Growth of the population and of industrialization, and substandard disposal of the increased waste products thus generated, have resulted in numerous documented cases of harm to human, plant, and animal health. The Resource Conservation and Recovery Act (1976), its stated goals, and its intended means of implementation, are discussed relative to hazardous waste problems. Subtitle C of this Act,...

Research in chemical engineering requires experiments, which are often expensive, time-consuming, and laborious. Design of experiments (DoE) aims to extract maximal information from a minimum number experiments. The combination DoE with machine learning leads the field active learning, results more flexible, multi-dimensional selection Active has not yet been applied reaction modeling, as most ...

This paper begins by providing an outline of various waste stabilisation techniques on which the concept of bioreactor or process-based landfills is based, followed by an overview of the research and development of this alternative landfill approach. The paper then presents a summary of the Australian experience. It also reports on the current state of bioreactor landfills and discusses the dif...

objective: dental solid wastes often contain hazardous substances. the first step of management of dental solid wastes includes detection and classification of these substances. this study aimed to qualitatively and quantitatively assess the management of solid wastes by dental offices in urmia city in 2013. methods: this descriptive study was conducted on all private dental offices in urmia ci...

Solid waste is a significant and growing problem in many urban areas of the developing world. Current systems of waste management in most developing country cities are very rudimentary at best and are grossly inefficient and ineffective. Uncontrolled landfill disposal of solid waste is a pervasive problem which causes a range of external costs, including human health hazards. This paper sets ou...

Solid waste management practices itself is far from satisfactory, in India. Added to the above, is another problem of recent origin i.e. E-waste handling and management which has complicated waste management due to their unique properties than other solid wastes. The generation, separation, recycling and recovery of precious metals are still in its nascent state, almost all over India. In order...

Moving toward a sustainable industrial activity requires an effective waste management that is applicable and efficient for all different types of industrial wastes .Waste minimization as the most acceptable option in waste management hierarchy, has a significant contribution in minimizing the solid wastes generated by manufacturing industries. The absence of appropriate policy, lack of awarene...

There is a concern that mismanagement of medical waste in developing countries may be a significant risk factor for disease transmission. Quantitative estimation of medical waste generation is needed to estimate the potential risk and as a basis for any waste management plan. Dhaka City, the capital of Bangladesh, is an example of a major city in a developing country where there has been no rig...

A modelling methodology using a leachate source term has been produced for estimating the timescales for achieving environmental equilibrium status for landfilled waste. Results are reported as the period of active management required for modelled scenarios of non-flushed and flushed sites for a range of pre-filling treatments. The base scenario against which results were evaluated was raw muni...

from the sago palm is the starchy fibrous pith residue. This residue is abundantly and cheaply available especially in the state of Sarawak, Malaysia. It is usually washed off into drains or nearby streams together with wastewater, thus contributing to pollution load, or deposited in the factory’s compound, which can lead to serious environmental problems. It has no significant industrial or co...
