While assessing many different aspects of contamination by heavy metals and arsenic in sediments, the natural variability in element contents which depends on the grain-size and mineralogical composition of sediments, needs to be taken into account. In previous studies, the normalization of element contents to a reference element such as Al was commonly applied to compensate for granulometric and mineralogical effects. In the present study, through the investigation on the contamination of heavy metals and arsenic in sediments near Haiphong Harbor, the necessity of the normalization towards Al is assessed.
These guidelines aim to provide a framework for preventing recycling-related plastic and pellet losses, and environmental leakage. The guidelines are useful for a broad spectrum of stakeholders, particularly policymakers and key plastic recycling actors, including informal waste pickers, junkshops, consolidators, and plastic recycling craft villages. The application of these guidelines is expected to contribute to improving production efficiency in the plastic recycling chain while preventing plastic leakage into the environment.
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.
