Today’s pollutants, tomorrow’s potential solutions

 

Our proposed initiatives address emergent worldwide environmental problems, i.e., the increases in pollutants and organic waste generated in densely populated cities. These emerging pollutants include all toxic chemicals, among them persistent organic pollutants, endocrine-disrupting chemicals (EDCs), and emerging chemicals of concern (ECCs, such as phthalates, bisphenol A, microplastics, and nanoplastics, etc.). EDCs and ECCs, extensively used in industrial and consumer products, are a highly significant group of environmental pollutants. Due to their persistence, bioaccumulative properties, and ubiquity in the environment, concerns about EDCs and ECCs are steadily increasing. This accumulation of organic waste and plastics in the environment generates significant environmental and health problems and increases the difficulty of disposing of them.

Know More

 

EDCs and ECCs occur widely in the environment, with several detected in the tissues of different aquatic species. However, the resultant environmental and health risks remain poorly understood, as evidenced by the lack of novel technologies for effectively detecting and removing them. Due to public health costs and the risks these pollutants pose there is an urgent need for a comprehensive environmental and health assessment of their presence in the Hong Kong environment. Organic waste products, including food waste and sludge, have been adopted successfully as raw materials to produce value-added materials, such as fish feed and eco-construction materials. This eases the waste disposal pressure on existing landfills and while simultaneously promoting a circular economy. Using inexpensive organic wastes to produce biodegradable plastics is another promising alternative for sustainable waste management, bringing various environmental benefits, such as true biodegradability.

 

ww

 

The project focuses on generating up-to-date information, including (1) quantification of EDCs and ECCs in the local water environment and urine samples, assessment of the concomitant environmental and health risks, and evaluation of the levels of these emerging pollutants in school students; (2) development of novel technologies for effectively removing EDCs and ECCs from wastewater and drinking water; and (3) conversion of organic waste into high-quality animal feed, biodegradable plastics, biochar, bio-adsorbents, biofuel, construction materials, and fertilizer. The potential usage of waste-derived resources to replace conventional materials for real applications can be further evaluated. Its findings have been transferred and transformed into inquiry-based teaching and learning materials and STEAM education activities for community education. 

ww

The research outcomes provide a sustainable, low-cost, and effective solution to the emerging environmental health and organic waste issues of great public concern, government needs and industry interests in Hong Kong and Asia. The most original aspect is the suggestion of using more-or-less conventional sewage and drinking water treatment plants to deal with the plethora of EDCs and ECCs, instead of implementing more costly tertiary treatment alternatives to target these emerging contaminants. In the long run, full-scale application of the proposed technologies can be expected to enable rapid adaptation of (1) the existing infrastructure for effective control and management of these emerging contaminants in the water environment, and (2) these materials for different environmental applications, such as safe food production, pollution control and management, soil nutrient management, and renewable energy recovery, both locally and globally.
