underground cable/pipe locator, by which the exact pipeline location was obtained which shows that the Demo Site is situated approximately 10m away from the NNPC trunk lines located along KP 5.805 to KP 6.788 which transports refined products (gasoline, diesel and kerosene).

Shell Pipeline

The NNPC product pipelines cross a number of other pipelines downstream at Nsisioken-Agbi, including the SPDC 28-inch Rumuekpe - Bomu trunk line and the 36-inch Nkpoku - New Ebubu (Ogale) trunk line. This poses further HSE risk factor / challenge affecting the HME route to the site location.

Road Location

Due to above challenges, only one safe route to the Demo Site location was eventually found after thorough consultations and assessment. However, that road itself posed yet another challenge: it was operationally impassable as the HME (excavator) could not be deployed onsite due to the road condition. This led to us expending sums to make the route operationally passable for HME mobilisation and demobilisation.

Demo Site & Work Execution Overview - Site Physical Layout

The Demo site work area was designated into three zones as required ex situ bioremediation treatment of contaminated land:.

The Hot Zone had a perimeter fencing with a walkway which leads to as well as separates the Decontamination Area and the Staging Area. The erected perimeter fence significantly reduced potential exposure of people living near the site to contaminants and, because of its oleophilic and hydrophobic nature, helped to wick up any run off oil and prevent flooding of the work area.

The Decontamination Area is the measure for decontamination to ensure the health & safety of personnel which was managed per decontamination procedure that was developed and applied. The Decontamination Area was identified using barrier tapes and the corridor was lined with sorbent roll to reduce slippage and absorb oil. The point of entry from the Hot Zone into the Warm Zone and the exit corridor into the Cold Zone were established, identified and clearly marked. A primary and secondary decontamination wash and rinse (wading pools) were established and all personnel were given adequate briefing on the decontamination procedures before entering the Hot Zone.

Sorbents were laid within inner perimeter of the soil treatment area to further prevent run off to adjourning land or other parts of the site and daily checks were performed to monitor that these controls and the fence remained in good condition. Special attention was taken during and after periods of rain and during high wind.

Ex Situ Remediation

Six areas (of 25m2 each) were delineated and prepared for treatment of contaminated soil. Each area was

  • Covered with a liner laid underneath and made to form a protective fence around the perimeter of the spread-out soil to prevent run off and leaching.
  • Separated by and placed inbetween the treatment areas to further prevent run off.



The impacted soil excavated at depths of 0-1m, 1-2m, 2-3m, 3- 4m, 4-5m and 5- 6m respectively were spread on the liners at the delineated portion for each depth to 25cm thickness to maintain aerobic condition of the soil. Signs and caution tapes were used to barricade the trench and each treatment area had the soil depth clearly displayed.

The concentration of MicroMix used for the ex situ treatment of excavated soil was calculated based on the established TPH baseline values at various depths. The first application was carried out on 27th November 2017. This was immediately followed by tilling to ensure aeration and product penetration. Oxygen enrichment of the soil was enhanced by continuous daily tilling of the soil for the first 7 days of application and subsequently every other day. To keep the soil humid, being clayey in nature particularly from depths 2 to 6m, daily irrigation was carried out by a sprinkling system using watering cans. The moisturizing of the soil was maintained at an optimal condition by applying visual observations to prevent run off.

Sampling of the soil and water for TPH and BTEX (Benzene, Toluene, Ethyl Benzene and Xylene) analysis were done prior to commencement of application of MicroMix and subsequently at 7 days, 14 days and 21 days post treatment.

Quality Assurance & Control

In line with our Quality Policy QA/QC, that “the integrity of samples collected determines the quality of the result obtained”, the following key quality management performance guaranteed sample integrity and ensured quality:

  • Use of validly calibrated tools
  • Use of DPR / FME accredited laboratories
  • Pre-execution inspection/audit of designated laboratories
  • Collection of sample in sterile package and labeled immediately
  • Cleaning of sampling tools before sampling to avoid cross contamination
  • Storage of sample at the appropriate temperature for transfer to laboratory
  • Deployment and application of site-specific operational processes
  • Submission of Chain of Custody and analysis request with samples to laboratory (signed by both parties)

Health Safety & Environment (HSE)

In line with our HSE Policy, HSE was duly managed upfront - including development, deployment and implementation of the Demo site specific HSE Plan, thus achieving our Goal Zero HSE Policy Aspiration. Summary HSE key performance and challenges covering the Demo execution ifollows:

Sample from Key/Remarkable HIRs, the Step(s) Taken and Outcome:
  • Insufficient nose mask at site hot zone – risk of hydrocarbon inhalation: fit for purpose (organic vapour) nose masks acquired and deployed.
  • Inadequate hard barrier for excavated ditch – risk of fall into hydrocarbon contaminated ditch: risk discussed at TBM and requisite control (hard barriers around the open ditch as well as a hazard tag) put in place.
  • Contractor came to site with inadequate HSE-critical equipment (discharge hose not available) risk of release of contaminated water: STOP WORK was applied – contractor job suspended until requisite equipment was provided.

