"Having worked with big businesses in the agricultural and retail sector, we have to work according to a waste management strategy," says Brian Küsel, director of BiobiN South Africa, which provides on-site composting vessels for corporates to process food and organic waste streams and establish waste information capture systems to record the volumes of organic waste that is diverted from landfill and processed into a secondary resource.
"Along with waste management compliance, there are usually two objectives of a waste management strategy, firstly to reduce the generation of non-recyclable waste, and secondly to create value from waste streams where possible. Therefore your waste management strategy should include targets for waste reduction, and targets for waste recycling and repurposing,” he continues.
Here Küsel provides three steps to meet your waste management targets:
The first step in drafting any waste management strategy is to fully understand a company’s waste situation. This is done through a waste situational analysis. This study will determine the different waste streams that you generate and the associated volumes. It will also determine what streams can be recycled, repurposed on-site, or processed into a secondary resource.
“As an example, your waste reporting may include volumes of waste landfilled, volumes of plastic recycled, volume of hazardous waste generated, volumes of food waste processed into compost, or volumes of waste used as a secondary product,” says Küsel. “This all depends on the waste situation analysis and identifying the available resources in order to extract value out of your different waste streams.”
For most big companies, a centralised waste management facility and drop-off site works well to separate waste at source. A typical on-site waste management facility will include a material recovery facility (MRF) to extract recyclables, hazardous waste storage units, landfill waste separation, and organic waste processing plants. “Given the landfill legislation for organic waste and other mechanisms like the Voluntary Food Waste Agreement, we are seeing more companies use on-site composting vessels to process food and organic waste,” says Küsel.
“Whether or not a company has a centralised waste management facility, mobilising waste management resources and technology is crucial for the implementation of your strategy. Composting units, effluent treatment systems and hazardous waste disposal bins should be available throughout the site, or set up in a way that collects all the waste from each of these streams. This may also involve having to train staff on using on-site waste infrastructure,” he adds.
Once all the waste infrastructure has been established and staff trained effectively, it is important to look at your full waste value chain. Who will be taking your solid waste recyclables and repurposed material? Who will benefit the most? “With more organic waste being diverted from landfill and processed as compost, there is a big need for local and regional composting businesses to take on this secondary resource. This is a big economic opportunity,” says Küsel.
While your waste management strategy should include provisions for meeting your waste reduction recycling and diversion targets, supporting local waste management service providers, especially recycling companies and composting businesses, should also feature as an integral enterprise development initiative.
