New thermal insulation fiberboards from cake generated during biorefinery of sunflower whole plant in a twin-screw extruder

Construction particleboards made from rapeseed straw glued with hybrid pMDI/PF resin

“…Yet, boards made from kenaf with even lower density of 200 kg/m 3 were characterized by λ varying from 0.04 to 0.065 W/mK (Xu et al 2004). The investigated rapeseed particleboards with a density from 500 to 600 kg/m 3 are comparable with boards with a density of 535-682 kg/m 3 made from sunflower husk: the value λ varied from 0.075 to 0.079 W/mK (Evon et al 2014;Cosereanu et al 2015). Obviously, boards with lower density are characterized by less coherent structure.…”

Comparison between two different pretreatment technologies of rice straw fibers prior to fiberboard manufacturing: Twin-screw extrusion and digestion plus defibration

“…Recently, Vandenbossche et al (2016Vandenbossche et al ( , 2015Vandenbossche et al ( , 2014 used the twin-screw extrusion technology for conducting the thermo-mechanical and thermo-chemo-mechanical pretreatment of different lignocellulosic biomass sources, in the case not for the subsequent manufacture of composite materials but for the production of second-generation bioethanol using a biocatalytic action. Evon et al (2015Evon et al ( , 2014Evon et al ( , 2012Evon et al ( , 2010aEvon et al ( , 2010b) also produced self-bonded fiberboards from the cake generated during the biorefinery of sunflower whole plant using a twin-screw extruder. In addition, Theng et al (2015a) prepared a thermo-mechanical pulp from corn biomass by digestion plus defibration to produce binder-free fiberboards.…”

Investigation of energy efficiency of innovate thermal insulating materials and their influence on the building heat regime

“…This material is applied to the isolated surface, as a paint, and after drying forms a polymer coating, which is characterized by considerable resistant to atmospheric One of the most upcoming trend of IM development -use of biomaterials and biotech waste. Modern researches prove the possibility of manufacturing of such materials: silkworm cocoon [5], rice straw [6], kenaf (Hibiscus cannabinus) [7] and sunflower (Helianthus annuus) [8].…”

“…The extensive usage of these materials can increase the processing depth of agricultural raw materials, providing nearly non-waste production [8].…”
