Oct 25, 2017 · “Our technology takes plastic out of the landfill, locks it up in concrete, and also uses less cement to make the concrete, which makes fewer carbon dioxide emissions. This has the potential to pull plastic landfill waste out of the landfi

Here in Portland, Oregon, there is a local company which collects pieces of broken-up concrete sidewalks and driveways. They make landscape features (mostly retaining walls) by mortaring the concrete chunks vertically to produce what resembles a f...

The Bath-led research—in partnership with colleagues from Goa Engineering College, India – has shown how replacing 10 per cent of sand in concrete with waste plastic may help to reduce the vast amounts of plastic waste on India's streets, and deal with a

Recycling Concrete. Arrangements can be made to haul concrete from a demolition site to the recycling plant, or, in some cases, recyclers are able to move portable recycling machinery to the plant site. In terms of the overall environment, recycling conc

Enter your city or zip code in the location blocks and type "Concrete" in the search bar. Then call matching recycling centers to find out when they are open. Load the concrete blocks into your car or truck and drive them to the recycling center.

Recycling of waste concrete is done to reuse the concrete rubble as aggregates in concrete [6, 17]. The recycled aggregate have less crushing strength, impact resistance, specific gravity and has more absorption value as compared to fresh aggregates. Mill

The experiments were done by using the waste of polyethylene packages include bottle and food crates in the range of 10% to 80% by volume as a short reinforcement structure. The results show that there is a possibility to produce plastic cement from polye

At the end of any construction project, there's bound to be a large amount of debris. But what looks like disposable material could turn into a money and time saving opportunity. Leftover concrete is a valuable source of material, often used as a subbase
