“…All of the states are located in peninsular Malaysia. It covers an area of 130598 km 2 (50424 sq mi) and had an estimated population of 1.73 million as of 2016 [9]. It is located at coordinates 4°00'0.00" N, 102° 29' 59.99" E. The Department of Statistics Malaysia reported that the estimated population in first quarter of 2019 was 32.66 million, 32.385 million in 2018 and 32.022 million in 2017 and an increase approximately 1-2% annually [10].…”

“…In Malaysia, it is estimated that the amount of recyclable materials thrown to the garbage disposal site annually is 2.3 million tons with an estimated value of RM900 million. In 2013, the country's total waste generation increased to 33,000 ton per day, compared to 19,000 ton per day in 2005 [3], [4], [9]. This means that the average annual solid state increase in solid waste is linearly 6.7 per cent, which is significantly higher than the average rate of increase at the international level of 3 per cent only.…”

Solid waste management gained the highest significant attention globally. In Malaysia, the generation of solid waste has increased 4% approximately year by year and an average from 0.8 kg/cap/day to 1.12 kg/cap/day. This trend is in line with the increasing population density in Malaysia especially in urban areas. The exponential growth of economic, urbanization, demographics and changing lifestyles are the key reasons behind the increase in the generation of solid waste. The objective of this research is to develop a system dynamic model for solid waste management in peninsular Malaysia and analyze the recycle evaluation. This method has an ability to handle a complex system and dynamic behavior over time. The result show that model imitate the real system with the validation less than +10% and -10% of acceptance range. This model can assist the decision maker in making efficient decision. The management of solid waste department may holistically measure the alternative action in cost effective and save time. As a result, the recycle rate in Malaysia relatively low and lack of participation from public. Enforcement and engagement from all parties are needed in order to achieve a sustainable environment in future.

“…The increasing trend in waste generation annually gives an impact towards sustainability of the environment. These due to changes in life styles, income level, urbanization process and increment in the population rate [1][2]. The waste generation rises approximately three to four percent every year based on the population rate.…”

The study is focusing on the environmental care components in solid waste management among students at UiTM Campus Tapah. This study is conducted through a questionnaire and involved a total of 354 students. The environment care components are consisting of knowledge, practice, attitude, perception and awareness. Statistical analysis of mean score and t-test are conducted in order to analyze the data collected. The results of the survey are highlighted that majority of the UiTM Tapah students had high knowledge level towards environmental care; and had very good practice in environment cleanliness; had a moderate concern on attitude, and the majority of the students had moderate perception in term of understanding and practicing solid waste separation and finally majority of students know their personal accountability towards environment care based on awareness component. As a conclusion, environmental care among students shows positive responses in Awareness, Practice, Attitude, Knowledge and Perception towards sustainable solid waste management in future.

“…Experiencing rapid increase on the population and urbanization process reflects the increasing waste generated [5]. Abundant of solid waste generation from our daily activities has risked for our communities [22]. Based on Malaysian statistics, the data show that the Malaysian population especially in urban areas has dramatically increased to more than 50% for the last few decades [17] .…”

Solid waste management is considered as one of the complex and dynamics problems worldwide due to rapid population, changing life style, urbanization process towards sustainable development and uncontrollable increment in solid waste generation. An efficient performance of solid waste management is depending on systematic strategic planning. The aim of this paper is to develop an integrated dynamical model to simulate the complexity of solid waste management in Malaysia. System dynamics as one of optimization methodology is applied in order to illustrate the continuous process in solid waste management Malaysia. As a result, an increasing trend of solid waste generation over time. By 2025, it is forecasted that total waste will be more than 15 million tonnes. Based on developed proposed model, the main factor to solid waste generation is population. However, in order to reduce the total solid waste, we cannot simply reduce the population Therefore; further actions are needed in order to reduce the total solid waste generation. The proposed model is capable of assisting the decision maker to determine the effectiveness of solid waste management practices especially in strategies planning and system design improvement.
