Life Cycle Assessment of Recycling Processes for Demolition Waste

Popis výsledku v původním jazyce

This contribution is aimed to evaluate the environmental impacts of recycling construction and demolition waste with the use of Life Cycle Assessment. In the first step, the LCA was used as an analytical tool for the comparison of recycled aggregates production. Recycled aggregates were produced from brick and concrete waste. Chosen functional unit for the comparison was 1 ton of recycled aggregate (RA). The results show that concrete aggregate production has a higher impact on Climate Change category (1,51 kg CO2 eq.) than brick aggregate production (1,18 kg CO2 eq.). Then, in the second step, new concrete mixtures made of recycled aggregates were compared. Functional unit was 1 m3 of concrete. Environmental impacts of concrete mixtures were compared with reference concrete mixture. These compared concretes are classified as C20/25 according to CSN EN 206 + A1. Mixtures with concrete RA have a higher environmental impact than mixtures which were made of brick RA. GaBi Software ts for data processing was used. Environmental impacts assessment according to the ReCiPe method characterization, version 1.08 was used.
