South Africa has a newly revised national waste management strategy that has ambitious goals and waste reduction targets; one being to divert more organic waste away from landfill.
The strategy recognises that organic waste represents the largest single waste type volume in South Africa, and potentially a significant resource.
This highlights the need to implement waste practices and technology that coverts organic waste into an economically valuable resource. BiobiN is a solution that perfectly fits in with this requirement, processing organic waste onsite to produce high-grade compost.
‘Every five years our national waste management strategy is revised and with the Department of Environmental Affairs’ regulation that bans the dumping of liquid or waste with more than 40 per cent moisture content to landfill,’ says Brian Küsel from BiobiN, ‘it is important to look at how the industry has evolved, what waste management challenges still persist and what new technology is working well in other countries that we can bring to South Africa. We have introduced BiobiN to South Africa to tackle the issue of high volumes of organic waste that go to landfill.’
The BiobiN unit has been designed to process all types of organic waste including food scraps, fruit and vegetables, ground coffee, meat scraps, seafood shells, shredded paper and tissues, hair and garden scrap
State of Waste
Released along with the revised national strategy, the latest State of Waste report 2018 indicates that South Africa generates a total of 55.6 million tonnes of general waste of which 62.5 per cent still goes to landfill, a large portion of which is organic waste. It is also estimated from national waste information studies that 10.8 per cent, equating to 2.5 million tonnes, of the general municipal waste stream is food waste.
Food waste continues to burden South Africa’s landfill sites. Through the decomposition of organic waste, including food waste, odorous atmospherics compounds are produced which can be detected up to five kilometres away from the site. Residents living in close proximity to a landfill site have been quick to complain about the poor odour and rodents that are present around the landfill site. With these environmental and health concerns, the South African government has tightened landfill regulations, specifically regulating the volumes of organic waste that goes to landfill.
‘Our BiobiN unit has been designed to process all types of organic waste including food scraps, fruit and vegetables, ground coffee, meat scraps, seafood shells, shredded paper and tissues, hair and garden scrap,’ says Küsel. ‘We introduced BiobiN as we realised that there is a big need to avoid sending this organic waste to landfill.’
‘The unit is designed for convenience, to be odourless and to prevent rodents from entering the area, allowing facilities to reduce their environmental footprint through effective organic waste management,’ says Küsel.
