The Environmental Impact of Recycled Concrete

methods to obtain recycled aggregates from concrete. One is crushed the concrete at a recycling plant facility and the other one is with a mobile plant. Each method uses basically the same procedures. The quality of materials which arrives at the recycling facilities is the part that recyclers have little or

Casting Concrete With Recycled Plastic Aggregate : 5 Steps

Casting Concrete With Recycled Plastic Aggregate: One of the biggest challenges with recycling is plastic. There's not much of a market for scrap plastic, so the profit margins on processing and reselling it are slim. When oil prices dip, it becomes cheaper to make new plastic than to recycle exist…
