In Sysav’s pre-treatment plant, food waste is converted into slurry; a pumpable, viscous liquid which is the plant’s end product. The slurry is thereafter tansformed into two useful resources – biogas and bio-fertilizer.
The biogas can be used to fuel vehicles, while the bio-fertilizer replaces chemically manufactured fertilizers in agriculture.
Sysav receives waste from households and businesses in southern Skåne, Sweden’s southernmost province. A combination of methods ensures that the waste is used as a resource in a safe, environmental-friendly and sustainable way.
In addition to biological treatment, these methods include energy recovery from incineration, re-use and various forms of recycling, management of hazardous waste and landfill.
