Castor Oil Based Biodegradable Foam Plastics

Posted on by
1

This work – http://pubs.acs.org/doi/abs/10.1021/bm7009152, explains a approach  for preparing biodegradable plastic foams with a high content of castor oil. Castor oil is reacted with maleic anhydride to produce maleated castor oil (MACO) without the aid of any catalyst. Then plastic foams were synthesized through free radical initiated copolymerization between MACO and diluent monomer styrene. With changes in MACO/St ratio and species of curing initiator, mechanical properties of MACO foams can be easily adjusted. In this way, biofoams with comparable compressive stress at 25% strain as commercial polyurethane (PU) foams were prepared, while the content of castor oil can be as high as 61 wt %. The soil burial tests further proved that the castor oil based foams kept the biodegradability of renewable resources despite the fact that some petrol-based components were introduced.

Posted on by
Reply

Wastberg , a Swedish lighting company, that manufactures economic and energy efficient lighting solutions, has designed a lamp that uses a plastic made with castor bean oil.  Called the Winkel w127, the lamp uses LED lights that are designed to shine for 50,000 hours.

Winkel w127 is manufactured of solid fiberglas reinforced biopolyamide, which is made out of castor oil.

Castor Bean Plant – An Important Source for Bio based Flooring

Hello readers,

This post at Castoroil.in briefs a few excerpts from an article at the Contract Flooring Journal, which was narrated on biobased flooring. The author explains his experience at Ecobuild, which is one of the world’s biggest events for sustainable design, construction and the built environment and presents interesting insights on biobased flooring and sustainability.

The author sees castor bean plant as one of the most important plant sources of bio-chemicals. Some of the companies using castor based flooring products, which exhibited at the show include :

  • Interface- Fotosfera ( Offers two pile weight micro tufted or pattern loop carpet tile products which features nylon 6:10 pile of which 63% is castor oil based)
  • Vorwerk (Offers ‘RE/COVER green’ which is a bio chemical based resilient florring targetted at the vinyl flooring market)

The author also brings his views on Desso, a company which makes its products, using the concept of “CRADLE TO CRADLE” – ( A biomimetic approach to the design of products and systems) Desso has partnered with Aquafil nylon recycling facility and manufactures Econyl, a 100% recycled yarn in 60% of its carpet tile range. Desso has also developed its equipment and capability to process more than 3000 tonnes of used carpet material through its Take Back Programme.

Sebacic Acid For Type 2 DiabetesTreatment

Researchers at Nestle – a leading Swiz based nutrition and health company – had discovered that sebacic acid (a 10-carbon dicarboxylic acid and a derivative of castor oil) significantly reduced hyperglycemia  in type 2 diabetic subjects.

Researchers first conducted a study with people with type 2 diabetes. The men and women were given a meal containing 0g sebacic acid (control), 10g of sebacic acid in addition to the meal, or 23g of sebacic acid in substitution of fat in the meal. Researchers were interested to find that postprandial glycemia decreased by 42% in the group given the 10g sebacic acid, while the group who consumed 23g experienced a 70% decrease. Additionally, the rate of peripheral glucose appearance was significantly reduced in the 23g sebacic acid group, suggesting decreased glucose absorption and/or improved peripheral glucose uptake.

Methods of Production of Novel Castor Oil Derivatives

Posted on by

This research carried out at the National Center for Scientific Research, France discusses the production methods of the castor oil derivatives.

There exist different approaches for synthesizing polymers based on vegetable oils. The first most widespread one consists of considering triglycerides as base materials, the latter may be epoxidized and for example alcoholized or hydroformylated in order to make them functional and polymerizable.

An oil is a mixture of triglycerides (triesters) formed by condensation of fatty acids and of glycerol. The high number of fatty acid types (up to 24) present in each fat and the multiple possibilities of their combinations with glycerol molecules have the result that the fats are highly complex mixtures of compounds, the properties of which vary from one oil to another. The nature of the triglycerides may therefore vary within a same oil.

The reactive sites present in a triglyceride are mainly double bonds and ester functions. The reactivity of double bonds allows introduction of hydroxyl functions, thereby allowing access to polyhydroxylated monomers. Nevertheless, it is impossible to obtain triglycerides having perfectly defined structures and functionalities.

The present study provides a method for preparing compounds from vegetable oil, with which the aforementioned drawbacks may be overcome. The research work also attempts to provide a method for preparing compounds derived from vegetable oil, comprising the use of catalysts better fitting environmental expectations than most of the homogeneous catalysts used and which limit the secondary reactions.

Production of Polypropylene Glycol Polyricinoleate, Butanediol Polyricinoleate,Butanediol Polyricinoleate, Butanediol Esters, Butanediol Diesters , Propanediol Esters have been discussed.

Zeal Optic’s Sunglass Frame from Castor Derivatives

Posted on by

US based Zeal Optics, developed its sun glass frames, using a bio-based plastic made from castor bean oil. Zeal Optics uses castor oil to produce Z-ResinTM, which makes up the foundation of their entire line of frames (as opposed to using crude oil, which is what sunglass frames are traditionally made from).

Zeal Optics Castor Plant

The company’s bio based lens,is said to be the first lens of its kind that provides an ecological alternative to crude oil based lenses. Currently ZEAL produces all their sunglass frames with Z‐resin, thus eliminating harmful crude oil from the manufacturing process.

Jayant Agro Organics Ltd, an Indian oleochemical company, have entered into a joint venture agreement with two Japanese firms – Mitsui Chemicals Inc and Itoh Oil Chemicals Co Ltd – for manufacturing castor oil based polyols. The firms are investing in the equity shares of Vithal Castor Polyols Pvt Ltd in the ratio 50:40:10 respectively.

This is a second deal announced by Jayant Agro Organics this year. In April 2013, Jayant Agro entered into an agreement with Arkema, a French chemical company, to form a strategic joint venture through its subsidiary Ihsedu Agrochem Pvt Ltd (Ihsedu). According to the JV agreement, Arkema will acquire around 25% equity stake in Ihsedu. The JV aims to develop castor oil production, which will provide Arkema long term, secure and competitive access to the strategic raw material for the manufacture of its bio-sourced polyamides.

DuPont, one of the world’s largest chemical companies, says that its performance plastics line will contain more than 50 percent renewable materials within 15 years. The company is exploring new technologies to make chemical monomers for basic plastics like nylon from carbon-based resources that can be rapidly regenerated.

Two of the three renewable materials in DuPont’s current performance plastics portfolio are based on non-food feedstocks. Hytrel comes from plant waste and Zytel RS comes from the castor bean plant.

Germany’s Worlee Cosmetics Launches Castor Oil Based Exfoliants

Posted on by
Reply

In Germany, Worlee Cosmetics has developed castor oil based WorléeBeads HCO, which can be used as a cosmetic rinse-off product, replacing PE and PP plastic micro particles as an exfoliant. The product is designed for exfoliation in rinse-off products such as facial scrubs, body scrubs and shower gels.

Due to their low particle size, plastic micro particles (100 – 500 μm) used in cosmetic applications can pass through filter plants and finally end up in great quantities in the oceans and from there to marine life and finally into the human food chain. Plastic micro particles finding their way to landfill may still be potentially harmful for decades due to the very slow decomposition of plastics. The concentration of the toxic, carcinogenic and hormonally acting substances caused by these plastic micro particles will only increases over time and the total risk and impact on humans and the environment has yet to be realised.

WorléeBeads HCO hence offers a safe and environmental friendly alternative.
