In their activities, humans produce a large amount of wastes. A sharp increase in consumption resulted in a large volume of solid domestic wastes, which must be combated. All this poses a certain life threat to mankind. However, there is no totally waste-free production. That is why the most effective way of waste disposal should be chosen. That is why it is necessary to choose the most effective way of waste utilization with minimization of environmental and economic risks.

Brick debris that makes up the majority of construction waste has not received proper waste disposal in Indonesia. On the other hand, brick debris could be potentially reused as non-structural building materials to reduce its negative impact on the environment. This study aims to test the effectiveness of soundproofing on recycled brick debris. The soundproof test was carried out on brick debris in the form of fine and coarse grains. The simulation box is then used as a support for the brickwork material and then the box is exposed to a sound source with a certain level of noise that is considered disturbing human comfort. Noise level measurements are made in the outside and inside the box. These measurements are tabulated and then analyzed to see the success of the two aggregates in reducing noise. Basically, the brickwork material has succeeded in becoming a recycled building material that can absorb noise, although further research must be carried out to be able to state that this material is truly ready to be used as an alternative building material with good acoustic capabilities.

Abstract The concent rat ions of hexachloroethane (HCE), hexachlorobutadiene (HCBD), pentachlorobenzene (QCB), hexachlorobenzene (HCB) and octachlorostyrene (OCS) in large volume water samples show that the major sources of these chemicals to the St. Clair River are Dow Chemical Company effluents and, to a lesser degree, Sarnia’s Township ditch which drains one of Dow’s waste disposal sites. Tributaries entering the river on both sides of the Canada/United States border contain measurable concentrations of these chemicals indicating low level contamination throughout the area. The degree of water/suspended sediment partitioning of the chemicals (Kp) was studied. Kp values for the individual chemicals changed in a manner consistent with changes in their physical-chemical properties.

The management of municipal solid waste (MSW) appears to be one of the major ecological problems at present. Selecting sites for the disposal of municipal solid wastes or waste utilization facilities is one of the most contentious aspects of waste management. The present study aimed to develop the methodology to assess the natural protection of the geological environment from contamination upon the implementation of large ecological projects due to the allocation of MSW utilization facilities. The case of the Central Federal District of Russia (CFD) is taken as an example. The suitability of territories for municipal solid waste disposal is assessed according to the presence of weakly permeable deposits in the geological cross-section and their occurrence mode. A “map of engineering geological zoning CFD by the conditions of allocation MSW disposal sites and utilization facilities” has been compiled to a scale 1:2500000. The map gives a general indication of the suitability of the planned sites for waste disposal within the regarded region and showed that, for the bulk of territory, the allocation of MSW disposal and management facilities requires undertaking additional measures for the geoenvironmental protection from contamination.

Construction waste is the most important source for reducing raw material resources. In this regard, many countries conduct large-scale research in developing progressive construction waste utilization technologies and creating highly efficient production equipment. Current experience in this field views the construction waste processing system as a number of interconnected subsystems: organizational and technical preparatory measures; waste collection and sorting; waste containerization, packaging and transportation; waste processing and manufacturing of recyclable resources. Each sub-system consists of a set of measures which characterize the change in material quality and properties. Modeling of the construction waste processing system addresses the task of assessing the actual level of the system and subsystems and determining the condition of the same within certain forecasted time perspectives. For this purpose, the cost vs. revenue comparison tools are used. To develop the construction waste processing system and maintain it in working condition it is important that, early on in the project, a waste classification catalogue and a relevant glossary of terms be compiled with all waste processing contractors having to agree to it and observe it. Also, a data bank containing all the relevant engineering and process documentation shall be drafted and maintained

It is a necessary step to break bags for bagged domestic waste before crushing it. This thesis carried out kinematic analysis for Whitworth mechanism, and put forward the requirements of shape of tool on account of the problem that materials (garbage) winded tools, In addition, it briefly discussed the design of avoidance device by Theory of Inventive Problem Solving (TRIZ). Preface Domestic waste refers to the solid waste generated in people’s daily lives. In recent years, with further urbanization, and the growth of population, domestic waste has been in sharp increase, so rational treatment of garbage has become a national sustainable development strategies related to the important issue. The main methods of waste disposal at this stage are landfilling, composting, incineration, of which landfilling is the most important. The level of domestic waste processing has a great gap between at home and abroad. As the processing technology has been started in Europe and other developed countries, thus, it is relatively mature, and the sense of residents’ environmental protection is stronger, the difficulty of waste disposal is reduced, so that the problems of waste disposal have been solved better. The research of waste disposal in China began in the 1980’s,and waste is bagged in the main form of garbage collection at present. On grouping garbage is so complicated and the equipments used to dispose garbage are insufficient, which can not meet the standards of waste reduction, innocuity and reclamation required by the government. At present, the garbage crushing equipment used in China is prone to twist, less efficient, poorly noisy, and adapt to different waste. Besides, it is easily over-fragment the unbreakable material such as glasses and used batteries, causing second pollution. Consequently, to develop new equipment for bagged domestic waste is of top priority.

The purpose of this study is to analyze CO2 emission based on computation of construction waste which occurs during new constructions. To accomplish the purpose, Basic unit data of existing construction wastes was analyzed and basic unit of construction wastes generated during new constructions was proposed. In addition, basic unit of CO2 in the disposal process of construction waste established as the national LCI DB of Korea was applied to analyze CO2 emission during the disposal process of waste (landfill, incineration, recycling) generated during new constructions. As a result, flammable materials showed relatively high emission of 17.75kg-CO2/kg and 2.40kg-CO2/kg for the landfill process and recycling process, and inflammable materials had high emission of 0.74kg-CO2/kg for the incineration process. As a result of analysis for each waste, emission was found to be in decreasing order of landfill and recycling processes for concrete, recycling, landfill and incineration processes for metals, incineration, recycling and landfill processes for wood and flammable materials, and landfill, recycling and incineration processes for inflammable materials.