Will use technology combined with state of the art irrigation systems and basic machinery to not only clean the oil from the soil and water but will complete the process by the planting indigenous grasses, crops, fruit trees, forests... We will continue irrigation for a few weeks until the plants/trees are stable. Going from oil saturated land to green, food producing land or forests will help to fight climate change.

With the HYPREP project's footprint expanded, We will implement emerging technology such as the floppy sprinkler system to provide required moisture. Oxygenation would be created through rototillers or tractors for the land and the delivery of nanobubbles for aquifers.

We are capable of treating millions of cubic meters of hydrocarbon contaminated soil/water. Our product is well suited for large scale remediation projects. We only need to know the size of the land requiring remediation, then our engineers can deliver the rest.

Remember, our product is nontoxic and can be used on aquifers, fish and mangroves for an immediate result. The only byproducts are CO2, O2 and humus with an additional benefit of a decrease in the mosquito population.

We are capable of treating hundreds of acres in parallel as demonstrated. In locations where the waterways need remediation, we would simultaneously set up two permanent booming structures: one for trash (logs, etc.) and one to direct the oil to a skimming/collection area; and even add an oil sorbent fencing that collects the oil in water flowing up 3 knots while letting the water flow through.

The Sprinkler is a unique and innovative sprinkler based on cutting edge technology and has been patented in 11 countries. Its origin lies in the successful creation of an unconventional emitter. At the core of the sprinkler’s success is its flow controller which ensures a very accurate flow of water through the Sprinkler.

The sprinkler is made entirely from plastic and silicone and has no moving parts and thus requires no or minimal maintenance.

  • 90% application efficiency
  • 44% less water
  • Up to 43% energy saving

Security & Community Affairs

Security and community affairs considerations were also duly managed upfront - including development and deployment of the Demo Specific Security Plan and Community Management thus resulting in Achieving Zero Significant Security Incident & Zero Significant Community Infractions during the entire period of the demo execution.

A detailed Risk Assessment was conducted at the site and environs and the identified threats and potential sources of peril were duly addressed:

  • Community inundated with hydrocarbon product & crude pipe lines which drawsattentionofcriminalelementsthatbreakopenfacilitiestosiphon products
  • Significant JTF (Military Joint Task Force) presence as a result
  • Area considered in security circle as containing bastions of militancy & cult related activities
  • Youth unemployment at an all-time high
  • Ass general in the Niger Delta, Companies bear immense financial pressure due to high expectations caused by oil firms who had operated in the area and in the Niger delta generally
   Very High   

Principally, amongst other strategies and tactics, we employed a threefold measure to manage the threats.

  1. Capturing the hearts and minds of the community, especially the community critical leaders–lead by the King of Ogale with able support of the Chiefs and the Community Youth Leaders – through the effective liaison with and intervention of the designated HYPREP CLO. It is worthy to note here that the HYPREP CLO and Community Leaders demonstrated during the Demo execution that they, indeed are in-charge and on top of their game in managing the community matters and duly discharged the duty of acting as buffer, bastion and security against threat sources.
  2. Reservation and absolving a sizeable number (16 nos.) of the community members as field operations support workers and civilian security guards / information gathering resource. Also, in line with this strategy, some of the visibly influential community personalities were deliberately co-opted into the site operations matters on the tactics of “give a major and aggressive stakeholder a role to play and you have duly reduced your problem therefrom”. We ensures that items required which could be sourced within the community are provided by members of the community – hence other community leaders and members were given roles like hiring of site furniture, clearance of site, provisions of tents/shelter and messing facility, etc.
  3. Deployment of armed security personnel t make a ignificant presence at the site and as a deterrent for would be non-conforming or criminal-minded elements that may be within the Community or environs. To this end, a contingent of the crack JTF troops stationed in the vicinity of the Demo site were engaged to provide the needed security cover on terms that were mutually beneficial to both parties. The JTF were duly briefed of our mission and the nature of activities and supported our Site operations under Rules of Engagement in line with our Security Policy Strategy. The JTF personnel were requested to institute constant patrols and post a significant presence at the site which they effectively carried out and which ensured the protection of site equipment, especially the excavator and other items, during the demo execution.
We Can Do Much More

What More Can BioTech Clear Bio-Stimulation Technology & Products, Do?

