Chemical engineering for the Anthropocene Open
The environmental and resource crises that confront human life on earth demand changes to the whole socio‐economic metabolic system. The changes will affect all aspects of life, including the practice of chemical engineering. The historica…

Chemical engineering and industrial ecology: Remanufacturing and recycling as process systems Open
Climate change and resource scarcity are just two of the planetary crises that make radical socio‐economic change essential if human society is to be sustainable. Chemical engineering is a skill‐set that can make a unique contribution to t…

A Circular Economy Approach to Military Munitions: Valorization of Energetic Material from Ammunition Disposal through Incorporation in Civil Explosives Open
Ammunition that has reached its end of life or become obsolete is considered hazardous waste due to the energetic material content that must be decommissioned. One of the technologies to dispose of ammunition involves the use of incinerato…

Managing Plastics: Uses, Losses and Disposal Open
The term ‘plastic’ refers to a wide range of different materials with diverse properties and uses. Plastics are essential in a modern industrial economy. Plastic pollution results from the ‘leakage’ of plastics into the unconfined environm…

Radiological impact assessment approaches for Life Cycle Assessment: a review and possible ways forward Open
Many industrial processes routinely release radionuclides into the environment. Such emissions may be recognised in the inventory phase of Life Cycle Assessment (LCA), but they are rarely carried forward to the Life Cycle Impact Assessment…

Can the SDGs Provide a Basis for Supply Chain Decisions in the Construction Sector? Open
The Construction sector is characterised by complex supply networks delivering unique end products over short time scales. Sustainability has increased in importance but continues to be difficult to implement in this sector; thus, new appr…

A life cycle assessment data analysis toolkit for the design of novel processes – A case study for a thermal cracking process for mixed plastic waste Open
The earlier in the development of a process a design change is made, the lower the cost and the higher the impact on the final performance. This applies equally to environmental and technical performance, but in practice the environmental …

An on demand chilling system: Activated carbon based desorptive cooling Open
Every year in Europe refrigerant gases with a greenhouse-warming equivalent of more than 30 Mt CO2 are emitted from retail refrigerators. Furthermore, the effective efficiency of such refrigerators is far below that achievable under ideal …

Liquefied natural gas for the UK: a life cycle assessment Open
Liquefied natural gas (LNG) is expected to become an important component of the UK's energy supply because the national hydrocarbon reserves on the continental shelf have started diminishing. However, use of any carbon-based fuel runs coun…

The Challenges of Applying Planetary Boundaries as a Basis for Strategic Decision-Making in Companies with Global Supply Chains Open
The Planetary Boundaries (PB) framework represents a significant advance in specifying the ecological constraints on human development. However, to enable decision-makers in business and public policy to respect these constraints in strate…

Life cycle engineering of production, use and recovery of self-chilling beverage cans Open
The chill-on-demand system is a new technology designed to provide cooled products on demand, thereby avoiding chilled storage. It uses the cooling effect provided by endothermic desorption of carbon dioxide previously adsorbed onto a bed …

Shale gas: a life-cycle perspective for UK production Open
Following the boom of shale gas production in the USA and the decrease in the US gas prices, increasing interest in shale gas is developing in many countries holding shale reserves and exploration is already taking place in some EU countri…

Urban Cultivation and Its Contributions to Sustainability: Nibbles of Food but Oodles of Social Capital Open
The contemporary interest in urban cultivation in the global North as a component of sustainable food production warrants assessment of both its quantitative and qualitative roles. This exploratory study weighs the nutritional, ecological,…

Life Cycle Assessment of activated carbon production from coconut shells Open
Activated carbons have excellent performance in a number of process applications. In particular, they appear to have the most favourable characteristics for adsorption processes, thanks to their high porosity and large surface area. Howeve…

Stocks and Flows in the Performance Economy Open
The performance economy is a concept which goes beyond most interpretations of a "circular economy": the focus is on the maintenance and exploitation of stock (mainly manufactured capital) rather than linear or circular flows of materials …
