Increasing global economic competitiveness, social inequalities and the dimension of environmental problems have raised awareness of the need to change the technological paradigm and challenge the technological status quo. Environmental innovations are essential in reducing environmental impacts and resolving the environment vs. economy dilemma, and chemistry has a significant role underpinning these innovations. Environmental innovations can be achieved via a combination of inputs, such as raw materials, energy and labour. These innovations may be specifically developed to targeted environmental damage, for instance, in response to regulations; or their benefit is the result of the environmental components of other types of innovations. In this symposium, we explore the role of innovative chemistry in: a) end-of-pipe solutions in which a technology is applied to a preexisting production system; b) technologies for pollution and wastes reduction and control; and c) approaches to tackle global environmental challenges. Innovative industrial solutions – this session presents the chemistry behind cutting-edge process-integrated changes in production technology that reduce the quantities of pollutants and waste generated during production. For instance, pre-composite polymers to create higher performing and greener architectural house paints; efficient and precision conversions of renewable raw materials into innovative polymeric products; process chemical that that optimize costs and increase machine efficiency, functional chemicals that lend specific properties and coating chemicals that improve the appearance and performance of finished paper and board. Life cycle analysis (LCA) is an important tool for environmental policy and for industry taking into account environmental impacts of the production process, and associated wastes and emissions, but also the future (downstream) fate of a product. Understanding the close interplay between LCA and chemistry will contribute to the forecasting of future material and energy fluxes on regional and global scales, provide a ‘green’ solution as a function of various economic growth and regulatory scenarios. Pollution and waste reduction – this session showcases the chemical technologies that minimize the release or presence of substances harmful to the environment as well as reduce waste by reutilization of materials recovered. Nano- and microparticles-based remediation methods represent a significant advance in the in situ decontamination of soil and groundwater pollution. Green jet fuel, from a new feedstock which can reduce the greenhouse gas emissions by 65 to 85% when compared to petroleum based fuels, is critically important. Low-energy process that uses chemical ligands to selectively recover noble metals can be recovered from secondary sources such as automotive scrap and waste electrical and electronic equipment (WEEE). Microbial fuel cells hold great potential in utilizing electrochemical and biological process to treat wastewater and also generate electricity from organic matter present in wastewater. Tackling global environmental challenges – Innovative chemistry can have a global reach to help tackling environmental issues in emerging economic countries. For example, an innovative but low-cost chemical process has been applied to improve the access to safe drinking water and sanitation worldwide. Bioinspired materials and devices that are fabricated artificially have been used to capture atmospheric water. Nanofertilisers and nanopesticides can be integrated into the science of formulation to facilitate more sophisticated products that may help to reduce the impact that modern agriculture has on environment and human health, and contribute to global food security. Using biomimetic strategy bioinspired materials have been designed and fabricated of for efficient atmospheric water collection to provide potential solution to global water crisis.
