Kinetic Study of Laboratory Scale Composting Process

Solid waste generated in Malaysia constitutes of large portion of organic material that can be readily composted. Compo sting which dispose off the organic material, and at the same time producing usable compost as the end product is thought to be a good option for organic wastes disposal. This p...
