One of the most pressing problems today is what to do with various waste products. Recent legislation mandated that certain wastes can no longer be deposited in landfills, and tipping fees are on the rise. Composting is a very acceptable and viable option for handling most organic wastes presently being landfilled. Windrowing is the most efficient and economical composting method and may be accomplished within a building, out-of-doors or under a simple roof. We employ other composting technologies as conditions require.

In-Vessel Composting process using modified 20 to 55 ton roll-off or intermodal containers for converting organic resources into valuable compost products. Systems range in size from four up to one thousand tons per day. There is "manual, automated and fully automated" with new or retrofitted digester programs to fit any budget need. The stackable digesters, biofilters, and curing bins can be located in the smallest possible area, even close to residences and businesses. The transportation savings alone are outstanding. With containerized composting, composting buildings, large concrete surfaces, and stormwater treatment basins are eliminated. Enclosed composting keeps odorous composting-process air from escaping to the atmosphere, leaving it concentrated for scrubbing in a biofilter.

These systems can range in size from 5,000 to 100,000 tonnes per year capacity. Raw waste is placed in one end and compost is removed from the other end after 4 to 8 weeks. These systems can be totally enclosed and connected to a biofilter in cases where odor may be a concern. Composting temperatures of 55 to 65oC are maintained by powerful centrifugal blowers that provide air to the composting material. The composting material is mixed once or twice weekly using a Compost Turner. The remote controlled Transform Compost Turner turns the material once to three times weekly. The Turner mixes the material, breaks preferential pathways, and moves the material down the composting channel. A transfer carriage moves the compost turner from one channel to the next. Air for the composting is supplied by three centrifugal blowers to a network of PVC pipes under the composting material. The blowers are controlled by timers and/or temperature feedback. Temperature monitoring and blower controls can be done through computer control as well.
