Waste Management's Response to Climate Change in Singapore >>>

Hapag-Lloyd has announced that Effective February 16, 2026 a completed Letter of Indemnity (LOI) is mandatory for shipments of plastic scraps and metal scraps

The report warns of the staggering amount of mismanaged plastic waste generated and urges action to tackle this important problem.

New facility can extract precious metals from spent batteries for reuse in making new ones.

Report outlines major global efforts, investments and commitments to end plastic waste in the environment and contributing to a circular economy.

Our Crowd Sourcing Campaign is supported by the global WtERT network, represented by seventeen organizations from thirteen countries.

A novel biomass gasification-based combined cooling, heat and power (CCHP) system, which is composed of a gas-fueled internal combustion engine, variable-effect LiBr-H2O absorption cooling, and dehumidification air-conditioning with desiccant coated heat exchangers, was introduced. This work enables to contribute valuable data to the practical application of the biomass gasification-based CCHP system in Singapore's building sector.

This annual report summarizes WtERT-Germany's activities, like the outcome of the website's relaunch, our consultancy projects in Croatia and Tunisia as well as hosting/delegation of guests in 2018. In addition, it gives a glimpse of what we are about to do in 2019.

Dr. Gregorz Lisak from WtERT Singapore and Dr. Dorota Bankiewicz have had a tour from Rolf Waller at the waste incineration plant at the city of Rosenheim.

A life cycle assessment (LCA) was conducted to determine the best solution for dealing with the food waste (FW) generated in Singapore eateries. Since the representativeness of the life cycle inventory (LCI) data determined the overall quality of the LCA, this study made a significant endeavor to capture the local specificities, such as waste composition, water supply and treatment plant operation.

The world today committed to a pollution-free planet at the close of the UN Environment Assembly in Nairobi, with resolutions and pledges promising to improve the lives of billions across the globe by cleaning up our air, land and water.

Now Grzegorz Lisak (Head of WtERT-Singapore) has been appointed as a member of EAPES.

A novel compact three-stage anaerobic digester (HM3) was developed to combine the advantages of high solids anaerobic digestion (AD) and wet AD for co-digestion of food waste and horse manure. By having three separate chambers in the three-stage anaerobic digester, three different functional zones were created for high-solids hydrolysis, acidogenesis and wet methanogenesis. The results showed that the functionalized partitioning in HM3 significantly accelerated the solubilization of solid organic matters and the formation of volatile fatty acids, resulting in an increase of 11~23% in methane yield. VS reduction in the HM3 presents the highest rate of 71% compared to the controls. Pyrosequencing analysis indicated that different microbial communities in terms of hydrolyzing bacteria, acidogenic bacteria and methanogenic archaea were selectively enriched in the three separate chambers of the HM3. Moreover, the abundance of the methanogenic archaea was increased by 0.8~1.28 times compared to controls.

Current centralized sanitation systems adopted by many developed and developing countries minimize the exposure of wastewater to citizens by flushing them away from households. However, the transportation process consumes large amounts of energy and water and gives rise to diluted sewage. In contrast, decentralized sanitation systems that treat source separated wastewaters would encourage the recycling of nutrients for agriculture, reduce household water consumption significantly and generate a source of clean energy. This study is initiated by an attempt to redefine urban communities as renewable resource recovery centres through the adaptation of “decentralized and source-separationbased sanitation concepts.

Municipal Solid Waste includes commercial and residential wastes generated in municipal or notified areas, in either solid or semi-solid form excluding industrial hazardous wastes, but including treated bio-medical wastes (MoEF, 2000). The quality and quantity of MSW generated by a particular community will vary according to their socio-economic status, cultural habits, urban structure, population and commercial activities. Asian countries are facing MSWM problems due to the rapid growth in MSW generation rate. The total quantity of waste generated by 23 metro cities in India was 30,000 tpd in 1999, which has increased considerably to about 52,000 tpd (Inance et al, 2004).
