From waste to wealth using green chemistry: The way to long term stability
This paper provides an overview on societal challenges and opportunities associated with waste valorization strategies, contributing to SDG 12. Moving away from the linear economy model, waste becomes a resource rather than a burden for the society. Focusing on two specific waste streams – namely plastics and food supply chain wastes – it explores a circular economy model. Bearing in mind that waste is a resource, initiatives all over the world should not only target minimizing or totally stopping land-filling but also reducing existing land-fills through landfill mining. In accordance with SDG 17, Clark suggests a three-way partnership between industry, government and the public – where each actor plays a specific role in promoting new technologies, developing supportive regulations and embracing a new consumption attitude towards waste.

An investigation of how the development of materials which can be formed, degraded and reformed into new materials can contribute to fulfill the expectations of eco-minded tourists who prefer hotels engaged in activities for protecting natural resources and working against waste accumulation, related to SDGs 9 and 12.

This article describes that by removing the organic solvents from the synthesis it is possible to reduce in about two orders of magnitude the emissions of CO2 in the production of the MOF material and also a reduction of one order of magnitude in the freshwater toxicity and resource depletion. The authors believe that this type of study can serve as an initial screen tool to assess the environmental performance of novel materials. Moreover, it can be used for establishing the necessity of recycling a given solvent or to find an alternative solvent that significantly reduces the environmental impact of novel materials.
The authors investigated the versatile use of droplet coagulation to recycle complex waste resources (fly ash FA, rice husk ash RHA and alum sludge AS). Monodisperse microspheres were shaped, creating higher impact on the applicability of the waste resources. Once a fluid suspension was obtained of the different powders, shaping could be performed without any impact of the powder characteristics. The aim of this research is to study the generic use of droplet coagulation on waste resources with variety in origin, composition and morphology and contribute to knowledge on sustainable materials, advancing SDG 11.

Production wells in oil and gas industries are continually exposed to highly corrosive environments during stimulation treatments such as acidization. Acid treatment is used to increase rock permeability. However, these acids can be corrosive and the corrosive inhibitors that are added are environmentally damaging. This paper explores the research into corrosion inhibitors that are environmentally friendly, contributing to SDG 13.

Traditional nutrient recycling systems in China have been recognized as a good model for long-term sustainability. Nevertheless, the traditional philosophy has not been well inherited in modern society, and the consequences of environmental degradation from the changed nutrient management systems have not been well recognized by the public. If the additional nutrient sources in future urbanization cannot be well recycled, people will face more challenging environmental problems. The analysis of the environmental and economic costs from wastewater treatment systems indicates that the road for nutrient management after the 1980s was not the right choice. China should re-evaluate the value of the traditional philosophy and develop new technologies to meet modern socioeconomic requirements. These insights support many of the targets to advance SDG 11 Sustainable cities and communities.

Over the last decades, considerable attention has been directed towards the use of water as a medium in organic synthesis for sustainability, non-toxicity and safety reasons. In support of SDG 12, the paper presents the most recent advances in applications of alternative medium to replace polar aprotic solvents such as dimethylformamide (DMF), dimethylacetamide (DMAc) or N-methyl-2-pyrrolidone (NMP). Focus is made on the use of nonionic designer surfactant (e.g. TPGS-750-M) in water instead of traditional organic solvents.
This Practice Note from LexisPSL explains when environmental impact assessments (EIA) are required in the UK; the EIA procedure; the relationship between EIA and planning applications; the Rochdale Envelope; challenging an EIA decision and the court’s discretion to quash; EIA for nationally significant infrastructure projects; and upcoming amendments to the EIA process. EIAs advance SDG 11.3 to enhance inclusive and sustainable urbanization and capacity for participatory, integrated and sustainable human settlement planning and management in all countries.
This Practice Note from LexisPSL considers a number of interesting developments in EU environmental law and policy as it relates to energy efficiency, waste, environmental reporting and chemicals. It also serves to highlight a number of deadlines for relevant implementation and reforms as they relate to companies. These measures will help to advance SDG 7 Energy, SDG 11 Sustainable cities and communities and SDG 12 Sustainable consumption and production.

Finishing 3,000 dairy-bred beef cattle on waste food while producing green energy and fertiliser as by-products is the sustainable model for one Cambridgeshire farmer and his business partner. This approach helps meet the criteria for SDG 7 of access for all to affordable, reliable, sustainable and modern energy and SDG 12 which promotes responsible consumption and production.
