| Abstract |
Developing countries suffer from both lack of resources and appropriate solid waste management systems. Therefore, the introduction of alternative options for waste valorisation is imperative. The current research in-troduces an environmental Life Cycle Assessment (LCA) of waste-based briquettes produced with 80 % of non -recyclable cardboard waste from separate collections and 20 % sawdust from sawmills in Bolivia. The aim is to compare the environmental impacts generated within the briquette's life cycle with conventional fuels. Primary data from a development project implemented in La Paz in 2021 were collected for building the inventory. SimaPro9.0 was employed to conduct the analysis, with IMPACT2002+ as the impact assessment method. Re-sults' normalization, contribution evaluation, interval assessment, and sensitivity analysis were carried out, and the results were compared with conventional fossil fuels, namely: coal, methane, and LPG. Results suggest that briquettes' life cycle contributes to seven of fifteen impact indicators, with global warming, use of non-renewable energy, and respiratory inorganics, the most important. The global warming potential ranges from 23.9 to 26.7 gCO2-eq. MJ-1, lower than about 485 % compared to coal and 185 % to methane. Considering the avoided impacts from wood and methane substitution, global warming potential can decrease to about 20.0 and 18.9 gCO2-eq. MJ-1 respectively. On balance, compared to other fuels for heating and cooking, waste-based briquettes always have better environmental performance transporting the briquettes to about 100-130 km from the production plant. These results suggest that waste-based briquettes can contribute to mitigating environmental impacts and carbon footprint at a global level. |
