This type of waste is most abundant but should be reduced in the future as it makes recovery and reuse the most difficult. This can be processed in a dirty Material Recovery Facility but produces considerable unusable residues that are best suited for thermal processing to energy.

Some communities separate recyclables into special bags (coloured or clear). This can be taken to clean Material Recovery Facility for separation into reusable recyclables.

With source separation and many industrial clients there is a large amount of organic waste that is landfilled. This can be composted or used in a biogas process. The biogas process also produces an organic fertiliser that can substitute or add to a compost product.

Residual wastes are left over after most of the recyclables are removed. These wastes typically are too intermingled or contaminated and need to be utilised for thermal energy production or will be landfilled. Sometimes we process this waste stream further to remove contaminants such as ceramics and sand before processing in an incineration plant.

“Very early on in my career as a clinician I was frustrated by the fact that I could only make a difference one patient at a time. The treatment offered did not significantly alter the socio-economic determinants of illness that presented in my practice. My passion for impacting the mental health and well being has led me to investments that are focused on social impact and sustainability. At the Mina Foundation we manufacture and distribute menstrual cups to menstruators primarily of school going age. Our goal is to not only to end period poverty in South Africa and beyond our borders, to keep girls in school and to have a positive impact on the environment..”

“Waste Mart has always been a keen supporter of alternative waste management technologies and techniques to reduce the disposal of waste to landfill, which is both costly and environmentally damaging. When my late father, Mustapha Marthinus started the company over 4 decades ago, South Africa was a very different place, and over the years we have grown and thrived with the positive change in our country. We now see this legacy being handed over to us to drive this change for our children and their children's children. Waste to energy is a key component of this change.”

“Our mission is focused on reducing and on treating the World waste; whether it be municipal waste, all none toxic streams of wastes or treating water. We concentrate on bankable & proven modular technology which our tech providers are roll out quicker than the norm, which norm can be relocated at ease. The equipments we commercialise are robust enough to last the test of time, simple to run. In doing so we are able to bring affortdable Power to those whom secure enough waste and of course Fresh Water for those whom need it the most - Our Vision is to bring lasting and commercially viable solutions to those whom engage with us.”
