Kuala Lumpur, Although it has made progress in some areas, Malaysia's daily waste generation rate remains well above the global average.

Disposal of Malaysia's domestic and imported waste is a growing concern.

Malaysia's total household waste generation has been trending upwards, increasing from 36,500 tonnes per day in 2015 to 38,150 tonnes in 2018, while the estimated waste generation rate for Malaysia is 1.17 kg per capita per day, of which 65 percent is domestic. solid waste. This is much higher than the worldwide average of 0.74 kg. By category, Malaysia wastes about 16,720 tonnes of food every day, which is 44 percent of its total waste generated.Furthermore, Malaysia faces increasing challenges in managing imported waste that comes under the pretext of 'recycling'. In 2021, Malaysia imported more than 500 thousand tonnes of plastic waste and exported about 11 thousand tonnes, making the country one of the major importers of plastic waste globally.

The increase was the result of China's ban on imports of most plastics and other materials in 2018. China's decision disrupted the global plastics recycling industry by diverting waste shipments to developing economies in Southeast Asia, including Malaysia. Although ASEAN countries account for less than nine percent of the world's population, ASEAN countries are expected to account for the world's largest share of plastic waste from 2017 to 2021. Received 17 percent of plastic waste imports.Malaysia has become a dumping ground because these imports include mixed plastic waste and non-recyclable plastic waste – plastic waste that is substantially contaminated with other waste or contaminated with toxic additives that make recycling impossible.

Nevertheless, recycling of used plastics has been promoted as both a business and a waste management solution as part of the circular economy in the developed world, relying on the reuse of materials to promote sustainability. Studies show that improper management of waste streams – both domestic and imported – poses significant risks to human health and the environment.

Mismanagement of waste results in inefficient use of resources and hinders recycling efforts, thereby contributing to resource depletion and unsustainable practices.

Solid waste is made up of non-liquid waste, such as garbage and waste generated from domestic, commercial, trade and industry, agriculture and construction and demolition and mining activities.In further classification the waste is classified on the basis of biodegradable or non-biodegradable. Flammability and non-combustibility and hazardous or non-hazardous. The challenges in solid waste management are to 'prevent, dispose and reduce' negative impacts on human health and the environment without compromising economic growth potential.

Landfills are still the primary method of solid waste management in Malaysia, with the remaining waste being either incinerated (26.5 percent) or recycled (17.5 percent).

As waste generation is expected to increase from 468 million tonnes per year in 2016 to 714 million tonnes per year by 2050, sanitary landfills in Malaysia are nearing capacity.The lack of accurate and comprehensive data on the type and quantity of waste imported into Malaysia makes it difficult for authorities to assess the risks associated with cross-border waste importation, in addition to locally generated waste.

Researchers in Malaysia had said that the solid waste recycling rate will reach 31.67 percent in 2021, not even close to the 40 percent projected by 2025. Meeting the target requires investment in infrastructure and resources to handle waste flows while focusing on information and studies on solid waste. Recovery and Recycling.

Specific issues of solid waste management in Malaysia include low collection coverage and irregular collection services and open dumping and burning.The country also faces challenges such as illegal dumping, questionable practices of some local waste management operators, lack of recycling support ecosystem and limited sanitary landfills. In Malaysia, most landfills are open dumpsites and 89 percent of the waste collected is landfilled. ends in. Disposal issues where most waste goes to landfill rather than being used as energy can be overcome by investing in waste-to-energy technologies.

These facilities convert waste into energy to help reduce landfill use and generate renewable energy. Energy recovery from biogas in landfills may represent a solution to the growing demand for solid waste treatment and renewable energy.However, the efficiency of landfill biogas recovery should be examined considering that the effect of operational factors such as coating process, gas drainage and liquid management will vary according to waste characteristics, environmental factors and technical capacity.In Malaysia Existing recycling programs have failed to increase public awareness of the importance of proper waste separation, recycling practices and reducing waste despite an increase in overall household waste generation.

Implementing comprehensive recycling initiatives and adopting a circular economy approach require strong governance instruments and buy-in from consumers.

Enforcing strict regulations on waste management practices, including penalties for illegal dumping and incentives for sustainable waste disposal methods, is also needed. On the positive side, the regulatory framework to prevent waste from being disposed of in landfills moves from linear Has shifted to circular economy.However, there is ambiguity in monitoring and enforcement mechanisms, including lack of emphasis on the recycling agenda, inadequacy in accountability of retailers, lack of enforcement on legal consequences, and delays in further improving the current regulatory framework.

In the circular economy, investment by businesses will be a key factor in financing waste management. It should complement private and public partnerships for waste disposal operators. Government support through effective financial mechanisms such as grants, loans and tax exemptions is an important part of the overall policy mix for waste management and an important part of moving towards a circular economy. Supports. This will allow the development of infrastructure such as investment in sanitary landfills and recycling infrastructure to improve waste management efficiency.(360info.org) PY
