1.0 INTRODUCTION Landfill is the disposal of waste into or onto land. Today, landfill sites are constructed and operated to strict technical standards in order to reduce environmental effects. Landfills have four types that is sanitary landfill, municipal solid waste landfills, construction and demolition waste landfills and industrial waste landfill. The Environmental Protection Agency (EPA) isrequired, under the Environmental ProtectionAgency Act, 1992 to specify and publish criteria andprocedures for the selection, management, operationand termination of use of landfill sites. In the past, many of the problems associated with landfills occurred as a result of non engineered facilities and poor management.
(2011) research, the Construction Managers need to manage numerous elements that may adversely influence the development procedure, generating distinctive sorts of wastes. There are a few reasons for material wastes which majorly rely on the kind of development techniques utilised, the particular materials being used, and/or the phase of the development itself. Researchers are on the view that waste can be produced by errors, working out of series or sequence, excess action and development, deferred or untimely inputs and items that don't address client issues and fail to meet the demand of the consumers (Tan, et al.,
In today 's modern world pollution is on of the biggest problems for the people and also the environment. Pollution problems occur when producers and consumers use their environment for dumping waste. The environment includes air, water and all the land that is surrounding us. The environment is very important as it is providing us with resources which are used to produce goods and services as well as giving us a place for living. We use that environment to transform different materials into goods to satisfy our wants.
It is relevance because there is a growing concern issues about the risk in the international business of worker exploitation or forced labor and supply chain complexity. Therefore, to manage supply chain complexity and to protect against the immoral conduct in the supply chain, it needs a transparency with the correct processes taken in place. In addition, there are some steps to ensure ethics in the supply chain. Firstly, it has to make sure all the suppliers complete the questionnaires of corporate social responsibility as a part of pre-qualification. The purpose of doing this is to help buyer organizations determine the weak points and remove any high-risk suppliers from the process.
The conflict issues can also be studied in more specific way. At the same time, participants in construction should have a pure image of conflict when handled with conflict issues in construction industry. Generally, the specific of conflict are linked to the time, cost, quality and safety in construction, which enable the parties in construction industry to have a better understanding about the construction conflict and discovered the best way to solve it or manage the conflict (Fenn & Gameson 1991; Kumaraswany, 1998). The importance of this study is to provide the method for the participants in construction to manage the construction conflict. Therefore, some of witnessed is needed and limitation from the past researched, so the need of upcoming research
The construction industry is an investment leadership profession, the government displays the strong interest regarding this. With the construction industry sign government contract, develops and the health, the transportation and the educational department correlation infrastructure. For any national prosperity, construction industry is necessary. If the development of construction industry is affected, it will occur high unemployment rate. It is because construction industry need many manpower to complete a project.
3. Literature review 3.1 Environmental Management In most cases environmental management discussions has been centered on industries such as chemicals, petrochemical, and mining. Recently managers have come to realize that a large proportion and increasing amount of environmental risk stems from nearly on every company’s supply chain. When a company makes supply chain decisions such as which supplier to buy from, whether to implement vendor managed inventory or what method of distribution to use, they implicitly accepts the waste stream generated because of the decision (Handfield et al, 2003). Increasingly companies have realized that environmental management is a key strategic issue awith the potential for a lasting impact on organizational performance.
1.) HAZARDOUS WASTE 1.1) Hazardous Waste Hazardous waste can be defined as waste that even in low concentrations, has the potential to have a significant adverse effect on the public health and the surrounding environment due to the inherent toxicological, chemical and physical characteristics that it possesses. 1.2) Handling of Hazardous Waste Hazardous waste requires stringent control and management, to prevent harm or damage and hence liabilities. It may only be disposed of in a hazardous landfill.  The ‘precautionary principle’ should always be applied, hence waste should always be regarded as Hazardous whenever there is any doubt about the potential danger the waste could pose on humans and the environment.
With its contribution to the economic development and economic activities, construction sector has a significant affect in the development of any nation. Because the construction sector is large and responsive, as well as it has a strong linkages with other industries, it is a key sector can affect economic development and, hence, it is important to know what is the role of the construction sector is in the economy. There are 5 factors that the construction sector affect in the economic development and economic activities. i. Demand for basic materials Beyond the construction activity itself, construction drives demand for building materials.
From the above paragraphs is it clear that waste is a very broad concept that is defined differently from the jurisdictions or regions around the world. Below is a brief definition of what hazardous waste is. A ‘hazardous waste’ is defined as “an inorganic element or compound that, because of its toxicological, physical, chemical or persistency properties, may exercise detrimental acute or chronic impacts on human health and the environment (DWAF, 1998). Hazardous waste can be generated from a wide range of commercial, industrial, agricultural and domestic activities and may take the form of liquid, sludge or solid. These characteristics contribute not only to degree of hazard, but are also of great importance in the ultimate choice of a safe
