Kwasi Badu-Tweneboah and Samir Ahmed Lead Landfill Closure in Ghana, West Africa

Kwasi Badu-Tweneboah, Ph.D., P.E., D.GE, and Samir Ahmed, P.E. (Florida) lead the design for a municipal solid waste (MSW) landfill closure in Ghana, West Africa.

Kwasi Badu-Tweneboah has more than 30 years of consulting and research experience focusing on the design, permitting, construction, operation, and closure of containment systems for solid, hazardous and radiological wastes, sediments, and surface impoundments; and geosynthetics applications in civil engineering.

Samir Ahmed has more than 5 years of consulting experience focused on the design, permitting, construction, operation, and closure of containment systems for solid waste.

The closure project of the Kpone Landfill is under a design-build construction contract with Zoomlion Ghana Ltd (Zoomlion), one of the largest waste-management companies in Africa. The project is set to improve overall environmental infrastructure in Ghana. The Kpone Landfill is 33-acres located in coastal Tema, a metropolitan district in the Greater Accra Region of Ghana.

Zoomlion is working towards a sustainable plan for Africa. For the closures of these landfills, Zoomlion chose ClosureTurf®, a geosynthetic cover system created by Watershed Geosynthetics LLC (Watershed Geo), that typically reduce maintenance activities by more than 90%. ClosureTurf®'s three-layered soil-geosynthetic-turf system is comprised of structured geomembrane; nonwoven geotextile with high-density polyethylene a(HDPE) grass blades (i.e., engineered turf); and sand infill ballast.

Geosyntec's involvement in this closure project provides international partnership with waste management and consulting firms in Ghana, which aim to improve the management of solid waste in Ghana and to provide better environmental and sustainable infrastructure for both industries and citizens. In support of the landfill closure design, Geosyntec prepared a closure design report with design calculations, technical specifications, and other support documents (i.e., design drawings, stormwater and gas management design plans, and CQA plan) required to demonstrate the effectiveness of the ClosureTurf® system and also to meet the regulatory requirements in Ghana. Following preparation of the closure design documents, Geosyntec representatives traveled to Ghana to provide training and technical support during closure construction activities. There, Geosyntec observed waste regrading activities; inspected landfill gas extraction equipment; and performed site visits to additional landfill and waste processing facilities in Ghana, resulting in a series of recommendations to improve the performance of the operations at these sites.
