Zusammenfassung:	•The feasibility of applying vermiculite in vermicomposting was first studied.•Vermiculite raised 13–24 % mineralization and 32–50 % CH4 and 31–62 % N2O reduction.•The specific surface area of vermiculite can affecting greenhouse gas emission.•The particle size of 3–5.5 mm improved bacterial interactions and network stability.•Vermiculite can accelerate the process of microbial succession. Greenhouse gas emissions during composting inevitably cause environmental pollution. This study investigated the effects of 10 % vermiculite of four particle sizes (
