Solid waste burden

Plastics are a significantly larger fraction of municipal solid waste by volume than they are by weight. Is it more accurate to look at the solid waste burden by weight or by volume Why ... 

A common classification of categories is according to their role in resource depletion, pollution or damage (Table 4.2). Energy production is often presented as Gross Energy Requirement (GER), while waste production is represented by a Solid Waste Burden (SWB). 

Thermosetting plastics offer many advsuitages in end-use properties for high-performance applications (6.7). They suffer from greater difficulty in processing, and from the low utility of manufacturing scrap, which therefore becomes solid waste, and constitutes a double econcanic burden. The scrap can of... 

Solid waste discharges from chemical plants can represent very large problems, especially from paper mills, plastics plants, and food processing plants. Some materials do not decompose in the environment, and can become burdens when they accumulate. Some polymers have backbones that degrade in nature, such as aliphatic polyesters and polyvinyl alcohols others do not, such as polyethylene and polystyrene. 

In summary, solid waste gasification is ahereand now technology for industry s profitable use. Using a process developed over a century ago and applying today s method and materials, we are able to relieve the burden placed on our landfills and produce additional income through an environmentally acceptable process. 

Because the only purpose of size enlargement in this category is to render solid wastes suitable for safe disposal, the cost for the processes is an add-on burden and, consequently, must be kept low. Therefore, typically, the cheapest method will be chosen which often comprises, for example, only the mixing of waste with cement and water and forming crude brick-like bodies that harden into disposable, inert pieces. Depending on the hazardous level, more and more sophisticated (and expensive) solutions may have to be chosen which can finally include some sort of additional sealing by surface coating or... 

Table 5 illustrates the grouping of effluents and emissions to water, air, and solid waste. 2 ft is important to note that the mass in these categories cannot be simply added to produce a meaningful environmental index because some are associated with much more significant environmental impacts than others. The process of converting all of these outputs to useful burden index measures is a part of the inventory assessment process. 

Universal waste rule was an amendment to the Resource Conservation and Recovery Act regulations. It is designed to reduce the amount of hazardous waste items in the municipal solid waste stream. The rule encourages the recycling of certain common hazardous wastes and their proper disposal. Another objective of this rule is to reduce paperwork and other administrative requirements and regulatory burden on businesses that generate these wastes, and to save them compliance costs.

Processes such as pyrolysis and combustion reduce the volume of solid wastes and, in particular, plastics waste. Solving the problem of the vast volume of plastics waste is often the key to successful solid waste management. Low-density polymers such PE, PP and so on, require costly storage at the point of waste generation, which greatly affects the cost and the logistics of collection and handling. Incineration is an attractive process to decrease not only the volume of solid waste but also reduce the burden on landfill and other disposal operations. Incineration is not a final disposal method as it requires landfill or other means to receive the solid residues. 

The breached tailings pond at the gold mine, which was 93 ha in area and about 20 m deep, was lined with a plastic membrane and held approximately 4.43 million tons of flotation solid wastes. Due to an imbalance between water burden, unexpected quantities of water from the addition of snow and rain, and safe storage volume, the capacity of the pond was insufficient to safely store the slimes. It was estimated that 50 to 100 tons of cyanide were released into the river (UNEP/OCHA, 2000). 

Most kinds of waste now being produced carry a burden of metal contamination and it is evident that the primary step associated with the dispersion of trace elements in the environment is usually the disposal of some kind of waste. This can take the form of gases or particulate matter discharged into the atmosphere, substances dissolved or suspended in liquid effluents, or solid wastes. The disposal of the various kinds of wastes produced can therefore give rise to pollution of the atmosphere, or of rivers, lakes, estuaries and coastal waters, or of the exposed soil surface. The whole biosphere is affected.
