Environmental Outcome

Malaysia has rapidly modernized, with most of the population now residing in cities and the remainder in rural or remote areas. The amount of municipal solid waste generated has increased in tandem with the country's rapid urbanization in response to that statement. Due to a lack of connectivity in rural areas, there may be insufficient infrastructure for a proper waste management system. As a result, illegal waste dumping was common, and landfills' massive volumes of waste may contribute to greenhouse gas emissions. The Malaysian government has responded by taking the necessary steps to upgrade the country's current waste management system in order to better manage municipal solid waste disposal. This research looks at how energy recovery from accumulated waste can be used as a renewable energy source, as well as the current issues, challenges, and proposed solutions. Methane gas produced as a byproduct of waste decomposition in landfills or disposal sites was used to generate electricity more efficiently and sustainably, resulting in a positive economic and environmental outcome.

Solid Waste Management System

<p class="Default">Due to rapid urbanization, ever increasing population, limited resources and industrialization all-inclusive, the environmentally habitual management of municipal solid waste has become a global challenge.  According to report of the National Population Census 2011, growth rate of Nepalese Population is 1.4 percent per annum with population density estimated at 181 per sq. KMs. Solid waste management inNepal, the current practice of the illegal dumping of solid waste on the river banks has created a serious environmental and public health problem. The focus of this study was to carry out the magnitude of the present SWM problems by identifying the sources, types, quantities, dangers and opportunities they pose. It will be helpful to examine the adequacy of the existing institutional arrangements and implement a strategic and operational plan for SWM and to establish the EASEWASTE data base of municipal solid waste management system inKathmandu City,Nepal. </p><p class="Default"><em>Journal of Advanced College of Engineering and Management, Vol. 1, 2015,</em> pp. 97-106</p>

Abstract Production of refuse derived fuel from municipal solid waste in future shall play a strategic role in an integrated waste management system. The amount of landfilled biodegradable materials thus will be diminished according to provisions of the 1999 Waste Landfill Directive. The aim of this article is to evaluate cost effectiveness based on cost evaluation of the different complication of the waste pre-treatment equipment complectation and based on regenerable waste quantities in Latvia. The comparison of cost estimates is done in 3 scenarios considering potential waste quantities in Latvia: Scenario I - planned annual waste quantity is 20 kT; Scenario II - 40 kT and Scenario III - 160 kT. An increase in amount of waste and processing capacity means the decrease in costs of mechanical pre-treatment of 1 ton of waste. Thus, costs of mechanical sorting line under different scenarios with capacities of 10 t h-1, 20 t h-1 and 80 t h-1 are EUR 32 per t, EUR 24 per t and EUR 15 per t, respectively. Most feasible cost for a set of mechanical pre-treatment equipment for the capacity of 10 t h-1 is EUR 32 per t by using rotating drum screener with the following manual sorting. Mechanical pre-treatment equipment of unsorted municipal waste is economically nonbeneficial, when the use of fine (biologically degradable) fraction is not possible. As the sorting of biodegradable kitchen waste is not developed under the current waste management system in Latvia, the lines for mechanical pre-treatment of household waste would be better to install in landfills.

Scenario Approach

The article deals with the management of municipal solid waste in accordance with the reform. It is proved that the waste processing industry needs fundamental changes. It is proved that the effectiveness of the reform of the municipal solid waste management system can be assessed using an optimal financing model based on a scenario approach.
