Mechanical and thermal properties of recycled polyethylene/surface treated hemp fiber bio‐composites

Polymer Composites, Volume 44, Issue 8, Page 4976-4992, August 2023., 2023
This study presents the production of economic, mechanically, and thermally stable polymer composites via their sustainable and reusable components with an environmentally friendly approach. Abstract Hemp is a good option for polyethylene additives because of its high cellulose and fibrous content. This study aims to modify natural hemp fibers with the

Cement composites reinforced by short curaua fibers [PDF]

Matéria (Rio de Janeiro), 2010
The development of an eco-friendly material that could reduce CO2 emission and that could aggregate value to a natural fiber, setting man at the countryside and raising the income of populations from poor regions is a challenge. Lignocellulosic fibers are cheap and are a readily available reinforcement, requiring only a low degree of industrialization ...

Recent trends in nanocomposite packaging films utilising waste generated biopolymers: Industrial symbiosis and its implication in sustainability

IET Nanobiotechnology, Volume 17, Issue 3, Page 127-153, May 2023., 2023
Utilisation of residual biomass could act as green and sustainable approach to lessen the waste burden on Earth and fulfiling the demand for bio‐based goods. Using waste as a raw material through industrial symbiosis should be taken into account as one of the strategies to achieve more economic and environmental value through inter‐firm collaboration ...

The influence of alkaline treatment on the mechanical performance of geopolymer composites reinforced with Brazilian malva and curaua fibers

Journal of the American Ceramic Society, Volume 106, Issue 1, Page 339-353, January 2023., 2023
Abstract Lignocellulosic fibers obtained from the curaua (Ananas erectifolius) and malva (Malva sylvestris) plants in Brazil can be used as suitable reinforcements for geopolymers (GPs) owing to their high strength, ready regional availability, and low cost.
