Coal fly ash (CFA), a solid waste produced by coal-fired thermal power plants during the combustion of pulverized coal, is currently one of the largest solid wastes in China (Yao et al. 2015). In 2018, the annual output of CFA in China exceeded 550 million tons, and owing to insufficient utilization, the total accumulated CFA has exceeded 3 billion tons.

This study assessed coal fly ash and/or vinegar residue as additives in the green waste (GW) composting process and found the best treatment required only 23 days to produce a mature and high quality compost. Composting is an attractive way to recycle organic wastes because the product (compost) can be used as an organic fertilizer or a culture substrate.
