Abstract Carbon fibres are widely used in carbon fibre reinforced plastics (CFRP) for aviation, automotive, windmills, sport and many more application due to their outstanding material properties. Annually, this generates about 62,000 tonnes of end-of-life (EoL) CFRP production waste. Current EoL scenarios CFRPs show some disadvantages: Landfilling incineration not sustainable environmentally f...

Handling plastic waste through recycling allows extending the life of polymeric materials, avoiding recurrence to incineration or landfilling. In contrast with traditional mechanical technologies, chemical enables obtention virgin monomers by means depolymerisation create new polymers same and thermal properties as originals. Research presented in this paper is part polynSPIRE project (Horizon ...

This paper reviewed the entire life cycle of plastics and options for management plastic waste to address barriers industrial chemical recycling further provide perceptions on possible opportunities with such materials.

The exact solutions for the isotopic compositions and the concentrations of the two-reservoir model for mantle-crust evolution are given for arbitrary rates of crustal growth and of back flow to the mantle. The critical parameters are the chemical fractionation factors for crustal growth and refluxing and the integrated fractional mass-removal rates from the crust and the mantle. For the case w...

The development of coimmobilized multi-enzymatic systems is increasingly driven by economic and environmental constraints that provide an impetus to develop alternatives to conventional multistep synthetic methods. As in nature, enzyme-based systems work cooperatively to direct the formation of desired products within the defined compartmentalization of a cell. In an attempt to mimic biology, c...

Disposing of plastic wastes to landfill is becoming undesirable due to legislation pressures, rising costs and the poor biodegradability of commonly used polymers. In addition, incineration meets with strong societal opposition. Therefore, recycling either mechanical or chemical, seems to be the only route of plastic wastes management towards sustainability. Polyolefins, mainly polyethylene (LD...

The chemical synapse is a specialized intercellular junction that operates nearly autonomously to allow rapid, specific, and local communication between neurons. Focusing our attention on the presynaptic terminal, we review the current understanding of how synaptic morphology is maintained and then the mechanisms in synaptic vesicle exocytosis and recycling.

The introduction of ecological sanitation (ECOSAN) toilets in villages near Bangalore hascreated opportunities for safer sanitation and recycling of human excreta, as fertilizers, in ruraland peri-urban areas. Field experiments were conducted at the University farm on French beansand Maize as the test crops in succession for 2 consecutive years in the same field. Differenttreatment combinations...
