Life cycle assessment environmentally degradable

Process design the report includes sections that discuss the use of techniques such as risk and life-cycle assessments to provide a holistic view of a product s environmental impact. Examples of environmentally adapted products include solvent-free lacquers, biologically degradable lubricants and catalysts for VOC and NOx reduction. 

Degradation is likely responsible for several damages to any rubber blend and is related to environmental impacts. Analysis of the life cycle and control of different degradation processes that blends, can be submitted to allows understanding of how many different phenomena occur. This understanding is essential to develop new blends where the properties of two or more polymers can be combined. This work covers some developments in life-cycle assessment, ageing and degradation behaviour of natural rubber-based blends and IPNs. 

It is sometimes assumed in that polymers from renewable resources are by definition environmentally friendly , or in modern parlance, sustainable . One definition of sustainable suggests that the development of new products for the benefit of society should not have an unacceptable effect on resource depletion and environmental pollution. However, unacceptable is a relative term and invites comparison of one material with another by life-cycle assessment (LCA). Companies engaged in the development of degradable polymers from renewable resources have initiated life-cycle assessment comparisons of their products with the commodity synthetic polymers, notably polyethylene. It has not so far been shown unambiguously that bio-based polymers are more environmentally sustainable than the present range of commodity polymers . This results from the same reason that led to concern in the 1980s namely lack of consistency and uniformity of the assumptions made. In some cases they actually contradict one another.

Due to the rapid introduction of new products and models, the physical reliability life of a product (particularly in consumer-oriented markets) is often different from the market life of the product. The reutilization and repurposing of components and subassemblies through multiple product life cycles is a key enabler to proactively, intelligently, and economically manage the total environmental life cycle of electrical and electronic products (Ref 27). Such an approach will require accurate reliability degradation assessment of the components and sub-assemblies at the end of each product life cycle, and reliability life prediction for the next product life cycle. It is believed that such capabilities towards a comprehensive and integrated solution to the total environmental life cycle of electronics products will provide competitive advantages for players in the industry worldwide.
