The benefits of biodegradable and compostable (B&C) products are attained when the organic waste (OW) is composted. B&C products may improve the management of OW, so that greater and cleaner OW flows can be collected and composted. In this paper we show the case of the catering sector as an example of this. Disposable tableware is usually distributed at fast food restaurants and town festivals....

At present, the commercial production of hydrogen is essentially carried out by catalytic steam reforming of hydrocarbons: natural gas and naphtha. However, the instability of the prices of natural gas makes the use of other raw materials increasingly attractive. This research focuses on the development of a technology for producing hydrogen from alternative resources, specifically from two typ...

this paper discusses about preparation of biodegradable polymer /clay nanocomposites based on organically modified montmorillonite clay; i.e. cloisite 10a and biodegradable polymer chitosan by solution mixing technique and their characterization. the nanocomposites were successfully prepared and their structures were characterized by powder x-ray diffraction (xrd), particle size analyzer (beckm...

As a clean and renewable source of energy, ethanol is a promising alternative to fossil fuels.1 Especially lignocelluloses, as raw material for ethanol production, have gained great interest during these years.2 Production of bio-ethanol will help to cope with the over-consumption of fossil fuels and further work for the reduction of carbon dioxide emissions. Lignocelluloses (crop residue, cell...

Many attempts to create bio-plastics from renewable resources have been made in recent years. The main aim of these studies has been to develop products competitive with synthetic polymers. Two main strategies have been studied to produce reasonable yields of these polymers: transgenic plant cells1 and the well known bacterial fermentation process.2 Among the various candidates for biodegradabl...

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...

Plastics pollution is causing an environmental crisis, prompting the development of new approaches for recycling, and upcycling. Here, we review challenges opportunities in chemical biological catalysis plastics deconstruction, We stress need rigorous characterization use widely available substrates, such that catalyst performance can be compared across studies. Where appropriate, draw parallel...

The promotion of sustainable packaging is part the European Green Deal and plays a key role in EU’s social political strategy. One option use renewable resources biomass waste as raw materials for polymer production. Lignocellulose from annual perennial industrial crops agricultural residues are major source polysaccharides, proteins, lignin can also be used to obtain plant-based extracts essen...
