The need for improved and safely managed sanitation facilities is acute in dense informal settlements in rapidly urbanizing areas. One of the key factors influencing the cost-effectiveness and reliability of service provision in informal settlements is the ability to optimize waste collection from latrines with variable use patterns that are spatially dispersed within an informal settlement. This study investigates how latrine sensors could be used to estimate waste fill levels and improve servicing efficiency for forty latrines in Nairobi, Kenya, supporting SDGs 3, 6 and 9.

Solar energy is an attractive clean energy source but storage and transportation is often a problem. Solar-light-driven water splitting provides a promising way to store and utilise abundant solar energy in the form of gaseous hydrogen. High temperature-promoted photocatalytic water splitting systems, described in this article, could open up a new direction for innovation in this field, furthering SDG 7 and 9.
World Smart Energy Week is the world’s leading comprehensive B-to-B trade show for smart and renewable energy held twice a year in Japan. (March in Tokyo and September in Osaka) The show aims to provide a platform for professionals from across Japan, Asia, and the world to negotiate and network for the future of smart and renewable energy business. This supports SDG 9: to build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation.

Cerium (IV) oxide, commonly known as ceria, is a rare-earth compound used in the optics industry to polish glass surfaces found in many high-tech products and components. Sending the spent polishing slurry, which contains high levels of total suspended solids, into the sewage system may damage natural ecosystems. This paper describes the work performed to evaluate technologies, design, and implement a system to recover more ceria and reduce TSS discharge from the ceria washwater operation. This supports SDG 9 and 12.

Renewable and Sustainable Energy Reviews, Volume 116, December 2019, 109388

Nepal has been suffering from a serious energy crisis for decades. It has severely affected its economic, social and political development. This paper furthers SDGs 7, 9 and 12 by showing that renewable resources are crucial not only for mitigating the present energy crisis, but also to ultimately provide energy independence for Nepal by establishing reliable and secure sources of energy.
This study advances SDGs 7, 9 and 12 by evaluating the environmental sustainability of biomass utilisation for small-scale power generation in rural communities, with a focus on the Southeast Asian context. Rice and coconut residues are considered for direct combustion and gasification, and livestock manure for anaerobic digestion. The results of this study are expected to support the development of sustainable bioenergy in off-grid rural communities as well as those that aim for greater energy independence.
This book chapter addresses goals 7, 9, and 13 by reviewing the prospects and constraints for bioenergy development in Africa to ensure sustainable bioenergy production in the future.
This book chapter addresses goals 9 and 12 by describing recycling methods including primary, mechanical, chemical and quaternary, to create new valuable products from plastic wastes and keep them out of landfill.
This case study shows the contribution of the Global Partnership for Sustainable Development Data to the Open Algorithms Initiative. It addresses how to unlock the potential of private sector data for public good purposed in a safe ethical, scalable and sustainable manner furthering goals 9 and 17.
This journal article addresses goals 9, 14, and 15 by assessing country-level overlaps between planned infrastructure expansion, infrastructure-threatened biodiversity, and national biodiversity compensation policies.
