In this case, the HORSE is a ‘living’ machine, not an animal, and has the potential to reinvent the food cycle.
We have a huge food waste problem, not only in the US, but all over the globe, and while the issue really needs to be addressed on the upstream side, we also need viable solutions on the downstream, or consumer side, for converting biodegradable waste of all sorts into a usable resource. Composting is one great option, but it does require time, space, and infrastructure to support it, so it can’t be a one-size-fits-all solution without a major shift in the way we deal with our waste on a local and regional level.
However, one potential solution may lie in what’s called the HORSE, or High-solids Organic-waste Recycling System with Electrical Output, device, currently in development from Impact Bioenergy. This portable anaerobic digestion system can accept a wide variety of organic waste materials, ranging from kitchen scraps and yard waste to paper products, and generate both liquid fertilizer and energy in the form of biogas and electricity.
Assuming one of the devices could be placed in each neighborhood or community (accompanied by a rigorous recycling and overall waste-reduction program), the HORSE system could eventually “eradicate curbside garbage pickup” and avoid the carbon emissions associated with that element of waste management.
