A Study of Societal Flow of Phosphorus and Its Effect on Environmental Sustainability In Landfill Sites Terengganu, Malaysia

Abstract

Phosphorus (P) in the waste at Terengganu can be identified by the heterogeneity of waste sources present at the waste disposal collected, the technology used, location of disposal and the management depends on microbial waste decomposition operations. The diversion of phosphorus out of the waste disposal sites is associated with the presence of low phosphorus inflows due to reduction, recycling and waste recovery activities outside of the landfill system. This finding motivates the socioeconomic characterization of the actors (players) and the identification of management strategies developed by the stakeholders. Thus, the purpose of this study was to identify the nutrient element of phosphorus in the waste disposal site and investigate whether stakeholders were aware of phosphorus and phosphorus credit related to local economic circulars and to examine possible ways of managing phosphorus in the waste source by small waste players in Terengganu. The design of this study was qualitative, involving face-to-face interviews with the stakeholders and a corresponding analysis of their responses. The findings revealed lack of knowledge and awareness by actors regarding the element phosphorus, the causes and sources of phosphorus generation as well as the effects of phosphorus on environmental sustainability. This study highlights useful factors to guide future management decisions and educational programs as well as further research, to disseminate information concerning phosphorus recovery among actors involved in waste management at Terengganu.

Microplastics in Malaysia's Aquatic Environment: Current Overview and Future Perspectives

“…[ 47 , 50 ] Eastern states of peninsular Malaysia, mainly Terengganu, Kelantan, and Pahang, contribute much plastic waste, generating 0.71 kg/capita/day. [ 51 ] Certain activities, namely agricultural, industrial, tourism, fishing, and urban areas are the main factors contributing to plastic waste pollution. [ 52 ] Application of biosolids and compost, wastewater irrigation, mulching film, polymer‐based fertilizers, and atmospheric deposition are the main sources of microplastic pollution in agricultural soils.…”

Environmental investment: the most adequate neo-industrial response to the growth dilemma of the economy

“…Obviously, the goals of such investment will differ from that of traditional capital investments (increasing labor productivity). Ecological investments should be oriented toward transformation of the current economy into a green (circular) one, and toward achieving strong sustainability (Arkhipov et al, 2018;Ghani et al, 2019;Aziz et al, 2019…”
