Reducing and Reusing Basics The most effective way to reduce waste is to not create it in the first place. Making a new product requires a lot of materials and energy - raw materials must be extracted from the earth, and the product must be fabricated then transported to wherever it will be sold.
Benefits of Recycled Aggregate: The use of recycled aggregate can save money for local governments and other purchasers, create additional business opportunities, save energy when recycling is done on site, conserve diminishing resources of urban aggregates, and help local governments meet the diversion goals of AB 939.

Plastics Make It Possible® is a wonderful resource for determining what items you can and cannot recycle. Instead of tossing plastic cups and utensils, simply wash and reuse them. Use old plastic items in fun new ways. Photo Credit: Jessica Kielman How to
Mar 05, 2020 · In the demolition industry waste reuse, recycling and up-cycling is common practice. Aggregate arisings such as brick, concrete etc. are segregated, crushed and graded for reuse. Reprocessed aggregates arising have a variety of uses they can be used on site, such as: a sub-base for buildings; roads; and backfill for voids.

For constructing a pavement or road mainly used materials are aggregates, bitumen and soil. Desirable properties of road aggregates are its strength, hardness, toughness, durability, shape of aggregate and adhesion with bitumen. In this study properties of aggregates such as strength, toughness and specific gravity of recycled aggregates.
Using recycled aggregates instead of extracted aggregates would qualify as post-consumer. Because concrete is an assembly, its recycled content should be calculated as a percentage of recycled material on a mass basis. Credit can also be obtained for Construction Waste Management.
Single-sized recycled aggregates and recycled sand As soil washing technology develops, Tarmac can now offer recycled sand and single sizes for use in a variety of drainage and bedding applications as well as offering a cost-effective alternative to primary aggregates.

There are two main reasons to recycle concrete and asphalt. The first is efficiency—often, the cost to recycle material is less than the cost of disposing of material in a landfill. That, coupled with the cost savings on the use of recycled material, makes recycling an economically appealing option.

The present state of knowledge on the use of recycled concrete as an aggregate in new concrete is reviewed and suggestions made as to what further work is necessary before a proper assessment of the material can be made. Where crushed uncontaminated concrete is used the properties of the material as an aggregate and the basic engineering characteristics of the concrete made with it are well ...
According to a FHWA study, 38 states recycle concrete as an aggregate base; 11 recycle it into new portland cement concrete. The states that do use recycled concrete aggregate in new concrete report that concrete with recycled concrete aggregate performs equal to concrete with natural aggregates.

RCA are aggregates obtained by recycling of clean concrete waste where content of other building waste must be very low – less than a few percent. For example, British standard BS 8500–2 ( BSI, 2006 ), defines RCA as recycled aggregate with maximum masonry/fines content of 5%, maximum lightweight material/asphalt content of 0.5% and maximum other foreign materials content of 1%.
