100% Nature Biomass Based Biodegradable Resin - UNIDO

Possible applications

The company is the world’s best are resins biodegradable supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

  • Replace petroleum-based plastic material and products.
  • Utilize local biomass waste such as waste wood, wastepaper, starch etc.
  • Prevent from plastic pollution on land and in the ocean.
  • Technology is roughly all established so that they can apply general injection molding machine, film machine, blow molding machine etc. with normal procedure. Normal extrusion machine can be utilized for biodegradable resin pellets production too.

    Competitive advantage

                                                Table 1. Comparison of biodegradable resin with competitors

    1. Other competitor’s biodegradable resin is made of petroleum or partly petroleum. Our resin is made of 100% nature biomass and no petroleum is used.
    2. By making composite with nano cellulose, molding property can be improved as well as biodegradability, mechanical strength, foaming properties etc.
    3. Biodegradable molded products are normally made of petroleum or partly biomass materials. Despite our resins consist of 100% nature raw  material, people can manufacture molded products with conventional machines and procedure with our resin in mass production level, because of the improved molding property.
    4. Some of biomass wastes cost money to discard or dispose. We utilize various type of biomass waste resources such as waste wood, paper, bamboo, rice husk, coconut shell, bagasse, cassava, sugarcane leaf, starch etc. By doing this procedure, we can reduce discard cost and resin cost, and also recycle these types of biomass resources efficiently.
    5. Some biodegradable resins can be made of 100% nature material; PLA and starch based biodegradable resin. However, they derive from foodstuffs such as corns, sugar canes, potatoes etc. and it might be a problem when food shortage occurs in the future due to population explosion. However, one of our biodegradable resin can be made from cellulose, non-edible biomass. Not to mention this cellulose-based biodegradable resin does not derive from petrochemical, but 100% nature raw material.
    6. We make resin material, nano cellulose, composite material as resin pellets and molded products all by ourselves. So that our technology and knowledge have become better than other companies.

    Performance

    1. By making composite with nano cellulose, mechanical strength of biodegradable resin becomes stronger. For example, tensile strength of starch based biodegradable resin is approximately 8 MPa. When about 23% of nano cellulose is mixed to make composite, tensile strength becomes approximately 20 MPa. In addition, bending strength, elasticity increases. In contrast, MFR and impact strength decreases which needs to be improved with further challenge and research.

    2. For cutlery manufacturing as example, with just PLA, people can manufacture PLA molded products less than 100 pieces per day. However, with our PLA + nano cellulose based biodegradable resin, they can manufacture over several thousand per day due to the improved molding property.

    3. Compared to PLA itself, by making PLA + nano cellulose composite, biodegradability increases more than twice in the measurement time over a month.

    4. By mixing concentration of 1-2 % of nano cellulose with PLA, foaming property increases. Foam (gas bubble) size of 30-80 μm were observed with only PLA. With 1-2 % of nano cellulose, foam size became approximately 10μm and moreover, distributed uniformly in the resin. Bubble can be observed where nano cellulose trace can be seen. This means nano cellulose may have functioned as foam nucleating agent.

    Technical maturity / Past record of introduction

    From 2017, we have been selling our biodegradable resin products mainly as pellets form. We have sold more than several hundred kilograms in total, to over 70 customers in Japan and to many countries including Thailand, Vietnam, Philippines, India, China, Spain, Netherland, France, USA. We have been selling mainly as samples to several ~ dozens of kilograms to each country. Sold products are mainly PLA and starch based biodegradable resins composite with nano cellulose and biomass waste. Cellulose based biodegradable resin is made very recently although we start supplying this material too recently.  
    We started to obtain more repeat orders and order quantity. These are increasing every month.
    We also started to sell several pieces of molded products (spoons, forks, knifes, plates, cups etc.) in 2020, which have been strongly demanded.

    5 patents have been applied in Japan.

    How Environmentally Friendly Is Resin? What to Know About the Popular Crafting Material

    It should come as no surprise that many people who live sustainably also tend to dabble in DIY projects. After all, you sometimes have to get creative to find more sustainable solutions to everyday products. Especially during the pandemic, many zero-wasters also have taken up do-it-yourself hobbies like macrame, knitting, crocheting, cross-stitching, sculpting, or even making their own jewelry, keychains, and whatever else with resin. But is crafting with resin truly sustainable?

    While we may think of do-it-yourself projects as largely sustainable, it really depends on the materials used. With all things, if it’s virgin materials we’re talking about, it may not the most eco-friendly option. However, if you’re upcycling or using secondhand materials – like resin made from recycled materials – it's definitely a greener option. Keep reading for the full low-down on resin.

    What is resin?

    Popular in arts and crafts spaces, resin is an organic liquid that requires a hardener to create a plastic-like material, according to Resin-Expert.com. Resin is often used to make durable castings, floors, and countertops; but in the do-it-yourself world, you can make just about anything with resin or epoxy resin: jewelry, coasters, ashtrays, dog tags, keychains, bookmarks, hair clips, encased dried and pressed flowers, and more.

    Essentially, there is eco-friendly resin and there is non-eco-friendly resin. Some resins are synthetic — these are not eco-friendly, nor are they biodegradable. These synthetic resins, according to ExpandUsCeramics.com, are made from fossil fuels and as such, have to be treated and used very carefully (as in if burned improperly, they release toxins into the atmosphere).

    Is resin biodegradable?

    That said, eco-friendly resin exists, and some of it is recyclable. Black resin from Terra Cast, for example, is made from 100 percent post-consumer recycled materials. The site says, “Regardless [of] if the starting materials are recycled or not, our resin begins in pellet form as small chunks of Linear Low-Density Polyethylene. We get recycled resin from manufacturers such as Dow Chemicals and Exxon Mobile."

    This resin is made from recyclables and is recyclable itself. It’s also meant to be extremely durable, so it lasts a long life before having to be recycled, and harms absolutely no natural resources. That said, though, it isn't biodegradable.

    In fact, most resin isn’t biodegradable. But that’s not to say that biodegradable resin does not exist — you just have to look for it. After all, in 2011, chemists developed a synthetic resin that was 100 percent biodegradable and recyclable, made from non-toxic and non-hazardous raw materials. How about that?

    There are other sustainable alternatives to resin.

    If you are looking to craft with resin or resin-like materials, there are a few more sustainable alternatives for you to consider. Ecopoxy is a bio-based, plant-based epoxy “resin” specifically (and sustainably) made for woodworking. 

    As mentioned above, the Terra Cast resin is another sustainable option as all of its colors are made from mostly recycled materials and its black resin is made from 100 percent post-consumer recycled materials. Other resin substitutes include hard plaster or concrete (if you’re casting), alabaster, slush latex, or metal. But when it comes to ethics and sustainability, each material comes at (some kind of) cost, and requires additional research.
