Disposal phase

Subsequently, an efficient method of ecological risk assessment was developed. It is based on a comparison of the predicted environmental concentration (PEC) and the predicted no-effect concentration (PNEC). If PEC PNEC, the substance under consideration is expected to pose no ecological risk in the environment. A comprehensive review about the ecological profile was provided by J. Steber.  

In the HERA project, a European voluntary initiative commissioned by A.I.S.E. (representing the formulators and manufacturers of household and industrial and institutional cleaning products) and CEFIC (representing the suppliers and manufacturers of the raw materials), the most important ingredients of laundry detergents are subject to a systematic risk assessment. This covers product safety from an ecological and human health perspective. The underlying reports are available to the public via the HERA website.

To recapitulate, the legs of the imaginary tripod on which the structure of materials science is assembled are atoms and crystals phase equilibria microstructure. Of course, these are not wholly independent fields of study. Microstructure consists of phases geometrically disposed, phases are controlled by Gibbsian thermodynamics. 

Activities may differ very much between Safety and Security depending on requirements. As an example, the Decommissioning and Disposal phase can be discussed briefly (Life Cycle Phase 16) ... 

The manufacture of a chemical product within a chemical processing plant is one stage of a product life cycle that includes the entire manufacturing and product assembly chain, as well as the use and disposal phases of the product. It is important to minimize the waste in the entire product life cycle, implying waste... 

The breakdown of energy for piece of cotton T-shirt shows that transportation, material, production, and disposal phases are dwarfed by the use phase. The use phase includes 25 washes at 60 °C, followed by tumble drying and ironing, that consume 60% of the total energy. The disposal phase includes incineration in which heat is generated and used so the net energy consumption is negative in this phase. 

The aim of the study has been to gain more information on consumer habits during the clothing disposal phase. The analysis is based on mixed methods with both qualitafive and quantitative parts. The qualitative method was based on a wardrobe study of clothing to be disposed of, and the quantitative method was based on a consumer survey. 

Disposal phase The end product is discontinued, destroyed, or otherwise discarded. 

The disposal phase may include disposal planning, phase-out, tear-down, or destruction and/or postdisposal or closeout phases. 

The analysis and control of hazards during the disposal phase should be addressed with an operating hazard analysis, a job safety analysis (a occupational and industrial safety tool), and/or change analysis. 

Inadvertent use of conflicting instruction labels, instructions, and/or operating procedures during the operational and even the disposal phases of the life cycle. 

LCA avoids the problem of moving the consequences of a process change, i.e., an apparent improvement in one part of a life cycle can merely lead to further problems at another time or place in the life cycle [21]. Figure 3.1 illustrates plastics waste management in terms of the life cycle of polymeric products. The disposal phase in LCA is often neglected or indicated as kilogram waste however, it has been established that the disposal phase should be included in... 

LCA studies [22], The risk of decisions shifting burdens from the production or use phase to the disposal phase because of data gaps can therefore be diminished. 

Each system will have a series of phases, which follow a chronological pattern the sum total of which will equate to the overall life-span of the system. These phases are conceptual phase, design and engineering phase, operational phase, and disposal phase ... 

The disposal phase begins when machinery and manpower are no longer needed to achieve the purpose of the system. All components must be effectively disposed of, transferred, re-allocated or placed into storage.
