Abstract

Disclosed are novel engineered fuel feed stocks, feed stocks produced by the described processes, and methods of making the fuel feed stocks. Components derived from processed MSW waste streams can be used to make such feed stocks which are substantially free of glass, metals, grit and noncombustibles. These feed stocks are useful for a variety of purposes including as gasification and combustion fuels.

Abstract

The present invention provides integrated bunker storage systems for waste streams based on the composition and characteristics of waste streams. In particular, the present invention provides a process for generating individual waste streams based on a set of material characteristics. According to the system and method of the present invention, individual waste streams from wastes stored in bunkers are mixed in a given feed ratio to generate a feed stock that will produce a desired output from a chemical conversion process, e.g., gasification. Optionally, composition data regarding the feed stock can be certified to a third party.

Abstract

Disclosed are novel engineered fuel feed stocks, feed stocks produced by the described processes, and methods of making the fuel feed stocks. Components derived from processed MSW waste streams can be used to make such feed stocks which are substantially free of glass, metals, grit and noncombustibles. These feed stocks are useful for a variety of purposes including co-firing with coal and as substitutes for coal.

Abstract

Systems and methods for sorting a plurality of recyclable items in a single- stream materials recovery facility (SSMRF) are provided. In some embodiments, a system includes an infeed conveying system, a fiber transfer conveyor, a container transfer conveyor, and a glass sorting and conveying system. The system further includes a controller configured to obtain total weight and volume of recyclable items at the infeed conveying system. The controller estimates a percent weight of fiber items and a percent weight of non-fiber items relative to the total weight. Based on the estimates, the controller controls speed of at least one of the infeed conveying system, the fiber transfer conveyor, the container transfer conveyor, and the glass sorting and conveying system.

Abstract

One embodiment of the present invention includes an identification mechanism, such as a radio frequency identification (RFID) tag or barcode, associated with a waste container. The identification mechanism contains an identifier that can be used to identify the waste container, and that can be read by a vehicle with an identification reader. In addition, the location of the waste container can be determined using a GPS receiver. The waste container identifier and its corresponding location can then be stored in a computer for later transmission to a second computer, for example, by using a wireless communication link. The second can be used to associate the waste container identifier and the waste container's position with a customer.

Abstract

A system and methods for managing a recycling program including the step of receiving waste materials from a user and the step of receiving recyclable materials from the user. Further, the step of measuring a quantity of waste materials received and the step of measuring a quantity of recyclable materials received. Further still, calculating a user- specific diversion rate based upon the ratio of recyclable materials as compared to the sum of recyclable materials and waste materials. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

Abstract

A system and methods for encouraging a user to continue recycling behavior through various rewards systems and economic benefits, each of which contribute to the overall efficiency and sustainability of a recycling program. The system includes both hardware and software components that are adapted to receive, quantify and assess the quality of recyclable goods. Further, a method includes cooperating with the system to provide users with economic incentives to increase both the quantity and the quality for recycling. Further still, a method includes steps of receiving recyclables from a recyclables container associated with a user, electronically capturing data relating to individual recycled items, and providing a benefit to the user associated with the recyclables container in response to both the quantity and the quality of the recyclables received.

Abstract

Methods off creating a batch of recycled glass from mixed color glass cullet. In one embodiment, the method includes receiving at a glass plant a weight and color composition percentage of a first batch of mixed color cullet. The glass plant also receives a weight and color composition percentage of a second batch of mixed color cullet. The weight and color composition percentage of the first batch and the second batch are combined to generate a combined weight and composition percentage. The combined weight and composition are percentage are used to generate, automatically at a glass plant, a formulation to produce glass of a desired color.
