Organic waste has always been a considerable challenge. Whether separated or as part of mixed waste, it causes contamination and noxious odours. Most organic waste today still ends up in a landfill. Subsequently, decomposition produces leachate which can cause severe land and especially water pollution. It also causes emission of polluting gases, notably methane, into the atmosphere. Separating organics from mixed waste remains one of the biggest challenges for municipal and commercial waste operators.
Anaerobic digestion (AD) and composting plants successfully process pure organic waste. The digestion process produces biogas which is mostly methane. These plants, however, require large quantities of pure organic waste due to the high capital costs. In addition, they process only pure organics and cannot cope with mixed waste.
Companies use various technologies to try and separate organics when processing mixed waste. These come at a cost and as a result treatment plants tend to be large scale and are located far away from waste sources. Consequently, waste transportation is needed over long distances adding to the already high operating costs.
Downscaling Organic Waste Processing
In recent years, many companies have been exploring smaller local solutions for waste treatment. Small-scale anaerobic digestion is one such option to treat organic waste at source. However, this technology is very expensive for such a scale. Furthermore, the digestion process still leaves a considerable proportion of incoming waste as output. This is called digestate which still requires disposal. In some cases, it can be spread on land as fertiliser. However, if it originates from food waste then usually authorities do not allow such use.
How Envitech Can Help
For processing a large volume of organic waste, we can assist with developing anaerobic digestion (biogas) plants. We have extensive expertise and you can find out more on our Biogas Production page. For smaller scale, we have an innovative solution to process organic waste at source. It can eliminate up to 96% of any organic waste within 3 days and is much more cost effective than many other alternatives.
