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 implement this sector; thus, new approaches and practices are needed. This paper reports an empirical investigation into the value of UN Sustainable Development Goals (SDGs), especially Consumption Production (SDG12), when used as a framework for action organisations drive change towards...
The transition towards a decarbonised electrical power system has consequences for the operation of Anaerobic Digestion (AD) providing an incentive to respond dynamic demand electricity. Therefore, models predict and control AD process are interest. A large number exist, however, none seems fit routine use in industry, being either too simple inaccurate, or complex. Consequently, aim this paper is develop new moderately complex model design operational intra-day on-demand electricity...
Globally, 2.8 billion people still cook with biomass, resulting in health, environmental, and social challenges; electric cooking is a key option for transition to modern energy services. However, assumed be too expensive, grids can unreliable the connection capacity of mini-grids solar home systems widely insufficient. Developments higher performance lower cost batteries photovoltaics help, but they raise questions affordability environmental impacts. The range issues wide, existing studies...
Abstract This paper presents five case studies on waste electrical and electronic equipment (WEEE) recycling to provide a coherent overview the likely impact of eco‐design measures plastics used in energy‐related products within EU. Whilst some measures, such as improving disassembly plastic parts, may generally benefit operations, other were found be ineffective or requiring further investigation. For example, product polymer marking, provision product‐specific information was rarely...
This paper provides recommendations for assessing the criticality of materials (metals and non-fuel minerals), including need context-dependent assessment methods, providing a framework conducting assessments. Materials captures concerns over accessibility materials, as product material’s ‘supply risk’ impact supply restriction. Through review selected studies, problems with assessments are discussed, highlighting how these become particularly important when results used in decision making....

Summary Mobile phones offer many potential social benefits throughout their lifetime, but this life is often much shorter than design intent. Reuse of the phone in a developing country allows these to be fully realized. Unfortunately, under current state development recycling infrastructure, recovery rates after reuse are very low those markets, which may lead an environmental burden attributed loss materials landfill. In order recover most effectively, developed countries best option, at...
Agriculture and forestry (including land use changes) contribute approximately 30% of anthropogenic greenhouse gas (GHG) emissions globally, but have a significant mitigation potential. Several activities to reduce GHGs at landscape scale are under development (e.g. Reducing Emissions from Deforestation forest Degradation or Clean Development Mechanism projects) these will not be effective without improvements the basic management scale: farm. A number farm-level GHG calculators been...
Editorial on the principle that “Chemical products should be designed so at end of their function they do not persist in environment and break down into innocuous degradation products”.
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 such refrigerators is far below that achievable under ideal (e.g. optimal-load; minimum access) operation. In this work design an alternative on-demand cooling unit presented. The based on effect provided by desorption carbon dioxide previously adsorbed onto bed graphite-bonded activated carbon: paper, case study...
