It is not only solid recyclable waste that can be repurposed to re-enter the market; organic waste can also follow a circular economic approach to add value to the economy as well as to the environment. BiobiN South Africa explains why composting is the more financially feasible solution to deal with organic waste, compared to landfilling.

Increasing demand for agricultural organics: Organic waste can easily be integrated into a circular economy with many advantages. A key advantage is the growing demand for agricultural organics, especially compost. The opportunity of converting organic waste into highly fertile compost is being tapped into by many commercial and industrial facilities in South Africa.

Keeping solid recyclables clean: A big driver to adopt a circular model for organic waste is to prevent the municipal solid waste stream from contamination, impacting what can then be recycled. In most cases, solid waste that is mixed with organic waste needs to be separated and cleaned before it is recycled. This significantly adds to the costs of recycling certain materials along their value chain. Separating the organic waste stream on-site where it is generated prevents the cost of having to clean and sort a mixed waste stream, and increases the quality of dry, uncontaminated recyclable waste. Recent trials have shown that due to a reduction in contaminated waste, general waste reduces by up to 30 % and recyclable volume increases by up to 30%.

Gaining carbon tax credits: With any financial management plan, tax features as a significant aspect and with organic waste, it is no different. According to South Africa’s carbon tax regulations, organic waste management technology is eligible to register as a carbon credit project, which presents a strong business case to operate an organic waste management business. Our carbon tax places the responsibility on ‘carbon emitters’ to pay for the volumes of carbon emissions that their activities produce. Carbon emitters can look for carbon credit projects to buy carbon credits to reduce their carbon tax liability.

A major market Rand value: According to recent research, the Western Cape generated 533 745 tonnes of municipal organic waste in 2019, and 326 945 tonnes of commercial organic waste. If these volumes were to be economically recycled, they would have a market value of up to R162 million.

Landfill is a costly solution: In the Western Cape alone, sending organic waste to landfill sites cost the commercial and industrial sector approximately R138 million in disposal costs for 2019. Landfilling waste can be a costly exercise; from needing a waste licence, maintaining waste inventory reports, transportation, processing and final disposal, there are costs associated with every stage.

The sensible solution: On-site composting is rapidly becoming the preferred waste management solution to deal with commercial and industrial organic waste. BiobiN’s units are specifically designed according to a facility’s waste management requirements.

BiobiN® is a clean and simple solution to managing organic and wet waste that would otherwise end up in landfill. It provides large scale composting units based on a unique and innovative design which will safely remove hazardous and odorous elements from organic waste material, whilst recycling the waste into a safe, environmentally friendly and rich organic compost. The patented aeration system initiates the composting process of organic material, reducing odours, bacteria and other pathogens, and is the most efficient and effective method for managing food and organic waste.
