Effect of Passive Aeration on Conventional Composting of UTP Organic Wastes for Value-added Products

Composting is a method of converting organic waste into value-added products. The outcomes are usually nutritious fertilizers and this method has been practiced for decades especially by farmers. Universiti Teknologi PETRONAS (UTP) is generating wastes at a high volume daily. There is a significant...
