More than 60,000 tons of waste from Carya illinoinensis, known as pecan, are produced yearly in Mexico. Usually, these wastes are either open-cast disposed of or burned, causing environmental issues. An alternative to combustion is gasification, which transforms biomass into syngas and ash. Using a catalyst can improve the gasification reaction since it allows for better heat transfer in the reactor. In this work, a gasification process catalyzed by a clinoptilolite was evaluated as a method of pecan waste management. A fixed bed gasifier in batch mode with a reaction volume of 1 kg was considered. Gasification with 8 % zeolite presented the shortest reaction time (39 min) and the highest average flow of synthesis gas (0.779 m3/5 min). The environmental impact was evaluated through a life cycle assessment considering two scenarios: conventional and catalyzed gasification (2, 4, 6, and 8 % of zeolite). In the former, the gasification stage induces the largest potential impact (>95 %) in all the categories, and global warming is the most affected category (>90 %). In the second scenario, gasification (82 %) and zeolite production (16 %) stages are the main potential impact inducers; global warming is also the most affected category (85 %). Considering the experimentation and environmental assessment, gasification with 8 % zeolite was selected for the next stage. Regarding economic feasibility, it was found that a pilot-scale gasification processing 1000 kg of pecan waste becomes feasible if gas is either sold or used to produce electricity.
