Agricultural wastes from agri-based industries, such as palm oil, rubber, and wood processing factories have increased by more than threefold. Selangor, Perak, and Johor collectively account for 65.7% of the total number of identified sources of pollution in the manufacturing and agro-based sectors (DOE, 2010). Another significant source of pollution is livestock waste, which is a big contributor to BOD. A recent report provided by the Veterinary Services Department showed that the standing pig population (SPP) of the WCPM was approximately 717 SPP/farm (Ibrahim et al., 2010; Singh & Fong, 2014). Pig farms generate large quantities of waste and some of these farms discharge effluents directly into estuaries and tidal rivers without any pretreatment. The report indicated that most of the pig farms (82%) in Selangor and Negeri Sembilan not only pollute the water with parasites and bacteria, but also exert high demand for oxygen and cause eutrophication.
Why is waste processing important?
When waste is disposed of or recycled in a safe, ethical, and responsible manner, it helps reduce the negative impacts of the environment. Ensuring that waste management procedures are carried out with regularity helps ensure that fewer waste materials go to the general waste stream.
