Through the process of combining biodegradable materials, a new fuel was created that produced electricity and other self-sufficient solutions. This not only saved money, but also reduced environmental impacts by making our waste once again useful.
Known as Anaerobic Digestion, we saw a reduction in fossil fuel by 50% as we discovered what materials would help us make the most of this new process. According to GTS Maintenance, high calorific value plants – such as maize and rapemeal – made for the most effective waste. Other waste was also found to be useful, including manure and slurry, which reduces the impact our waste has on landfill sites – an effective solution for agricultural farmers.
However, further to the reduction in fossil fuel, as stated by Andrew Whiting and Adisa Azapagic,they also reported that, although Anaerobic Digestion seemed to have a positive effect on Global warming potential, there were other aspects that proved negative.
In addition to a simple solution to waste removal, the added financial benefits to farmers; from government incentives to the reduction in energy bills proved enticing. While the materials left over from Anaerobic Digestion have been used as fertilizers for agricultural properties, there were additional costs involved in the transfer from property to property. In response to this, Wavalue created an eco-innovation that combined the excess materials from Anaerobic Digestion with other organic fertilizers and waste resulting in a balanced NPK value. This was then used to create ecofertiliser granules instead of transporting the waste in its pure form. This further reduced “CO2 equivalent emissions” by 50%.
The Wavalue Product, who are co-funded by the Eco-innovation Initiative of the European Union – among other affiliations, were successful in adding substantial value to an already valuable process. Stating that the “new fertilizers will be more ecologically friendly, as they will replace mineral fertilizers with nutrients that come from organic waste.” Their work is more than welcome in an ever-growing, greener planet.
