“…Hayes went on to write a review for the use of lipase catalysis (Hayes 1996) with a few examples of estolides formed from lesquerella and castor fatty acids. Kiatsimkul et al, (2008) used C. rugosa or C. antartica lipases to synthesize homo-oligomeric estolides of ricinoleic acid both under vacuum and atmospheric pressures at 60 o C. The reaction required 5 days to yield ~50% estolide which consisted of dimmers and trimers. These estolides were later used to open epoxidized soybean oils to make polyols.…”

“…cellulose and cotton) including biodegradation, mechanical strength, impact resistance, transparency, colorability, fabricating versatility, moldability, and di-electric strength (Kopinke et al, 1996, Calmon et al, 2000, Sato et al 2001, Fischer et al, 2008and Jinghua et al, 2009, Mostafa et al, 2016. In recent years, the development of biodegradable materials from renewable natural resources has received increasing attention, particularly in EU countries (Davis and Song, 2006) et , Cateto et al, 2008and Kiatsimkul et al, 2008. If properly managed, this will reduce their environmental impact upon disposal (Davis and Song, 2006) and, also, it will be technically and economically practicable (Tanaka et al, 2008).…”

The objective of this study was to determine the biodegradability of bioplastic materials -sponge cloths -available on the European market. They are labeled as 100 % biodegradable but not certified as compostable. The test was carried out in real composting environment. The project duration was 12 weeks. The emphasis was put on discovering whether the sponge cloths are biodegradable or not. Based on the results, it can be concluded that sponge cloths have decomposed completely (sample C and sample D). Samples A have decomposed but exhibited slower degradation rate. Samples B exhibited the higher degradation rate. The main conclusion from this study is that biodegradation of bioplastics materials strongly depends on both, the environment where they are placed and the chemical nature of the material.

Soybean oil has been an attractive starting raw material for the synthesis of prepolymers or monomers to produce a wide range of different polymers and chemicals.…”

Polymers derived from plant oils have attracted major commercial interest and significant attention in scientific research because of the availability, biodegradability, and unique properties of triglycerides. Triglycerides rich in unsaturated fatty acids, such as soybean oil (SBO), are particularly susceptible to chemical modification for desired polymeric materials. Soy-based polyols are important industrial prepolymeric materials that use renewable resources; and can be produced or derived through different processing routes. This review paper discusses previous and recent researches about chemical and biochemical polymerization processes to produce soy-based polyols as prepolymers for the production of polyurethane materials in the form of foams (rigid or flexible) and elastomers. The central goal of these research fields is to find effective reaction routes to increase both equivalent weight and hydroxyl functionality of soy-based polyols while taking into consideration the simplicity and economics of these processes.
