The Cement Sustainability Initiative (CSI) has been looking at the recycling of concrete as a component of better business practice for sustainable development. Concrete has fairly unique properties and its recovery often falls between standard definitions of reuse and recycling. Concrete is broken down into aggregate for use in a new life.

At the end of a building’s life, demolition generates large amounts of materials that can be reused or recycled, principally wood, concrete and other types of masonry, and drywall. Rather than demolish an entire building, consider “deconstructing” all or part of the structure.

The ability to recycle and reuse concrete and demolition waste is critical to reducing environmental impacts in meeting national, regional and global environmental targets. Handbook of recycled concrete and demolition waste summarises key recent research in achieving these goals.

1.2 Earlier work on concrete recycling The environmental impact caused by the manufacturing of new cement and its negative effect on human health, such as dust and ash, has led to an increased interest in the reuse of C&DW (concrete and demolition waste). Previous studies and tests that have been done on the reuse

Highlights of the Second International RILEM Symposium on Demolition and Reuse of Concrete and Masonry, held in Tokyo, Japan, in November 1988, are described. Eighty-three papers were presented at the symposium: 54 on demolition and 29 on reuse.

Concrete and Aggregates Demolition Metals The Wisconsin Department of Natural Resources is removing and recycling concrete that made up the West Silver Wetland Dam in Fort McCoy, a report by the Tomah Journal says .

Sustainable reuse of brownfield properties includes efforts to reduce the environmental impact by reusing and recycling materials generated during building construction, demolition, or renovation. Typical construction and demolition (C&D) materials include wood, drywall, cardboard, brick, concrete, metal, insulation and glass.

Concrete crushing is a process in which we grind concrete into gravel that you can reuse and recycle. Before our Oregon demolition experts can crush concrete, they tear down the respective building using precision equipment, such as high-reach excavators with attachments.

Recycling concrete helps reduce construction waste and extend the life of landfills as well as saving builders disposal or tipping fees. It also reduces transportation costs because concrete can often be recycled in areas near the demolition or construction site.

In fact, concrete recycling is an increasingly common method of utilizing the rubble. At one time, concrete was commonly trucked to landfills for disposal, but the benefits of recycling has made it a more attractive option, especially in light of more stringent environmental laws, and for keeping construction costs down.

Recycling concrete from demolition project can result in considerable savings since it saves the costs of transporting concrete to the landfill (as much as $ .25 per ton/mile), and eliminates the cost of disposal (as high as $100 per ton).

Since 1952, Cherry has made demolition projects a turnkey process—from deconstruction to recycling to disposal. We own and operate one of the largest equipment fleets in the Gulf Coast and our trained professionals provide the highest quality service.

Reuse and Recycling of Construction and Demolition Project Debris Introduction Construction and demolition (C&D) debris is generated during new construction, renovation and/or demolition of existing buildings and structures, and land clearing. C&D debris includes bricks, concrete, masonry, soil, rocks, lumber, paving materials, shingles, glass ...

It includes reviews and reports of recent developments in the fields of demolition techniques and reuse of waste building materials, and focusses on the integration of demolition and recycling operations in the construction and housing industry.

Demolition or razing is the tearing down of buildings and other man-made structures. Demolition contrasts with deconstruction , which involves taking a building apart while carefully preserving valuable elements for reuse purposes.

developing new concrete product is technically viable and may, in some circumstances, be environmentally beneficial. Recycling is an important process which is used to produce a useful source of aggregate for the construction industry. Concrete recycling is increasingly becoming popular way of utilizing aggregate left behind

The concrete crusher at Elder Demolition makes us one of the most environmentally proactive demolition companies in Oregon and the Northwest. The impressive equipment crushes pieces of concrete into reusable gravel we recycle onsite—a key component of any green demolition project.

Concrete was once routinely trucked to landfills for disposal, but recycling has a number of benefits that have made it a more attractive option in this age of greater environmental awareness, more environmental laws, and the desire to keep construction costs down. Concrete aggregate collected from demolition sites is put through a crushing ...
