Chemicals and waste

The internal combustion engine does not efficiently convert chemical energy into mechanical energy and most of the energy is lost as heat. This paper discusses promising technologies for passive waste heat recovery system, addressing SDGs 9,12 and 13.
Recent research on CO2 capture is focusing on the optimization of CO2 absorption using amines (mainly monoethanolamine—MEA) in order to minimize the energy consumption of this very energy-intensive process and improve the absorption efficiency. This paper provides an overview of the main implications of using MEA for CO2 capture together with the latest advances in research to improve the conventional absorption process. The use of other solvents and/or technology, as well as their advantages and disadvantages will also be briefly provided. This is relevant for SDGs 9,12 and 13.

The aim of the study was to revise the current literature concerning the application of low-cost adsorbents for wastewater treatment highlighting, systematically, both adsorbents characteristics and adsorption capacities. This is particularly relevant to address SDG 6 - Clean water and sanitation.
Provision of clean water is one of the most important global issues. However, clean water resources are decreasing every day because of contamination by various pollutants including organic chemicals. This article discusses techniques to remove pollutants from clean water resources and thus contributes to the advancement of 6.3, which target the reduction of pollution, eliminating dumping and minimizing release of hazardous chemicals and materials which substantially increases water recycling.
A third of the 2.5 billion people worldwide without access to improved sanitation live in India, as do two-thirds of the 1 billion practising open defecation and a quarter of the 1.5 million who die annually from diarrhoeal diseases. This study looked at the effectiveness of a rural sanitation intervention in India, providing insight into how to reach SDG 6.2 to achieve access to adequate and equitable sanitation and hygiene for all and ending open defecation whilst paying special attention to the needs of women and girls and those in vulnerable situations.
Biomass-derived liquid transportation fuels and energy products have been proposed as part of the solution to climate change and thus support SDG 7 and 13 to increase renewable energy in the global energy mix and increase resilience against climate change. This article describes the key challenges and opportunities in modeling and optimization of biomass-to-bioenergy supply chains. Conclusions include potential future research on multi-scale modelling and optimization of biofuel value chains.
Focused on a Green Future
Italy's leading petrochemical producer, Versalis has taken a fundamental shift in its strategy and direction, to renew its focus on innovation and green chemistry, providing opportunities for growth. This is the ICIS/Versalis supplement about green and bio-based chemicals and sustainabliity with videos embedded. Green chemistry fits in with SDG 9 Industry Innovation and SDG 7 Affordable Clean Energy.

Currently lithium-ion (Li-ion) batteries used in significant numbers in vehicles are designed to last the life of the vehicle. They will not reach their end-of-life for another 10 years. This paper examines how the model used to recycle lead-acid batteries could be applied to Li-ion batteries and ensure steps are put in place so that the economical and sustainable benefits can be achieved at the end of its useful life. This addresses SDG 12, in particular waste reduction and reuse.
