Waste Energy Recovery in Internal Combustion Engines
Waste Heat Recovery (WHR) is a very interesting opportunity since almost two-thirds of fuel energy is not converted into mechanically useful energy. Moreover, the integration with other thermal streams on board (cooling and lubricating mediums, EGR cooling) can add further value to the recovery opportunity as well as the concept of managing the engine thermal management which can produce a sensible contribution that is appreciated mainly during urban driving. A huge scientific effort is underway, and a great expectation is perceptible. More generally, the technological options that can achieve a reduction in overall fuel consumption and, thus, the improvement of global engine efficiency, are the most valuable when they can be introduced without massive changes to the engine layout. This happens in all the energy applications in which Internal Combustion Engines (ICEs) are involved since the recovery unit can be introduced in the exhaust line. The mechanical energy recovered can be easily transformed into electrical energy, so represents an interesting integration with the hybrid propulsion powertrains.

Waste Cooking Oil for Biofuel in India
Waste or used cooking oil (WCO/UCO) is a common source of trans fat consumed by Indians, leading to many non-communicable diseases like diabetes, hypertension, cardiovascular diseases, stroke, cancer, etc. In fact, out of 230 million MT of edible oil consumption, India is currently capable of producing only 3 million MT of biodiesel. Moreover, with the increased emphasis on the circular economy to improve rural employment opportunities, India should adopt a complete exergy analysis of biodiesel production from WCO.

Waste Cooking Oil for Asphalt Modification
Waste cooking oil (WCO) is considered a potential bio-based waste material because it can lead to multiple topologies of the product. WCO is generated after frying activities, and the rising population has increased its quantity due to the increased demand for food. WCO is related to the vegetable oil family and mainly arises from the kitchen and food industry.

Waste Cooking Oil Biodiesel
To reduce the emissions caused by running the compression ignition engines, waste cooking oil (WCO) biodiesel is one of the best alternative fuels locally available in all parts of the world. WCO biodiesel cuts down the emissions value by 85% due to decreased hydrocarbon, SO2, CO, and smoke emissions in the exhaust that will effectively save the environment.

Waste Biorefineries
Sustainable biofuel production is the most effective way to mitigate greenhouse gas emissions associated with fossil fuels while preserving food security and land use. In addition to producing bioenergy, waste biorefineries can be incorporated into the waste management system to solve the future challenges of waste disposal. Biomass waste, on the other hand, is regarded as a low-quality biorefinery feedstock with a wide range of compositions and seasonal variability. In light of these factors, biomass waste presents limitations on the conversion technologies available for value addition, and therefore more research is needed to enhance the profitability of waste biorefineries. Perhaps, to keep waste biorefineries economically and environmentally sustainable, bioprocesses need to be integrated to process a wide range of biomass resources and yield a diverse range of bioenergy products.

Waste as Cement Replacement in Foamed Concrete
Foamed concrete is a lightweight construction material that has gained popularity due to its excellent thermal and acoustic insulation properties. Foamed concrete production involves using cement as a binding agent, which results in a high carbon footprint. In response to sustainable development goals (SDG), there has been a growing interest in exploring alternative materials that can replace cement to improve energy efficiency, climate change, resource efficiency, and overall improvement of foamed concrete properties.

Waste and Waste-to-Energy Technologies
A World Bank report estimated that 2.01 billion tonnes of municipal solid waste (MSW) is generated worldwide annually, and this is expected to increase to about 3.4 billion tonnes by the year 2050. Waste incineration with energy recovery is a waste-to-energy (WtE) technology which has been established to be an appropriate method of dealing with MSW worldwide.

Washing Damage in E-Textiles
E-textiles, hybrid products that incorporate electronic functionality into textiles, often need to withstand washing procedures to ensure textile typical usability. Yet, the washability—which is essential for many e-textile applications like medical or sports due to hygiene requirements—is often still insufficient. The influence factors for washing damage in textile integrated electronics as well as common weak points are not extensively researched, which makes a targeted approach to improve washability in e-textiles difficult.
