Sustainable cost reductions: biogas from liquid wastes
Generate energy instead of consuming it: treating liquid wastes and wastewater on a communal basis to generate biogas is an interesting alternative to conventional wastewater treatment and disposal for dairies. This is becoming a serious consideration for the future for milk producers given the globally increasing challenges arising from wastewater regulations or CO2 guidelines.
More and more dairies are now facing a problem: how to dispose of their liquid waste products. Spreading slurry is not a realistic option any more for the agricultural industry due to the problems of overfertilisation or hygiene. The challenge for dairies is that their liquid waste products generally have a very high organic load. Wastewater accumulates, typically, as a result of cleaning and rinsing processes in production. Local rural treatment plants where most dairies are located are not designed to cope with such high organic loading. In many countries across the globe, milk processors are not even connected to public-sector treatment plants.
Across the globe, dairies therefore have to treat their wastewater themselves or pretreat it before they are allowed to introduce it into the public sewerage system. “This is usually done in aerobic biological plants which requires an oxygen supply,” says Dennis Wiedenhaus, Project Director at EnviroChemie: “That’s expensive and consumes a great deal of energy.”
