Although expired or uneaten food may look like scraps and manure like a pile of waste, BIOFerm™ views these organics as a source of renewable energy. Our company believes anaerobically digesting organic matter—like manure, wasted food, biosolids, lawn clippings, and more—helps create a more sustainable operation in a variety of ways:
Creates clean energy
The continuous amounts of organic waste produced from farms, food operations, wastewater treatment plants, municipalities, and more offers immense potential for generating renewable biogas. By switching to biogas as a source of electricity, heat, and vehicle fuel, we can dramatically reduce an operation’s carbon footprint. Although burning any type of gas produces emissions, biogas is significantly cleaner than burning coal.
Not only does anaerobic digestion create energy from the biogas generated during fermentation, but the solid and liquid digestate remaining at the end of the digestion process can be turned into sellable, sustainable byproducts. For example, the liquid digestate can be land applied as fertilizer, and the solid digestate can be further processed into high-quality animal bedding, or compost, etc.
“Food waste is the single largest type of waste entering our landfills,” with the USA generating over 36 million tons food waste in 2012 alone, according to the EPA. Sending wasted organics to landfills, instead of anaerobic digesters and composters, is wasteful and damaging to the planet. By reducing the volume of waste material, BIOFerm™ biogas plants lengthen the lifespan of landfills, cut costs for tipping fees, increase the capacity of compost sites, reduce emissions, and decrease energy consumption for waste removal.
Reduction of greenhouse gas emissions
A large majority of food waste—from homes, grocery stores, restaurants, food processors, etc—ends up in landfills. In heaps of trash, organic waste decomposes and releases methane gas into our atmosphere; methane produces roughly 21 times the global warming potential of carbon dioxide. Reducing the amount of methane released into the atmosphere from organic waste is critical in ensuring a safe and healthy environment for ourselves and generations to come.Back
