With the adoption of effective treatment systems, pollution from the M
alaysian agro-based industries, particularly natural rubber and oil pa
lm, has decreased in recent years. At present, domestic sewage and ani
mal wastes are the major sources of organic pollution load in the aqua
tic environment. The widespread and often indiscriminate use of pestic
ides has also resulted in detrimental effects on aquatic resources. Fu
rthermore, rapid industrial development and urbanisation during the pa
st two decades have given rise to the increased quantity and diversity
of toxic and hazardous wastes. The aim of maintaining the detrimental
effects of rapid industrialisation on the environment to a minimum wi
ll necessitate the evolution of current sustainable management practic
es to include environmental auditing, the incorporation of waste minim
isation strategies into manufacturing processes, as well as regular as
sessments of the effectiveness of mitigating measures.
