“…The current method of packaging waste disposal is landfill, followed by recycling, incineration, and composting. However, landfilling contributes to emitting greenhouse gas and may contaminate land that could be used in the future (Michel Devadoss et al., 2021). Retaining plastic industries in a circular economy would save the cost, time, energy of manufacturing and encourage innovation from used items while reducing dependence on new plastic manufacturing (Korhonen et al., 2018).…”

The application of petroleum-based plastic worldwide causes the accumulation of plastic waste in landfills, which negatively impacts the environment such as reducing the quality of soil and may cause soil and water pollution. Most of the conventional plastics used have a long lifespan to completely degrade. According to the rapid development of the food industry, plastic packaging plays a key role in food quality and safety, thus making it a major role in controlling the food security system. The alternative use of plastic sources from biopolymers is one of the methods to support environmental sustainability actions. This review provides an overview of studies on principles and challenges of sustainable packaging including different types of biopolymer compounds properties and biodegradability of bioplastics in soil by microorganisms. The biopolymers composition in biodegradable plastic is important in designing better mechanical, physical, and barrier properties during degradation by microorganisms and application in food industries.

“…In order to combat this issue, most of the countries approach renewable energy as a replacement for fossil fuel to fulfil the energy demand. In Malaysia, the energy sector and waste sector contribute to 80% and 9% of the GHG emission respectively [6].…”

The elevation of waste generation subsequent to population growth has become a severe environmental topic in Malaysia. Since most of the waste is being dumped into a landfill, the open dumpsite, or unsanitary landfills which are not constructed with proper engineering plan, severe impacts on the environment result. The energy demand in Malaysia increased with the growing population, but reliance on fossil fuels to generate electricity has created another greenhouse gas contributor. Alternatively, waste-to-energy technology solves the problem of increasing waste by converting the waste to a renewable energy source. Malaysia has moved towards landfill gas recovery system and incineration for waste energy recovery. The recovery system and refuse-derived fuel plant achieved expectation; however, the incineration plants have failed due to the opposition of the public, lack of funding and technician expertise, and other technical issues. The solid waste management practices lacking separation and recycling sources, become an obstacle for development. The government puts effort into solving the current issue by promoting recycling in the public, enforcing the legislation, and approaching new technologies for better solid waste management practice in the future. This paper aims to discuss the application of energy recovery from municipal solid waste in Malaysia.

“…Malaysia is a developing country located in Southeast Asia, with a population that is approximately 32 million [6] and a total area of 329,847 km 2 [6]. The country is divided into two parts that are separated by the South China Sea, one part being Peninsular Malaysia, which borders Thailand and Singapore, while the other part is located on Borneo Island and borders Kalimantan (Indonesia).…”

Sustainable urban development is a major issue in developing countries, namely in environmental and social aspects. Urban forests have the potential to address these issues. Thus, it is not surprising that urban forest research is slowly gaining traction in these regions. However, there have been limited urban forest research reviews focusing on developing countries, especially tropical countries in the global south. Research reviews are vital in identifying the distribution of research themes, hence revealing research gaps and needs. Therefore, this review paper aims to provide a deep insight into the development of urban forest research in Malaysia in the past 20 years. The core purpose of this review is to analyze the distribution of research themes in Malaysia, thus identifying research gaps and needs in developing countries. A total of 43 articles were selected for this review, using the PRISMA framework. The distribution of research articles showed a continuous increase over time, especially for the past five years (2016 to 2021). The reviewed articles were categorized according to five emerging research themes in urban forestry. More than 41% of the reviewed articles fell under Theme 1 (the physicality of urban forests), with the majority being on biodiversity (n = 10). Theme 5 (the governance of urban forest) had the lowest research output (n = 3). Urban forestry research is slowly gaining prominence globally including the global south; however, there are obvious preferences in research focus, causing some research questions to be neglected. These research gaps are especially evident in four areas—soil science, ecophysiology, valuation (economics), and environmental justice. These research gaps should be addressed by the scientific community to ensure a thorough and complete research growth pertaining to urban forestry.
