Chemicals and waste

EcoWASTE Exhibition is the leading international platform in the Middle East and North Africa (MENA) region for advancing sustainable waste management and recycling. EcoWASTE Exhibition brings together leading local and international experts and providers with key buyers and decision-makers. This directly supports SDG 12, including target 12.4: By 2020, achieve the environmentally sound management of chemicals and all wastes throughout their life cycle, in accordance with agreed international frameworks, and significantly reduce their release to air, water and soil in order to minimize their adverse impacts on human health and the environment
Huge amounts of food waste exist in the consumption stage in developed countries. The waste can be converted into safe, nutritious, and value-added livestock feeds. ReFeed can be a game changer, simultaneously addressing multiple challenges such as food security, resource and environmental sustainability, and climate change. This is related to SDG's 2, 12, 13 and 14.
This article outlines a new chemical design strategy focused on Eastman Chemical’s development of a novel, green chemistry based solvent called Omnia. Innovating with intent aptly describes the interdisciplinary process Eastman took in developing and commercializing Omnia, from the early engagement of chemists and toxicologists to identify safe molecules, to the pilot testing for performance with a small scale formulator, to making the economic, performance, and sustainability case internally and externally. Perkins also notes some of the challenges of developing and commercializing a novel solvent and the critical need for early supply chain engagement given the high cost, time, and risk associated with bringing safer ingredients to market exploring issues related to SDGs 9 and 12.
Venus and Alexandri present a model to bridge the organic waste sector and the chemical production sector to develop bio-based platform chemicals, showing connectedness of SDGs 9,11 and 12. Starting with an overview of some of the potential feedstock routes to bio-based platform chemicals, the authors provide an overview of the opportunities, value, production routes, and examples of companies producing these platform chemistries. They conclude with a number of technical and institutional challenges to bio-based platform chemical production as well as potential opportunities moving forward.

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.
