| Cellulose plastics are  bioplastics manufactured using cellulose or derivatives of cellulose. Cellulose  plastics are manufactured using softwood trees as the basic raw material. Barks  of the tree are separated and can be used as an energy source in the  production. To segregate cellulose fiber from the tree, the tree is cooked or  heated in a digester. As per Transparency Market Research, resins and lignins  are produced as a byproduct in the digester. The byproducts can be used as a  fuel or as a feedstock in the production of other chemical products. The pulp  such produced is comprises hemicelluloses and alpha cellulose.  Pulp is  then treated with bleaching chemicals to eliminate any traces of resins and  lignins and to reduce the hemicelluloses content of the pulp. The processed  pulp contains water which is removed from the pulp before processing the pulp  with high alpha cellulose content. The pulp is then used in the production of  cellulose esters used in the production of cellulose plastics. Cellulose esters are  produced by reaction of the processed pulp with certain acids and anhydrides in  varied concentrations and temperatures depending on the end user application.  The properties and chemical composition of cellulose esters is dependent on the  acids and anhydrides used in the production process. Butyrate, acetate and  propionate are among the major types of cellulose esters. Cellulose acetate is  the dominant product type for cellulose esters and the trend is anticipated to  continue during the forecast period. Major applications for cellulose plastics  include thermoplastics, extruded films, eyeglass frames, electronics, sheets,  rods, etc. Molding materials is the most dominant application segment for  cellulose plastics and the trend is expected to continue for a foreseeable  future. Plastic is produced mainly  using non renewable sources such as crude oil and its several derivatives owing  to which, the carbon footprint is high during the production of plastics.  Moreover, other issues such as biodegradability and other environmental hazards  associated with traditional plastics have led to surge in number of regulations  to control the use of plastics. The regulations imposed on plastics have led to  surge demand for bio based plastics and thus has been driving demand for  cellulose plastics. Furthermore, increasing demand for electronics products  such as transparent dialers, screen shields, etc. has been among foremost  growth drivers for cellulose plastics market. Softwood is the dominant raw  material used in the production of cellulose plastics and increasing number of  deforestation regulations is a major restraint for the market. Easy  availability and low cost of conventional plastics is also among major  restraint for cellulose plastics market growth. Moreover, high efficiency and  comparative cost benefit of conventional plastics over cellulose plastics has  restrained market growth for cellulose plastics. Increasing research and  development to produce high efficiency and low cost cellulose plastics is  anticipated to offer huge growth opportunity in cellulose ester market. Eastman Chemical Company has  introduced Eastman TRĒVA™, a breakthrough in engineering bioplastics that help  global brands concurrently meet their sustainability and performance needs in  today’s rapidly evolving marketplace. TRĒVA™’s composition is about half  cellulose, sourced from trees derived exclusively from sustainably managed  forests that are certified by the Forest Stewardship Council (FSC). The new  material is BPA-free and phthalate-free. Its excellent flow rates, durability  and dimensional stability allow for less material usage, thinner parts, and  longer product life, enhancing lifecycle assessments. TRĒVA™ offers excellent  chemical resistance, standing up better than other engineering thermoplastics  to some of the harshest chemicals, including skin oils, sunscreens, and  household cleaners. The material’s low birefringence means eliminating the  unwelcomed rainbow effect some plastics experience with polarized light,  improving the user experience with electronic device screens and retail  displays.Excellent flow characteristics also enable design freedom, allowing TRĒVA™ to  be used with complicated designs and in filling thin parts. Under  recommended processing conditions, recent thin-wall 30 mil spiral flow testing  shows that TRĒVA™ flow rates are significantly better than polycarbonate and  polycarbonate/ABS blends, and comparable to ABS.
 TRĒVA™ is designed to allow for superior surface gloss, clarity and warm touch  and feel, enabled through a combination of the base material and Eastman’s  technological expertise. The material also boasts great color saturation, and  superior secondary processing and decorating capability, creating additional  design and branding options.
 TRĒVA™’s superior combination of sustainability and safety benefits, end-use  performance improvements, and design and brand flexibility make it ideal  material choice for the following applications:
 * Eyeglass frames, wearable electronics, headphones, and many  other personal devices that come in direct contact with the skin;
 * Electronic display applications, such as lenses and covers, that  consumers need to see through;
 * Electronics, housings, intricate cosmetics cases, and other  products with high design and complex specifications;
 * Automotive interior components wherein chemical resistance and  aesthetics are desired;
 * And other demanding applications with high sustainability and  safety requirements.
 AkzoNobel and agro-industrial cooperative Royal Cosun have partnered to  develop novel products from cellulose side streams resulting from sugar beet  processing. The partnership will combine Royal Cosun's specialist knowledge in  separating and purifying agricultural process side streams with AkzoNobel's  expertise in the chemical modification of cellulose.Cellulose-based products  resulting from sugar beet processing, addressing the need for more sustainable  raw materials from a variety of industries, such as food and healthcare, as  well as the coatings and construction sectors."      In 2014, AkzoNobel announced it had  teamed up with Deloitte and  a handful of other Dutch stakeholders to investigate the potential for  producing chemicals from beet-derived sugar feedstock, as part of ongoing  industry efforts to replace increasingly scarce non-renewable raw materials.  This new partnership with Royal Cosun illustrates that potential.
 As well as highlighting  Royal Cosun's focus on the bio-based economy, the partnership also underlines  AkzoNobel's Planet Possible agenda, which includes ongoing efforts to develop  and introduce sustainable, bio-based products that contribute to a circular  economy.      Thankfully, more and more  companies are getting wise to the wonderful ways of circular models by putting  previously wasted materials to good use. Last year, Biome Bioplastics began a major  development program to significantly accelerate the global bioplastics market with the production of novel target  materials, including a fully bio-based polyester. The project aims to harness  industrial biotechnology techniques to produce bio-based chemicals from lignin — an  abundant waste product of the pulp and paper industry — at a scale suitable for  industrial testing. The availability of these chemicals could revolutionize the  bioplastics market.
 
 Plant cellulose may  potentially provide a renewable and biodegradable alternative to polymers  currently used in 3D printing materials, a new study has found-
 “Cellulose is the most  important component in giving wood its mechanical properties. And because it is  inexpensive, biorenewable, biodegradable and also very chemically versatile, it  is used in a lot of products,” said lead researcher, Sebastian Pattinson of  Massachusetts Institute of Technology (MIT) in the US. “Cellulose and its  derivatives are used in pharmaceuticals, medical devices as food additives,  building materials, clothing, all sorts of different areas. And a lot of these  kinds of products would benefit from the kind of customisation that additive  manufacturing- 3D printing enables,” Pattinson added.      When heated, cellulose  thermally decomposes before it becomes flowable. The intermolecular bonding  also makes high-concentration cellulose solutions too viscous to easily  extrude, researchers said. To avoid this problem, researchers chose to work  with cellulose acetate - a material that is easily made from cellulose and is  already widely produced and readily available. Using cellulose acetate the  number of hydrogen bonds in this material was reduced by the acetate groups. Cellulose  acetate can be dissolved in acetone and extruded through a nozzle.
 As the acetone quickly  evaporates, the cellulose acetate solidifies in place. A subsequent optional  treatment replaces the acetate groups and increases the strength of the printed  parts. “After we 3D print, we restore the hydrogen bonding network through a  sodium hydroxide treatment. We find that the strength and toughness of the  parts we get are greater than many commonly used materials,” for 3D printing,  including acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA), said  Pattinson. The research was published in the journal Advanced Materials  Technologies.
