  • To research the volume and components of solid waste, we surveyed household waste with three different incomes (high, middle and low incomes). Then waste is separated into 34 waste components and 9 main waste groups containing organic waste (easily decomposed waste such as vegetable, root, fruit, left food.. to make the compost and difficultly decomposed waste), paper, plastic, metal, glass, rubber and leather, cloth, dangerous substance, and other waste. Besides, definition of all groups of waste is also discussed. ...

  • Depletion of mineral resources is one of the major problems in the world. We have consumed available resources as if they were unlimited, and at the same time we generate a huge quantity of waste, thereby contaminating the Earth. The amount of waste in our society reflects how much resources we consume. We, as modern society, create more products and packaging which is visually appealing but cannot be easily decomposed. Energy demands, resource limitations, and environmental pollution are closely linked.

  • The steady increase in industrialization, urbanization and enormous population growth are leading to production of huge quantities of wastewaters that may frequently cause environmental hazards. Raw or treated waste water is very oft en discharged to freshwaters and results in changing ecological performance and biological diversity of these systems. About 70% of water supplied ends up as wastewater and several natural water reservoirs are being contaminated by untreated sewage/industrial effl uents. This makes waste water treatment and waste water reduction very important issues....

  • The regional effects on agricultural income follow from price and quantity impacts on the input and output side. The bottom line in terms of agricultural income is crucially determined by the impacts on revenues from raw milk and meats and related impacts on non fodder items. While fodder activities are important for a detailed analysis, no significant effect on income can be observed since revenues and costs tend to cancel each other.

  • Ever since the Industrial Revolution, industrial activities have been accompanied by a problem: industrial waste. The commensurate increase in industrialization, urbanization and population growth are leading to production of enormous quantities of industrial wastes that may cause degradation in environment and health hazards. On the other hand, the desire for a healthy environment increases, which leads to the need for better ways of waste minimization, pollution prevention and better use of resources in achieving the required industrial and environmental standards....

  • The quantity and the quality of the illumination are aspects that you should pay utmost attention to as far as the choice of your future projection system is concerned. Different projector models are available depending on the maximum screen widths they can be used for and, consequently, the type of lamps they use. Please bear in mind that if you would like to screen in 3D, a change in the lamp power must be possible. This point will be addressed in § “3D“. The related choices affect above all the environment of the projector and the way to operate it. These...

  • Well‑managed water systems are a fundamental policy goal for all countries and can be an important driver for green growth. Yet significant gaps persist between aspirations to ensure access to sufficient and sustainable quantities of good quality water and the actual conditions on the ground. Identifying appropriate policies and approaches for good water policy is only a first step - implementation is essential.

  • In the United States industry is the greatest source of pollution, accounting for more than half the volume of all water pollution and for the most deadly pollutants. Some 370,000 manufacturing facilities use huge quantities of freshwater to carry away wastes of many kinds. The waste-bearing water, or effluent, is discharged into streams, lakes, or oceans, which in turn disperse the polluting substances. In its National Water Quality Inventory, reported to Congress in 1996, the U.S.

  • The chemistry of fine organic intermediates and products shows an enormous diversity. But in reality, the number of operations/processes used remains reasonably small. These include charging/discharging of reactants and solvents, inertisation, reactions, crystallisations, phase separations, filtrations, distillation, product washing. In many cases cooling, heating, or the application of vacuum or pressure is necessary. The unavoidable waste streams are treated in recovery/abatement systems or disposed of as waste.

  • Wastes are very process-specific but the key pollutants can be derived from knowledge of: the process, construction materials, corrosion / erosion mechanisms and maintenance materials. Waste audits are used to gather information on the source, composition, quantity and variability of all wastes. Waste prevention typically involves preventing the arising of waste at source, minimising the arisings and recycling any waste that is generated.

  • The objective of waste water treatment is to prevent large quantities of substances to reach and impact the environment in high doses and concentrations. Areas of high population densitiy naturally are areas were production of sewage sludge is high (see Figure 1-1). Presently about 8 million t of sewage sludges (MAGOAROU 2000) are produced each year in the EU member states (Table 1-1). Its high content of organic materials, of nitrogen and phosphorous suggest their use as soil conditioner and fertilizer in agriculture.

  • A further example of process redesign for manufacturability is Boeing’s Point of Use system for chemical materials. This enables the storage of materials where the production process utilizes them, as opposed to the previous system which utilized centralized chemical disbursement centers that entailed frequent machinist travel over substantial distances and greater overall chemical usage and waste. Generally, point of use efforts enable the storage of materials where the production process utilizes them.

  • Freshwater sources and oceans have an amazing natural ability to break down some waste materials, but not in the quantities discarded by today' s society. The overload that results eventually puts the ecosystem out of balance. Sometimes nature itself can create these imbalances. But most often our waterways are being polluted by municipal, agricultural and industrial wastes, including many toxic synthetic chemicals which cannot be broken down at all by natural processes.
