Increasing solid waste is one of the most crucial environmental problems in Malaysia. Improper management of solid waste will cause many problems. Increasing solid waste, lack of segregation from the source, and lack of knowledge and awareness about recycling have only worsened the problem. Knowledge of solid waste generation and composition is necessary for accurate decision making in the management strategy of municipal solid waste. The objectives of this study were to measure solid waste generation and analyse and compare the composition of solid waste in two different cafés at Universiti Putra Malaysia. Solid waste samples were collected every day except for Saturdays and Sundays over a three-week period and were sorted and classified into several weighed compositions such as food waste, plastic, paper, aluminium cans, glass, metal, textiles, wood, and more. Results showed that total municipal solid waste generated during three weeks of sampling at Forestry café and Park View café were 325.75 kg, or an average of 21.72 kg/day, and 2979.70 kg, or 198.65 kg/day, respectively. There is significant difference in data collection between the two locations. From the result, it shows that organic waste was the main component in municipal solid waste composition for both cafés, where it is 81% for Forestry Café and 96% for Park View Café, followed by the other compositions. The high organic waste indicates the necessity for frequent collection and removal, as well as having a good prospect for organic waste recycling through composting. Based on this information, a proper waste management system can be introduced to treat the solid waste more efficiently.

Malaysia is faced with daunting challenges related to solid waste management. Due to an increase in population, economic growth, inadequate enforcement of waste legislation, infrastructure, and public attitude among others, solid waste management is considered a crucial issue in Malaysia, particularly in urban settings. This paper gives an overview of solid waste management in Malaysian with the aim of presenting the state of waste generation, composition, management practices, and problems with regards to environmental, economic, and other ramifications from previous records. In general, the total waste generated in Malaysia is estimated to be 7 million tons in 2000, with an annual increase of 3%. This is due to many factors such as urban migration, affluence, and rapid development. This circumstance requires greater focus to be in placed on managing solid waste and mitigating the negative public and environmental effects. Presently, management of solid waste is carried out by the Ministry of Housing and local government, with the support of the private sector. This new holistic approach initiated addressing the solid waste issue, taking into account public health and environmental concerns with an emphasis on reduction, reuse, and recycling before reaching final stage – disposal at landfill, and this to certain extent has a greater potential in addressing SWM problems in Malaysia.

Population pressure and land use activities in urban areas are deteriorating the health of ecologically rich tropical rivers. Despite various programs and enforcement carried out by government agencies, most river conservation projects are not sustained according to the expected objectives. Much of the blame is due to lack of public environmental awareness and participation. However, there is a lack of adequate local field data to explain this scenario. This case study was specifically conducted to evaluate the local public perception and willingness to participate on a river conservation project of an urbanized Temiang River watershed located in Peninsular Malaysia. This survey was carried out on 200 randomly selected respondents. Contrary to blame, results indicated that awareness was not the major issue; instead, it is their voluntary involvement in protecting the river. Overall, the respondents show a high willingness to be involved in the conservation program. However, factors of age, educational background, gender, income level, marital status, and residential locations determine the level of their willingness to participate.

Manufacturing industries in Malaysia play a fundamental role in economic growth and enhancing the population’s standard of living. However, a huge quantity of industrial wastes is generated daily, exacerbating landfill disposal issues. Waste minimization as the most sustainable approach of waste handling contributes to a significant reduction of waste. In Malaysia, practicing waste minimization by manufacturing firms is not very common. Thus, this study attempted to determine the most commonly practiced methods of minimization by manufacturing firms in Malaysia. Also, the effectiveness of each method in waste reduction was explored. Data were collected through survey and analyzed through the quantitative and qualitative approaches from 214 manufacturing firms that cover small, medium, and large sizes with a 67.5% response rate. The questionnaire was developed based on the review of literature and is validated by a panel of experts. Paired sample T-test was used to compare the solid waste generation one year before and one year after practicing methods. Spearman Rho Correlation and multiple linear regression analysis were used to explore the relationships of methods and their significant contribution in waste reduction. Findings revealed that waste generation was significantly different after practicing waste minimization methods (p<0.05). With respect to the methods correlation and effectiveness in waste reduction, all waste minimization methods have a significant and positive correlation with waste reduction (p<0.05). Methods include segregation of wastes, on-site reuse and recycle, improved housekeeping, and equipment modification – all of which were found to be effective in waste reduction for Malaysian manufacturing firms (p<0.05).
