Economic profitability of the secondary materials utilization as a substitute of raw materials

摘要: Any product has a possibility of turning into waste when it loses its economic value with the passing time. Once raw materials are used and is created, properties not necessarily lost but can be restored using regenerative processes. Despite fact that primary have been lost, still carries both subjective human work energy in production. Differences between secondary (waste) those substantial; many times these changes only superficial. The reason often undergone fundamental during production process. Waste accumulates over time unless decomposed ecosystem or recycled. Today, accumulation reached such magnitude become real threat to existence whole (Li-Teh et al.). promotion environmental management mission sustainable development worldwide exerted pressure for adoption proper methods protect environment. hierarchy disposal options, categorizes impacts six levels, from low high: reduce, reuse, recycling, compost, incinerate landfill. Recycling, being one strategies minimizing waste, offers three benefits: reduce demand new resources, cut down on transport costs, utilize which would otherwise landfill sites (Xavier al. 2006).
