See the attached PDF for UF's Trailer Digester.
Hello BESTers,
Here's a little tidbit from Sri Lanka. A local man has developed a small-scale portable digester to handle a household's food waste. It can treat about 2 kilograms per day and is about the size of a small refrigerator. Small-scale digesters are ideal for all types of situation from a rural family living off-the-grid to a small farmer producing fertilizer and energy from waste to a restaurant saving money on waste disposal. Everyone can benefit from small-scale, food waste digestion.
Have a great weekend,
Ryan
