•Eggshell waste (ES) recycling in self-heating composting reactors was investigated.•Potato peel, grass clippings and rice husks were the starting composting materials.•ES incorporation did not affect the self-heating capacity of the mixture.•Nitrogen losses were enhanced by ES during thermophilic p...
