In an innovative plan, a California waste water plant is using anaerobic digestion to convert food waste into energy and compost. Rather than dumping it in a landfill, the East Municipal Bay Utility District is currently recycling 90 tons of food waste per week and plans to increase that to 200 tons per week. They are the only such facility in the country. Imagine the benefits if municipalties everywhere did this.
We already have most of the solutions we need for a renewable energy, low carbon, cleantech future. All we have to do is do it.
Rather than dumping it in a landfill, many sewer processors (including the local one at Cedar City, Utah) compost it and give it away (free!) as fertilizer for non-food uses. I’m not saying fuel is a bad thing– just that landfill isn’t the only alternative.
