The Vissershok Waste Management Facility is a privately owned hazardous waste landfill site, located to the north of Cape Town in South Africa. The joint owners are South African waste management companies, Enviroserv Waste Management and The Wasteman Group (partly owned by Suez Environment). Forty hectares of the site is permitted to receive H:H (high hazard rating) waste and has been in operation since 1974. It has an anticipated life to between 2020 and 2025. The facility presently receives about 300 000t of waste per annum of which some 23 percent is hazardous. The site provides disposal and treatment facilities for many types of hazardous waste. In addition there is an encapsulation process for wastes that cannot be treated or disposed of onto the landfill.
Pilot-scale biological treatability trials have been completed successfully, on representative leachate from a large South African hazardous waste landfill site at Vissershok, near to the city of Cape Town. The leachate is strong and methanogenic in nature, with COD values of about 10,000 mg/l, and concentrations of ammoniacal-N in the range of 2000 to 2500mg/l. Treatment used an SBR system, in a pilot reactor with a capacity of 3200 litres, with a membrane filtration phase used after the biological stage to remove solids to a very low level. A final reverse osmosis stage of treatment achieved removal of dissolved solids, as required to allow treated leachate to be discharged into a local watercourse. This paper describes the trials in detail, and provides full operating results, including detailed analytical results and operating experiences.

Die innerstaatliche Umsetzung des Pariser Klimaschutzübereinkommens
- ein Rechtsvergleich

Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