UNEP indeed puts it right - that the Niger Delta Restoration solution should be holistic.

In line with our innovative green technology values & vision and our Policy, from a health perspective, is genuinely concerned of the effect of continued exposure for the people (workers and interfacing personnel and community members) in the course of this long-term project of Ogoni Land Restoration. Furthermore, in the same vein and looking at the potable water situation in Nigeria, We are not a believer in chlorine and other substances that are not good for the health. Our biostimulation technology and products can do more – in light of providing and the application of holistic approach.

Cleaning the Waters Naturally & Control Vector Disease – the 1-2-3 Punch Project.

Using BioTech Clear's other green technological products and processes, we can clean the waters naturally. We call this the 1-2-3 Punch Project.

  1. Collection of water in small villages by using water hippo products and/or some form of water storage tanks (in line with and taking advantage of our scalable resources (see below Capacities/Areas of Business) can be built/manufactured in Nigeria using recycled plastics).
  2. Application to remove all hydrocarbons (as demonstrated in this Demo) as well as eliminate Mosquitoes and other diseases spreading vector species.
  3. Deployment of Madidrop to get rid of all waterborne pathogens through the use of silver ions.

The process is relatively easy and effective and the biproducts are non-harmful. In addition, with our innovative drive, we will develop a home bottle for which, certainly, will create an additional stream of jobs in the Niger Delta region.

Immediate Reduction of Surface Hydrocarbons

Driving innovative spirit further, it can be extended to use for immediate reduction of surface Hydrocarbons anywhere. For example, through surface application even by air to immediately get rid of all surface Benzenes and Hydrocarbons as well as decrease mosquitoes within the environment.

From Oil Saturated Land to Green Producing Land

BioTech Clear's technology combined with state of the art irrigation system and basic machinery in addition to cleaning out the oil will enhance the planting of indigenous grass, fruit trees, economic trees, agriculture or even forests. All that is required is continued irrigation for an assessed period until the plants/trees are stable – hence applied as a way going from oil saturated land to food and green producing land or forest and to fight/reduce the effects climate change.

No matter the size of land, we have the capacity to apply its technology and resources – e.g. by deploying through a sprinkler system (to deliver our solution and water for moisture) and the use of rototillers and/or tractors (to create oxygenation for the land) and nanobubbles for aquifers.

Remember our product, Micromix, is nontoxic and can be used on any media – land, water or air – as well as eco friendly – on aquifers, fish and mangroves – and the biproducts are natural / non-harmful – CO2, 02, humus and in addition the elimination of mosquitoes through starvation at the larva phase.
BioTech Clear's Further Capacities / Areas of Business

Spill Response & Recovery – Cutting-Edge Best Practice Response / Recovery & Training

Our oil/chemical spill response and clean-up/recovery uses skilled responders. To this end, we are bringing

  • Highly experienced international teams, specialized in training and field remediation work with 25+ years of on-the-job experience. Through years of work, they have created the perfect platform for BioTech Clear's “Train the Trainers” program.
  • Hazwoper Tiers 1 to 3 oil spill recovery equipment and cutting-edge products for offshore and shoreline containment which will be deployed to attain best-practices as well as improve/preserve the environment.

After 12-36 months initial period, it is our goal to use only indigenous BioTech Clear trained and certified workers to maintain a minimum >90% of the our team.

Manufacturing, Production and Job Creation

Working in indigenous areas, instead of importing its products, is employing locals and incorporating current technology to create high quality oil spill control and response products needed in Nigeria. We manufactured products include loose absorbent, absorbent pads, socks and booms, containment booms, spill kits, oil snares and sweeps, ...

Training – Environmental, Safety, Health & Response Capacity Development

With our MS, environmental safety and health training is incorporated in our processes Oil Spill Response Training is required of every responder. Response training courses, which we give internally as well as offer to public for capacity development, are aimed at producing sufficient personnel for Response management and the Incident Command Structure.

CSR: Community Social Responsibility – Voluntary Community & Environmental Commitment

Voluntary commitment to sustainable development and improving social status of the community where we operate – along with the use of green products by which we aim to leave each site environment better than it originally was. We promise to give back >5% of its profit to benefit the local communities (to improve the social status) of the area where it operates.

