This study investigates the fire resistance capabilities of newly developed loose-fill thermal insulation materials crafted from annual plants such as wheat straw, corn stalk, and water reed. Three processing methodologies were employed: mechanical crushing (raw, size ≤ 20 mm), chemi-mechanical pulping (CMP) using 4% sodium hydroxide, steam explosion (SE). An admixture boric acid (8%) tetraborate (7%) was added to all treated enhance retardancy. The reaction characteristics assessed a cone...

The demand for eco-friendly packaging materials has urged researchers to look alternatives petroleum-based polymers. In this regard, paper-based products have turned out be a promising choice; however, their weak resistance water limited application. use of various additives enhance paper’s moisture is common practice. However, considering the growing global agenda sustainable development, search new bio-based paper become increasingly important. This study investigated potential synergistic...

Lignocellulosic biomass (LCB)-based thermal insulation materials available in the market are more expensive than conventional ones and consist mainly of wood or agricultural bast fibers which primarily used construction textile industries. Therefore, it is crucial to develop LCB-based from cheap raw materials. The study investigates new locally residues annual plants like wheat straw, reeds corn stalks. treatment was performed by mechanical crushing defibration steam explosion process....

The present study evaluates mold fungal resistance of newly developed loose-fill thermal insulation materials from wheat straw, corn stalk and water reed. Three different processing methods raw was performed by mechanical crushing (Raw, ≤ 20 mm), thermal-mechanical pulping (TMP) using 4% NaOH steam explosion (SEP). An admixture boric acid (8%) tetraborate (7%) applied to all processed substrates due their anti-fungal properties. Additionally, the fourth sample group prepared SEPs species...

Abstract The preparation of self-binding lignocellulosic fibreboards has been investigated. Different high-density (HDF) were hot-pressed based on a mixture grey alder ( Alnus incana L. Moench) wood chips processed by steam explosion auto-hydrolysis (SE) and 15% or 25% lignin content from three different industrial sources: softwood kraft (SWKL), soda wheat straw (SoWhStL) hydrolysis (HWhStL). Density, thickness swelling (TS) after immersion in water for 24 h, modulus rupture (MOR),...

Bio-aggregate composites (BACs) are typically formed by binding plant origin aggregates using organic or inorganic binders. Composite boards being manufactured from hemp shives and Portland cement lime such material is associated with the so-called “hempcrete”. To reach a low greenhouse gas emission rate, alternative binders must be considered. Gypsum binder releases seven times lower amount of CO2 during production compared cement, while waste gypsum can even more efficient. In this...

In the current decade, based on European Green Deal, new challenges of wood-based panel industry have arisen, seeking for formaldehyde-free bio-based adhesives and broadening raw lignocellulosics. order to contribute potential solution challenges, binder-less boards steam-exploded (SE 220 °C/2 min) hemp shives wheat straw were investigated. The objective this study was find out optimal hot-pressing conditions in terms temperature (150-200 °C) time (5-16 with three density levels...
