Produção e reciclagem de gesso acartonado: análise energética e ambiental

Gypsum drywall is widely used in the construction industry due to its practicality and performance, but its improper disposal generates significant environmental impacts. This study applies Life Cycle Assessment (LCA) to compare the environmental impacts of five scenarios involving the production and disposal of gypsum drywall waste: conventional production of panels and gypsum powder, dry and wet recycling, and landfill disposal. Two impact categories were analyzed: global warming and cumulative energy demand. The results show that recycling scenarios help reduce greenhouse gas emissions and dependence on natural resources. Transportation was identified as the most energy-intensive stage across the different scenarios. The study highlights the importance of public policies and incentives for recycling infrastructure, identifying gypsum drywall recycling as a viable strategy to consolidate sustainable practices and advance toward a circular economy in the construction sector. Furthermore, the data obtained support more informed decision-making by public administrators, companies, and professionals in the field, contributing to the development of technical guidelines and regulations that encourage proper waste management. The integration of urban planning, technology, and environmental responsibility proves essential to mitigate the impacts of the construction sector and transform waste into resources within a more efficient and sustainable production cycle.
