OXYGEN BARRIER FILM
20210207324 · 2021-07-08 · ·

The present invention relates to a process for improving the strechability of films comprising high amounts of microfibrillated cellulose (MFC) without negatively impacting the oxygen barrier properties. According to the present invention, a film is formed from a suspension comprising microfibrillated cellulose having a broad size distribution.

Method for cooling and detoxifying biomass
20210207185 · 2021-07-08 ·

The present invention relates to an improved method and device for treating biomass in which thermally treated biomass is discharged from a pressurized reactor and introduced into a blow tank, wherein the absolute pressure in the blow tank is maintained below atmospheric pressure. The slurry of biomass separated in the blow tank is then enzymatically treated.

LIGNOCELLULOSIC COMPOSITES PREPARED WITH AQUEOUS ALKALINE AND UREA SOLUTIONS IN COLD TEMPERATURES SYSTEMS
20210207320 · 2021-07-08 ·

Unique, inexpensive, and strong biocomposites are obtained from blending cellulose matrix materials pith lignocellulosic reinforcement materials with the aid of alkaline aqueous solvent and cold temperatures. These lignocellulosic composites (LCs) are produced without use of any thermoplastic resins, adhesives, catalysts, plasticizers or d chemical or physical procedures. The LCs include a matrix and a reinforcement material. The matrix is a cellulose material (e.g., cotton, hemp, flax, or wood) that is liquefied using an aqueous alkaline solvent solution under cold temperatures to more readily adhere and or incorporate/encapsulate the lignocellulosic reinforcements (wood chips, fibers, and other lignocellulosic sources).

PERSONAL CARE COMPOSITION
20210007941 · 2021-01-14 · ·

Disclosed are personal care compositions comprising a fibrous material of natural origin and obtained from plants. The fibrous material comprises micro-scaled and/or nano-scaled fibril agglomerates. Such compositions show pleasant skin feel and comfort during and after application, as well as fast drying and fast absorption into skin. The compositions obtained are also particularly well suited for the topical delivery of cosmetic and pharmaceutical active substances into skin. Additionally, a method to obtain said personal care composition is disclosed.

PRETREATMENT WITH LIGNOSULFONIC ACID
20210010036 · 2021-01-14 ·

A process for converting lignocellulosic biomass to glucose or ethanol includes subjecting the lignocellulosic biomass to a lignosulfonic acid pretreatment, wherein the lignosulfonic acid has a concentration of sulfonate groups in acid form that is greater than 0.02 mol/L and a total amount of sulfur dioxide is greater than 15 wt % based on dry weight of lignocellulosic biomass.
