Covestro has produced bio-based PU dispersions for textile applications
Growing demands from brand owners and consumers for fibres and textiles that are more environmentally friendly are now creating a huge market for bio-based polymers produced using renewable feedstocks. The textile and packaging industries have a significant impact on the environment: this report highlights how recent developments in new materials support SDG 9 Industry, Innovation and Infrastructure, and SDG 7 Affordable and Clean Energy.
This book chapter advances SDGs 14 and 3 by discussing the history of aquatic contamination, highlighting major cases where aquatic contamination has become an issue and cases where efficient solutions to environmental problems have been reached.

Energy geotechnics involves the use of geotechnical principles to understand and engineer the coupled thermo-hydro-chemo-mechanical processes encountered in collecting, exchanging, storing, and protecting energy resources in the subsurface. In addition to research on these fundamental coupled processes and characterization of relevant material properties, applied research is being performed to develop analytical tools for the design and analysis of different geo-energy applications. This paper summarizes some of the major research and practical developments in the emerging area of energy geotechnics which relates to SDG 7, 11 and 13.

Studies of waste-to-energy systems have applied a varying range of indicators to assess their sustainability. Through a literature review, this research aims to develop a framework of sustainability indicators that can serve as a reference for future research in waste-to-energy systems. Utilising this framework could helpd to advance SDG 7.2 to increase the share of renewable energy in the global energy mix.
This article highlights the winning proposals of the first edition of the Elsevier Foundation Green & Sustainable Chemistry Challenge. The winning proposals were chosen for their innovative green chemistry aspects and their large positive impact on the environment, contributing to SDGs 6, 12 and 15.
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.
