No commercially viable processes exist to recycle cement. Compared to other wastes, concrete is relatively inert and does not usually require special treatment. The physical properties of coarse aggregates made from crushed demolition concrete make it the Get price

Wind turbine blades cause issue with waste

The EcoPoly Pellets are made in part from recycled wind turbine blade material, giving new life to the blades that were previously viewed as unrecyclable. In the press release, GFS states explains this recycled pellet "represents the company's innovation in repurposing waste material (decommissioned wind turbine blades) into green manufactured products that are commercially viable."

Recycling Used Oil Filters

The end result is a collection drum filled with recyclable metal "pucks" and a storage container of used oil that can be recycled, all while complying with EPA disposal guidelines. Because most disposal companies charge a collection and hauling fee for each drum, the more recycled filters you can fit into each drum, them more you'll save. Get price

GLASS CRUSHERS

The GB Series Glass Breakers are complete crushing systems. Rugged, unitized construction produces a machine that will withstand years of punishing use in recycling operations. The GB series requires minimal maintenance and has a reputation in the recycling industry as a crusher built to last. Process "line-rejects" or "out-dated product" and recover recyclable glass with Get price

Recycled Concrete Aggregates: A Review

2013/3/29This paper discusses the properties of RCA, the effects of RCA use on concrete material properties, and the large scale impact of RCA on structural members. The review study yielded the following findings in regards to concrete material properties: (1) replacing NA in concrete with RCA decreases the compressive strength, but yields comparable splitting tensile strength; (2) the modulus Get price

Asphalt

Recycled Asphalt is asphalt that has been removed from existing paved roads and reconstituted. This dry product is crushed/broken back down into manageable particle sizes. The particles are then at a size that allows for efficient reheating of product that assist with the rejuvenation process. Get price
