Environmental impact and waste management

Michael J. Boyer AWT-Agribusiness and Water, Camming, Georgia, Environmental Impact and Waste Management. 

A thorough analysis and evaluation of different fuel cycles with regard to economics, environmental impacts, nuclear waste management and proliferation risk is given by the MIT (2003). 

Students are also very environmentally aware. Adding the microwave component has provided the opportunity to introduce many of the concepts of green chemistry. The role of solvents in a reaction can be exemplified by having students compare changes in reactions that under traditional microscale procedure used toluene or DMF as solvents but are now run in ethanol and water. The issues of solubility and boiling point properties are compared to enviromnental impact and waste management. For example, water need not necessarily be the optimal solvent for a reaction. Not only does the reaction step itself have to be considered but also the enviromnental impact of product workup and waste disposal in order to make an informed decision on the benefits of a particular solvent.

As the reader has observed in this review, the innovation process is thriving within this new environment. The focus has been on more cost effective polymerisation plants with an improved environmental profile, the replacement of lead stabilisers, scientific studies and support for phthalates, a greater understanding of and an increasing role for impact modifiers, recycling techniques and waste management possibilities. 

Environmental Chemistry can also be applied to treat wastes, and to prevent and reduce the impact of certain discharges into the environment. A basic knowledge of chemistry will allow for a more-detailed understanding of processes such as water and wastewater treatment, air pollution control, and waste management. 

With the growing awareness for the protection of the environment, there is a greater need for producers to improve the environmental profile of their products. Consumers and regulatory bodies expect more information on the effects of products on the environment during their manufacture, use, and disposal. The Life Cycle Assessment (LCA) is used as a holistic approach to assess the impact of a product throughout its life cycle. An important aspect of LCA is recycling and waste management. 

The ability of any laboratory to operate in a manner that minimizes risks to personnel and the environment is dependent on laboratory workers who understand and carry out prudent practices for handling, storage, and disposal of chemicals. Training of laboratory personnel in safety and waste management is essential and must be followed up with an appropriate inspection system to ensure that safe practices are fohowed. Safety training must include discussion of chemical hazards, equipment hazards, laboratory safety and environmental systems, and the potential impact of laboratory work on these systems. 

Part III comprises a thorough description of the roles of clays in environmental protection and degradation. The environmental impacts of clay mining, beneficiation and clay-related industries and the natural processes by which clays protect the environment are explained in the initial chapters of Part III. The next chapters introduce the application of clays and their derivatives to resist pollution, recycling of industrial waste products and waste managements (for both toxic and non-toxic wastes). 

Current development activities are focused on the processes and practices of reprocessing plastic waste materials, with emphasis on the processes and practices that reduce emissions and integrate the LCA of technologies and materials. Plastics processing management involves the reuse of plastics waste from industry, and primary and secondary recycled material, to limit the environmental impact and preserve natural resources. 

Industrial ecology is a recent concept in engineering and management, and is an attempt to manage an industrial unit as an ecosystem, with feedback loops and the minimal use of resources and production of waste [7]. Life cycle assessment, which was designed to take into account the environmental impact of waste, can help achieve cleaner production technologies and sustainable waste management practices which are all important aspects of... 

The Environment Report (Reference 1.12).describes those elements of the APIOOO design that could directly impact a generic UK site. The Environment Report itself is supported by several technical reports, including the APIOOO Disposability Assessment - UKP-GW-GL-012 (Reference 1.13)andthe APIOOO Integrated Waste Strategy (Reference 1.14). Information from the Environment Report is used to imderpin those claims in the PCSR that refer to the management of environmental impact and radioactive waste disposal.
