Case Study 008 Solving Solvent Recycling

The Western Cape Industrial Symbiosis Programme (WISP) facilitated a one-off exchange where Dekro Paints recycled 4 tonnes of expired solvents from Protea Chemicals. This diverted hazardous waste from landfills, reduced carbon emissions by 19.4 tonnes of CO2e, and saved Protea Chemicals R135,000 in testing, transportation, and landfill fees.

• The collaboration resulted in the diversion of 4 tonnes of expired solvents from hazardous landfills, which led to a reduction in the use of virgin materials and a saving of 19.4 tonnes in carbon dioxide equivalent (CO2e).
• Protea Chemicals achieved significant economic savings through the partnership, including R127,000 in testing and characterisation costs and R8,000 in transportation costs and landfill gate fees.
• Dekro Paints utilized its solvent recycling plant to process 18 drums (approximately 4,000 L) of dirty solvents using filtration, decanting, and distillation to achieve a purity level higher than 99%.
