Energy

The use of biomass for energy production is one way to ensure energy security and address the environmental issues related to the use of fossil fuels in developing countries. Small and medium-sized enterprises (SMEs) need electric power and thermal energy for their activities. In Burkina Faso, this type of thermal energy is generally produced by SMEs from firewood. However, cashew companies produce a large amount of waste (shell, press cake, nut shell liquid) which can be converted into fuel. Separating the cashew nut from the shell requires two energy-intensive steps: roasting and drying.

Rural communities in developing countries often require small cold storage for vital medicines while having no access to electricity. The utilization of waste heat – produced in biomass burning cookstoves during daily cooking routines – to power a thermoacoustic engine driving a thermoacoustic refrigerator is investigated. The simplicity and affordability is met by the use of atmospheric air as working medium, cheap PVC ducting for acoustic waveguides and locally available blacksmithing technologies for simple heat exchangers.

An ability to separate battery electrode materials while preserving functional integrity is essential to close the loop of material use in lithium-ion batteries. However, a low-energy and low-cost separation system that selectively recovers electrode materials has not yet been established. In this study, froth flotation experiments were carried out with a variety of new and spent lithium-ion batteries using kerosene as the collector. The products were characterized using thermogravimetric and chemical analysis.

There is a need to develop technology to enable a resource-efficient and economically feasible recycling system for lithium-ion batteries and thus assure the future supply of the component materials. Lithium-ion batteries are complex products, and designs and materials are still evolving, which makes planning for future recovery more challenging. Several processes for recycling are proposed or operating, and each has advantages and disadvantages. This paper compares these processes on technical and economic bases, elucidating differences in benefits as a function of cathode composition.
Waste Li foils in the spent experimental Li-coin-cells may bring the potential risk and the waste of Li-resource if they aren't reasonably treated in time. For this purpose, waste Li foils were recycled in the form of black LiFePO4/C powders with the recovery of about 80% in this work.

The European Union implemented Ecodesign and Labelling Directives to support the market diffusion of energy efficient products. Accurate signals for consumers on energy efficiency (EE) are essential, as disinformation might lead to sub-optimal market allocations. Considering complex devices such as heat pumps (HPs), a conflict between simplicity of calculation on the one hand and accuracy on the other hand arises.
The increase in population coupled with rising per capita income and associated change in consumption habits will put unprecedented stress on food, energy and water (FEW) resources. Sustainable and reliable fresh water supply is central for life and also for all sectors that support our existence. Uncertainty on water security prompted interest in investigation of renewable energy driven desalination processes. One particularly promising option is to produce fresh water from the two most abundant resources on earth: solar energy and seawater.

Scottish farmers have been using clean energy technology normally used by buses and bin lorries to power their farm machines, helping to reduce emissions and make efficiencies. This helps to advance both goal 7 and goal 12.
All-Energy 2018
All-Energy, the UK’s largest renewable energy and low carbon event, is taking place on 2nd & 3rd of May 2018 in Glasgow; it brings together the UK’s largest group of buyers across the value chain, including investors, project developers, end users and policy makers, among others. Showcasing the complete range of renewable and sustainable technologies and with a world-class free-to-attend conference alongside, All-Energy brings together over 7,500 supply chain and business energy end users – including the largest group of renewable energy developers and supply chain partners seen anywhere in the UK.