As a Common humanitarian value, a division of BioTech Clear addresses the needs of indigenous people as well as that of the environment such that will create real change in areas like a source of potable water, healthcare, establishment of oil-free fisheries, provision for low cost briquettes, Vector species removal (NO-Skito), etc.


The micro-organisms found in BioTech Clear's NO-Skito have appropriate enzymes, and multiply rapidly feeding off the same substances which the larvae need to feed. In a brief time, food for the larvae is drastically reduced by the micro-nutrients that are transformed in excessive dimensions and unable to be utilized as food by the said larvae. (Larvae starve to death).

Water Hippo

Hippo Roller works with rural and impoverished communities to help improve access to water. Our innovation makes more water and time available for education, household tasks and food production, enabling people to transport up to 5 x more water to their homes and food gardens


The MadiDrop is a porous ceramic disc that has been infused with silver or copper. When dropped in water, the tablet releases ionic silver or copper that strips away bacteria and pathogens to produce clean, drinkable water. Each tablet is capable of treating 10 to 20 litres of water for up to six months


Penetrates all hydrocarbon structures through balanced biotechnology Converts all hydrocarbons into the lowest form of organic compounds where they become food for the natural environment on Sea water - Fresh Water and Land Eliminates hydrocarbon Odor and ToxicityComplete and effective bioremediation when required where it happens. No genetic Modification

LifeCycle ManagementTM – Ancillary Economic Activities Adding Value

BioTech Clear deploys a carefully constructed clean-up/recovery and remediation plan that is based on emerging and historic technologies and designed to maximize clean- up/recovery and remediation benefits for the greater good of the Community including:

  • Restore farmland and purify water
  • Provide solution to remediate existing spills
  • Create atmosphere for other economic growth activities
  • Reclaim oil for feed stock and electricity production

Our cellulose-based, nontoxic, hydrophobic, oleophilic sorbent for oil clean-up technology removes oil from water with an adsorption rate of 30:1; feed stock from compressed sorbent or Pyrolysis, using Thermal Recovery Unit (TRU), can create profit generation through production of biofuel or electricity; and used cellulose can be manufactured into "logs" for local use – for cooking or to sell.

Restoration of Fisheries & Agriculture – Saving Land & Species from Oil Spill Toxins

As hydrocarbon spills toxins and increases stress to the environment and the invasive species take over, fish die from lack of oxygen and the land becomes non-farmable. We addressed these situations with emerging technologies for innovative remediation and restoration that allows water to pass but not the hydrocarbons.

Invasive Species Management – Making Invasive Species Productive

Nypa Palm and water hyacinth are invasive aquatic plants considered as an environmental nuisance in the Niger Delta that interferes with fishing and waterway traffic. Water hyacinth can yield about 322.2 tons biomass per hectare annually – capable of feeding 140 cattle or 9,000 goats or generating 0.1 MW of electricity.

3-year projection for managing this invasive species to be productive

  • Utilizes water hyacinth as feed stock for biogas production
  • Utilizes water hyacinth as feed stock for animals and fish
  • Donations to indigenous people for weaving, art or other uses
  • Fortify anaerobic digesters slurry for bioremediation formula
  • Fortify anaerobic digesters slurry for bio-fertilizer production
  • Create an exportable agriculture top soil
  • Survey, characterize & map Niger-Delta water hyacinth hotspots
  • Convert to an ethanol Biogas and create briquettes for cooking

The application of the BioTech Clear technology and product for the remediation of the hydrocarbon contaminated land allotted Demo Site at Nsisioken, Ogale succeeded tremendously – achieving a field-wide depths of 1 to 6 meters average TPH degradation of 95.6% at 3 weeks of treatment. This confirms our capacity to treat and restore hydrocarbon pollution contaminated sites and effectiveness of our technology and products.

UNEP report and Laboratory analysis shows that BTEX concentration in ground water was 900 times above standard. In order to further demonstrate the capacity and the effectiveness of application of our technology and product to hydrocarbon contaminated water, We collected 200 litres that percolated in excavated pit (for the soil ex situ treatment) and applied the product to treat the hydrocarbon contaminated water. After days the water TPH had degradation of 99.76%. Sample was taken at 40 days of treatment (on 06/01/18). The water sample has been sent to Laboratory for analysis. Sample taking and analysis will be repeated for day 90 (on 25/02/18).

This report in the main covers the demonstration of the application and effectiveness of our bioremediation technology and product, Micromix, to treat and restore hydrocarbon pollution contaminated sites. We have also taken time to demonstrate further benefits that can be derived from and vast uses of the product in the areas of environmental management as well as the further capacity of our organisation.
