Polyurethane foams are materials characterized by low density and thermal conductivity and
can therefore be used as thermal insulation materials. They are synthesized from toxic and …

Cellulosic fiber (CF) in nanoform is emergingly finding its way for COVID-19 solution for
instance via nanocomposite/nanoparticle from various abundant biopolymeric waste …

In this study, the possibility of using sawdust, a by-product of primary wood processing, as a
filler (WF) for rigid polyurethane (PUR) foams was investigated. The effects of the addition of …

Tropical fibre bundles of Rhecktophyllum camerunense (RC) and Ananas comosus (AC)
extracted from the equatorial region of Cameroon were characterised and used as fibrous …

The use of lignocellulosic fibers as fillers in polymer matrices has aroused the interest of the
scientific community and industrial sectors. In Brazil, the high macadamia consumption has …

The search for environmental sustainability has stimulated the construction sector to look for
natural materials with an ecological footprint, high strength/weight ratio, and better thermal …

This paper presents results of research on the preparation of biochar-modified rigid
polyurethane foams that could be successfully used as thermal insulation materials. The …

Currently, the recycling potential of wood waste (WW) is still limited, and in a resource
efficiency approach, recycling WW in insulation materials, such as polyurethane (PUR) …

Oil spills cause serious ecological threats to aquatic life. High-performance polymer
composite films using biomass fibers for rapidly removing oil from wastewater are …

In the paper, the authors presented a polyurethane material with the addition of
microspheres derived from coal fly ash. The filler addition ranged from 5 to 20%. The …
