Due to increasing environmental concerns and decreasing petroleum resources, many renewable sources are being used for the development of bio-foam materials and composites instead of petroleum-based foams. Bio-renewable foams are a result of almost 20-30 years’ study and pilot scale production in the world, they provide not only a sustainable material source but also have a stable competitive price compared with current commercial origin. In addition, life cycle assessments have shown that these renewable materials have less environmental impact, there is no harmful emissions or by-products and no wastes are created during their processing. The whole products and processing are CO2 negative influence and pass the strictest environment regulations. It really confirms that bio-renewable foam provides a more environmentally friendly route to produce foam materials. This Special Issue "Renewable Foam Materials and Composites" covers the development of rigid, semi-rigid or flexible bio-foams using renewable biosourced materials. The scope of interests includes but is not limited to the following topics:

(1). Polyurethane foams with isocyanates or without (NIPU)

(2). Tannin foams

(3). Lignin/cellulose/hemicelluloe foams

(4). Vegetable oils foams

(5). Mono-and polysaccharides foams

(6). Other foams derived from renewable sources

Foams; Renewable; Bio and environmental degradation; Synthesis; Structure-property relationships; Processing; Recycling

  • Alcoholysis of Waste Polyurethane Rigid Foam and Its Modification with Lignin for Recovery
  • Abstract A bi-component alcoholysis agent containing propylene glycol (PG) and ethanolamine (ETA) was used to catalyst the degradation of the waste polyurethane rigid foam. The oligomer polyols obtained through degradation were used as raw materials to produce recycled polyurethane rigid foam composites with lignin as reinforcing filler. The effect of alcoholysis mass ratio on degradation was investigated by analyzing the viscosity, hydroxyl content and chemical structure of the degradation products. The effect of lignin addition on the properties of regenerated polyurethane rigid foam were investigated by analyzing water absorption rate, compressive strength, porosity, thermal stability, thermal conductivity coefficient, morphology and thermal… More

  • Preparation of Porous Materials Derived from Waste Mussel Shell with High Removal Performance for Tableware Oil
  • Abstract In this work, carbonized mussel shell powder (CMSP) was modified by alkyl polyglucosides (APG) and rhamnolipid (RL) to render porous biomass a lipophilic surface, which was innovatively utilized as an environmentally friendly tableware cleaning material. The modified method was two-step hydrotherm-assisted synthesis. A contact angle meter was used to determine the surface hydrophobic property of modified samples (MTAR). The pore and the surface structure of CMSP and MTAR were characterized by BET, SEM, XRD, FTIR and XPS. The effect of removing oil was tested by gravimetric method. The results showed that the surface of MTAR was more porous and fluffier… More

  • Effect of Post-Added Water Amount on Pre-Concentrated Bark Foaming Materials by Mechanical Stirring
  • Abstract In this study, pre-concentrated bark, furfuryl alcohol and other biomass raw materials were used to prepare foaming materials by high-speed mechanical stirring without using a foaming agent. We investigated the effect of the postadded water amount on the properties of foaming materials. In particular, we determined basic physical properties of these materials, including the limiting oxygen index (LOI), porosity, thermal conductivity, thermogravimetric analysis, pore size distribution, and microstructure. The results of scanning electron microscopy (SEM) indicated that the pore size distribution was uniform and the pore size increased with increasing water volume. Thermogravimetric analysis (TG/ DTG) showed that when the… More
