Glass Waste

The use of the recycled glass as aggregate in concrete has become popular, with large-scale research on that application being carried out at Columbia University in New York. Recycled glass greatly enhances the aesthetic appeal of the concrete. Recent research has shown that concrete made with recycled glass aggregates have better long-term strength and better thermal insulation, due to the thermal properties of the glass aggregates. Glass which is not recycled, but crushed, reduces the volume of waste sent to landfills. Waste glass may also be kept out of landfill by using it for roadbed aggregate or landfill cover.

KIB Ltd glass aggerates, a mix of colors crushed to a small size, is substituted for pea gravel or crushed rock in many construction and utility projects, saving communities in Kenya, thousands of dollars (depending on the size of the project). Glass aggregate is not sharp to handle. Common applications are as pipe bedding—placed around sewer, storm water or drinking water pipes, to transfer weight from the surface and protect the pipe. Another common use is as fill to bring the level of a concrete floor even with a foundation and also as a company we use the end products into our production line in most of our products of Landscaping.

Other uses for recycled glass include:

• Fiberglass insulation products
• Ceramic sanitary ware production
• As a flux in brick manufacture
• Astroturf
• Agriculture and landscape applications, such as top dressing, root zone material or golf bunker sand
• Recycled glass countertops
• As water filtration media
• Abrasives
