The building material industry needs to adopt circular economy practices to handle the large volume of construction waste, given both increasing regulations on waste disposal and limited landfill space. As a result, material recycling technologies that convert waste into valuable feed resources for the building materials or other end-use applications are coming into greater focus. To determine the economic feasibility of the circular economy principles , we conducted case studies for recycling of three waste streams - carpet, concrete aggregates, and tire waste - and identified driving forces and barriers for each. We also built cost models and evaluated the profitability of recycling operators in these cases. According to these analyses, concrete aggregate recycling earns attractive profit margins, but faces the hurdle from the irregular supply of demolished concrete. Tire recycling by cryogenic grinding also generates decent margins, with even greater returns available if recyclers can improve the product's incorporation rate into tire manufacturing process. Carpet recycling has low margin and needs to target consumers with an additional sustainability goal and willingness to pay a price premium.

Table of Contents



While a rising trend in the building material industry, the circular economy varies widely among sub-industries due to different regulations, value chains, market drivers, and barriers


Carpet, concrete, and tire recycling processes offer markedly different profit margins.
