Chemicals and waste

This book chapter addresses goals 7, 13 and 11 by looking at ecological technologies that transform natural resources into anthropocentric goods and services.
Increased demand for food to feed the ever-growing population led to development and adoption of synthetic chemicals as a quick and effective strategy of managing crop pests and diseases. However, overreliance on synthetic pesticides is discouraged due to their detrimental effects on human health, the environment, and development of resistant pest and pathogen strains. This, coupled with increasing demand for organically produced foods, stimulated search for alternative approaches and botanical pesticides are particularly gaining importance.

Plastic Waste and Recycling, Environmental Impact, Societal Issues, Prevention, and Solutions, 2020, pages 223 - 249

This book chapter addresses goals 14, 15, and 12 by exploring the origins of microplastics (relating to our society, production and consumption) and the diverse and harmful impacts of microplastics in the marine environment on life underwater, as well as interactions with humans and other life on land at the end of the cycle.
Chioma Blaise Chikere, 2017 second prize winner of the Green Sustainable Chemistry Challenge
In 2017, Chioma Blaise Chikere was awarded the second prize of the Green and Sustainable Chemistry Challenge. Her project “Eco-restoration of crude oil-polluted land in Nigeria” demonstrated how organic nutrients such as garden fertilizers and animal excreta can be used to degrade hydrocarbons, cleaning up the soils heavily contaminated by decades of oil spills and advancing SDGs 6, 13 and 15. Three years later, we caught up with Dr. Chikere to learn about her research journey.
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.
Furthering SDG 7, this paper suggests a new way of preparing n-type Mg3Sb2-based Zintl compounds with high thermoelectric performance. It demonstrates that a large amount of extra Mg is not needed to achieve high ZT as long as Mg vacancies are suppressed and carrier concentration is properly optimized.

Veterinary Anaesthesia and Analgesia, Volume 46, Issue 4, July 2019, Pages 409-420.

This paper looks at a number of ways that veterinary anaesthetists can reduce their environmental impact, including by minimizing release of halogenated anaesthetics (which are potent greenhouse gases). This relates to SDGs 12 and 13.
The abundance of residual colors in the effluents discharged from textiles, tanneries, dyeing, food processing and numerous other industries across the globe, currently poses a grave threat to global environmental sustainability. Polymer enhanced ultrafiltration (PEUF) can be a cost effective and energy-efficient membrane separation process in the treatment of wastewater. This article supports SDGs 6, 12 and 14.

Encyclopedia of Renewable and Sustainable Materials: Nanomaterial for CO2 Sequestration, Volume 3, 2020

This book chapter advances SDGs 7, 13, and 12 by describing promising nanomaterials for the capture of CO2 emissions. Since it will take time for the world to rely solely on renewables, nanomaterials for carbon capture can help protect the atmosphere from harmful greenhouse gases in the interim.
Mercury contamination in soil, water and air is associated with potential toxicity to humans and ecosystems. Industrial activities such as coal combustion have led to increased mercury (Hg) concentrations in different environmental media. This review critically evaluates recent developments in technological approaches for the remediation of Hg contaminated soil, water and air, with a focus on emerging materials and innovative technologies. Extensive research on various nanomaterials, such as carbon nanotubes (CNTs), nanosheets and magnetic nanocomposites, for mercury removal are investigated.
