A solid waste recovery system processes solid wastes which would otherwise be sent to a landfill by utilizing several stages of systematically separating and processing various components of the refuse. Refuse is trucked in and dumped on a tipping floor of the recovery facility and separated into non-compostables, recyclables, and compostable materials. The non-compostables are further separated into recyclable inorganics which are recaptured as resalable items and into non-compostable organics which are further separated into hospital and clinical wastes to be incinerated or disposed of as hazardous waste, and into petroleum products to be incinerated, sent to a landfill or disposed of as hazardous waste, or recycled. The refuse remaining on the tipping floor is further separated into fuel items for resale or heating the facility, into recyclables which are processed for resale, and into compostables which are blended and ground into fine particles for resale or sent to a compost pad for conversion into compost for resale. The solid waste is recaptured in the form of baled paper and cardboard material to be sold to a paper recycling mill and containerized recyclables such as plastic, glass, aluminum, ferrous metals, etc., to be sold to their respective mills. The non-recyclable refuse is processed into fine particles to be sold in bulk as fluff or after further processing to be sold as compost fertilizer.

A combined physical and chemical process for recycling of solid waste into recoverable resources comprising the steps, in sequence, of: separating said solid waste into non-compostable, recyclable, and compostable items, said step of separating said solid waste including removing any large wood item

A combined physical and chemical process for recycling of solid waste into recoverable resources comprising the steps, in sequence, of: separating said solid waste into non-compostable, recyclable, and compostable items, said step of separating said solid waste including removing any large wood items present and sending them to a wood chipper and mixing said wood chips with other compostables for conversion into compost, separating and removing recoverable cardboard and paper items from said solid waste, blending non-recoverable cardboard and paper items with said compostable material for grinding into fine particles for processing into compost, blending said mixture of compostable items, wood chips, and non-recoverable paper and cardboard items and grinding the blend into fine particles of compostable material, placing said fine particles into transport containers and sending them to a compost pad configured such that water or residue from composting material will run off into a holding pond and having a protective covering to prevent seeping or leaching of liquid residue into the earth or water supply, dumping said fine particles from said transport containers onto a compost pad in windows, mixing said fine particles of compostable material with bacteria, chemicals or other organic matter operable to initiate composting by initiating the decaying process of said fine particles of compostable material and of the organic substances contained therein, curing said decayed compost material by pumping water onto said compost windrows, manipulating and blending said windrows of fine particle material until consistent in texture, subjecting samples of said blended materials to a carbon:nitrogen ratio test, and if the ratio is determined to be an unsatisfactory percentage, adding additional chemicals to said blended materials to obtain a predetermined proper ratio, checking and recording the temperature of said blended materials, checking and recording the moisture of said blended materials and adjusting the moisture if required, p1 after said blended materials have been determined to have the predetermined carbon:nitrogen ratio, temperature, moisture, and chemical or bacterial content, manipulating said blended materials again and allowing them to cure, after curing, sifting and grading said cured compost material, returning the coarser composted materials unsuitable for use as compost to said compost pad for re-composting, and weighing, bagging, and sealing said sifted compost material for resale to appropriate markets suitable for use as compost or fertilizer.
