 Composters |
Although to date, composters have not been considered as “Energy-from-Waste” systems, we are able to use them as such.
The composting process is a net provider of heat, and we can capture that. The product (compost) may not have a high market value (due to local market demands and the highly competitive nature of the industry), so unless our client specifically needs the compost, we might suggest to gasify the products to give us “Energy-from-Compost”.
The composting process is able to handle “wet” feedstocks, that include manures and mortalities, so what we are able to do, is extract that energy from these normally landfilled materials. Rotary composters are basically slowly revolving tubes in which the feedstocks are placed in at one end, rotated, self heat and after all the pathogens are killed, the compost can be removed at the other end.
Generally, rotating composters:
-
Are hassle-free and continuous in operation ie: load feedstocks (eg: carcasses and shavings) into the tank, rotate it for few hours every day, and let nature do the rest.
-
Have the capacity to handle any amount of feedstocks, and can process them into compost in 4 to 14 days.
-
Minimize employee operating time to achieve the desired results, compared to other composting systems.
-
Operate outdoors during winter months, because hot and moist air from building or barn exhaust fans can used to keep conditions inside the composter at an ideal level.
