The efforts of the Federal Government at cleaning up and remediation of Ogoniland devastated by oil spill has received an additional boost, as the Minister of Environment, Surveyor Suleiman Hassan Zarma is currently leading other senior government officials to the United Kingdom on an international working visit, facilitated by the United Nation Environment Programme UNEP to appraise themselves of international experiences and best practices relative to the clean-up of large-scale contaminated sites.
The United Nations Environment Programme (UNEP) assessed the extent and severity of the contamination in 2011 and found severe and widespread contamination due to oil production spanning several decades. The Federal Government of Nigeria has committed to follow the United Nations Environment Programme’s recommendations. Thus upon assumption of office in 2015, President Muhammadu Bunari underscored his resolve to restore livelihood in the oil-contaminated Ogoniland, by creating the Hydrocarbon Pollution Remediation Project (HYPREP), a dedicated institution to manage the clean-up process under the oversight of the Federal Ministry of Environment.
It is in order to equip them better to deliver on their mandate that the Minister is leading members of HYPREP’s Governing Council as well as other senior stakeholders currently on working visits to five sites in the United Kingdom , as part of a series of International site visits. These include Biogénie’s Trecatti and Redhill soil treatment
Biogénie’s Trecatti contaminated soil treatment facility in Merthyr Tydfil in South Wales is able to clean-up a variety of contaminants with a specific focus on soils impacted by petroleum hydrocarbons. In addition, the Biogénie’s Redhill soil treatment facility in South East England operates at a larger scale and can accept a wider range of types of waste. It also acts as the main treatment facility for London and the South East.
Biogénie’s facilities treat soil which would otherwise be disposed of as hazardous waste. The cleaned-up soil is re-used for restoration and landscaping, demonstrating how a treatment facility can operate as a regional hub to accept hydrocarbon-impacted soils from a number of sites. The Redhill facility also shows how decontamination processes used at other sites can be scaled up.
In addition, the visit will be an opportunity for the delegation to visit Coed Darcy, one of the largest regeneration projects in the United Kingdom. It was formerly occupied by the BP Llandarcy Oil Refinery until operations ceased in the mid-80s. St. Modwen is currently working with Atkins to clean up and redevelop the site in a sustainable way. By 2027, this redeveloped site will be transformed into a new £1.2 billion urban village that will house around 10,000 people.
With a legacy of coal mining, iron works, and chemical works, Chesterfield’s former Avenue Coking Works in the East Midlands is widely regarded as one of the most heavily contaminated industrial sites in Europe. This site offers an opportunity for HYPREP’s Governing Council to witness land that was redeveloped. Around three-quarters of the site were restored for open space, community and ecological uses, with the remainder being used for residential and commercial development.
The international site visit will allow the delegates to observe an extensive range of in-situ and ex-situ remediation techniques, such as soil washing, bioremediation, thermal desorption, and separating techniques, among others. It is envisaged that these demonstrations and visits will build HYPREP’s capacity to reuse and recycle as much site-won material as possible, contributing to the sustainability of the clean-up exercise.
Finally, ALS operates one of the largest laboratories in Europe. The visit to their Chester laboratory in North West England will focus on quality, accreditation, sample preparation, analysis of petroleum hydrocarbons, reporting, and interpretation of analysis. Delegates will have the opportunity to tour this modern laboratory facility and identify the aspects that
