Adhesives from Waste Protein Biomass for Oriented Strand Board Composites: Development and Performance

Abstract

The primary goal of this work was to develop a novel adhesive technology platform for oriented strand board (OSB) using waste animal protein extracts, as feedstock. In this research, a hazardous animal processing waste was thermally hydrolyzed, and the proteinaceous fractions were recovered and modified into an adhesive. The adhesive developed as such was formulated for OSB adhesion applications, and the OSB performance was also evaluated. Performance results showed that the OSB specimens made with up to 60% by weight of protein hydrolyzate based adhesive met the Canadian Standard Association (CSA O437.0-93) requirements for commercial applications. Based on the intermediate moisture resistance results observed, the recommended use of these boards could be for relatively low moisture environments.

Valorization of rendering industry wastes and co-products for industrial chemicals, materials and energy: review

“…Bone glues have been traditionally used in carpentry and blood used as an additive in plywood glue-mixes (Pizzi, 2006). Modern chemical modifications have built on this early knowledge and allowed the development of engineered wood adhesives based on bovine and porcine blood meal (Yang et al, 2006), blood protein extract (Lambuth, 2003), whey protein (Wang et al, 2011), casein (Lambuth, 2003), spent hen (a by-product of the poultry industry) protein extract (Wang & Wu, 2012), meat and bone meal protein extract (Park et al, 2000), hydrolyzed SRM extract (Mekonnen et al, 2014). Historically, animal protein-based glues were the adhesives of choice for paper manufacture and converting, bookbinding, text sizing, abrasives, gummed tape matches, and a variety of other applications (Pearson, 2013).…”

Pelletization of Torrefied Wood Using a Proteinaceous Binder Developed from Hydrolyzed Specified Risk Materials

“…One of the CFIA approved methods of SRM disposal is thermal hydrolysis at minimum conditions of 180 • C and 1200 kPa for 40 min per cycle [32]. In this study, thermal hydrolysis of SRM and recovery of hydrolyzed protein fragments (referred to as peptides hereafter) from the hydrolysate was achieved following our standard protocol [24,26,28,33]. A high-temperature and high-pressure stainless-steel Parr reactor vessel (5.5 L capacity, Parr 4582, Parr Instrument Company, Moline, IL, USA) equipped with Parr reactor controller (Parr 4848, Parr Instrument Company, Moline, IL, USA) was used for thermal hydrolysis of SRM.…”

“…Lyophilization of the aqueous fraction afforded a tan colored proteinaceous cake representing 34 ± 2% of the feed material. Prior to hydrolysis, the SRM sample was considered as biohazardous material, and was handled by practicing the safety measures as described in previous reports [24,26,28,33].…”

“…Over the years, our group has developed a technology platform for chemical conversion of specified risk materials (SRM), a proteinaceous waste from the rendering industry, into valuable products such as adhesives [24][25][26], plastics [27], and composites [28]. Recently, we demonstrated that adhesive formulations consisting of 78% peptides and 22% polyamidoamine epichlorohydrin (PAE) resin (dry weight basis) satisfied the performance requirement of the American Standard of Testing and Materials (ASTM) as a plywood adhesive [24].…”

Carbon Dioxide–Derived Poly(propylene carbonate) as a Matrix for Composites and Nanocomposites: Performances and Applications

“…Polymers are essential materials used in a variety of applications ranging from packaging, containment, clothing, electronics, paints, automotive parts, wind turbine blades to airplane parts. The traditional petroleum‐based plastics industry is facing three grand challenges: i) environmental pollution concerns associated with plastic disposal with about 5 million tons of plastic waste per year, ii) natural limitation of petroleum resources in some geographies and depletion concerns in others, iii) health and safety of some polymers especially in packaging, coating, and biomedical uses . To mitigate these challenges, efforts are directed toward developing polymers from renewable resources, development of biodegradable polymers, and biocompatible polymers with cost and performance structure comparable to those of synthetic industrial polymers …”
