Many areas in the world face clean water scarcity problems and phosphorus reserves are likely to be depleted in the near future. Still, a large amount of clean water is used to transport excreta through sewer systems. Most of the wastewater generated worldwide is discharged untreated into aquatic systems and leads to water pollution and loss of valuable nutrients. In Hanoi, Vietnam's capital city, high population and economic growth as well as industrialisation have led to a decrease in groundwater level and to serious river and lake pollution. A probabilistic model, simulating the impact of measures on groundwater abstraction and nutrient recovery, was used to determine the impact of policy changes in Hanoi. The results obtained reveal that harmonising environmental sanitation and agricultural systems with one another will considerably increase nutrient recovery for food production, lower expenditure for artificial fertilisers and reduce the nutrient load into the environment. The model can be applied in urban areas of developing countries to assist in the design of environmental sanitation concepts.
The manual aim to support both formal and informal recycling enterprises in preventing plastic pollution by advocating best practices and promoting proper housekeeping within informal recycling facilities.
The main goal of this study is to evaluate plastic and pellet losses and leakage from the logistical handling and pre-processing operations of informal recycling groups in Thailand, focusing on recovered post-consumer plastic waste and factory processing operations. The focus areas of this study are the Nonthaburi Municipality and Pattaya City.
This study was conducted following on a simplified three-step approach: 1) collect and analyse data and information relevant to plastic leakage from informal sector recycling; 2) engage with key stakeholders; and 3) disseminate the outcomes of the study.
Situation Assessment Report on Plastic Leakage Prevention from Formal and Informal Recycling Facilities, Maninla City and Iloilo City - Philippines
Situation Assessment Report on the Prevention of Plastic and Resin Pellet Leakage from Formal and Informal Recycing Factories, Hanoi - Vietnam
The guidelines aim to fill knowledge gaps and promote contextually appropriate best practices. They will also encourage industry actors to implement measures to prevent and contain plastic and pellet leakages. Based on the findings of a preliminary assessment of the post-consumer plastic recycling value chain, which analyzed primary sources of plastic loss and leakage, including technology applications, resource availability, access, and regulatory and policy gaps, these guidelines are designed.
