[Authors: Donn Joseph R. Batuyong, Bryan Carlos B. Acain, Luis Gabriel F. Maniago, 2015] Waste can be regarded as a human concept as there appears to be no such thing as waste in nature. The waste products created by a natural process or organism quickly becomes the raw products used by other processes and organisms. Recycling is predominant, therefore production and decomposition are well balanced and nutrient cycles continuously support the next cycles of production. This is the so-called circle of life and is a strategy clearly related to ensuring stability and sustainability in natural systems. On the other hand there are man-made systems which emphasize the economic value of materials and energy, and where production and consumption are the dominant economic activities. Such systems tend to be highly destructive of the environment as they require massive consumption of natural capital and energy, return the end product (waste) to the environment in a form that damages the environment and require more natural capital be consumed in order to feed the system. The presence of waste is an indication of overconsumption and that materials are not being used efficiently. This is carelessly reducing the Earths capacity to supply new raw materials
