Performance of PE pipes under extractive conditions: Effect of the additive package and processing [PDF]

, 2014
Polyethylene (PE) compounds were prepared with five primary antioxidants and five application stabilizers, pelletized and extruded to pipes under industrial conditions. The pipes were stored in water at 80 °C for one year.

Biodegradation Behavior of Neat PLA Fibers Under Controlled Industrial Composting Conditions: Fiber Characterization and Physical Changes During the Composting Process

Journal of Applied Polymer Science, EarlyView.
Poly(lactic) acid (PLA) biodegradability in fiber form is relatively unexplored. This study shows that the drawing of the fibers during production affects the mechanical properties but slows down the biodegradation of the PLA. Biodegraded undrawn fibers showed peeling whereas drawn fibers showed crack formation on the surface.

Strain rate effect on the mechanical behaviour of a textile reinforced cement composite [PDF]

, 2010
The static tensile behaviour of Textile Reinforced Cement Composites is known and can be modeled adequately. However, using these static material properties under dynamic loadings such as impact and seismic loadings, can cause over- or underestimation of

Increasing the succinate yield in Actinobacillus succinogenes by fumigation of H2 in a bioreactor

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The microbial conversion of CO2 into value‐added chemicals offers a promising and scalable route for sustainable bioproduction, particularly under mild reaction conditions and with technically straightforward reactor configurations. Actinobacillus succinogenes, a natural succinate producer, can fix CO2 through anaplerotic carboxylation but its

Carbon‐based materials from renewable sources: Challenges and perspectives with a focus on green coconut

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract This article presents a comprehensive examination of agricultural production, biomass generation, and its transformation into biochar, with a particular emphasis on green coconut waste as a primary resource. It underscores the link between agriculture and substantial biomass output, shedding light on the ecological issues associated with solid

Film Blowing of Biobased Biodegradable Polyesters: Poly (Pentylene Adipate‐co‐Terephthalate) and Poly (Dodecylene Furanoate)

Macromolecular Materials and Engineering, EarlyView.
Two novel biobased and biodegradable polyesters are explored as replacements for commercial PBAT and LLDPE in flexible film applications. Although some differences exist between these new materials and the commercial materials, nothing appears to disqualify these new materials as being acceptable as drop‐in replacements for flexible film applications ...

A biodegradable polylactic acid–polybutylene adipate terephthalate–starch polymer blend for geotextile applications

Polymer International, EarlyView.
Biodegradable polymer blends are environmentally friendly materials with the ability to tailor material properties according to requirements. Abstract Geotextiles are typically used to stabilize steep earthen structures to prevent landslides. Usually, such geotextiles are made from petrol‐based polymers (such as polypropylene), but the use of ...

One‐Pot Upcycling of Heterogeneous Polyester Waste to Biodegradable Thermoplastics: A Cost‐Effective Solution for a Circular Economy

SusMat, EarlyView.
One‐pot melt transesterification upcycles post‐consumer PET and PBT with PTMG into biodegradable TPEEs featuring randomized polyester chains, tunable mechanical properties, and accelerated biodegradation. TEA and LCA analyses show competitive cost and reduced carbon emissions relative to PP and PBAT.
