The Emerging Importance Of Bioplastics

I get disgusted. When I separate my household waste into glass/metal, paper, compost, and the rest. When I look at the rest, I am angered that it is mostly made up of packaging plastics. Plastics made from petrol-based products that do not degrade, and hang around out environment forever – including threatening sea life. There must be a solution to this. Research is showing that mixing petrol-based plastics with plant cellulose fibers may be an answer to the accumulation of plastics in our environment.

Let’s Start with Plastic Pollution FACTS

  • As of 2018, 335 million tons of plastics are produced globally each year.
  • 45% of all plastics are produced in the United States.
  • 29% of plastics produced in the US are used for packaging (15% building, 14% consumer).
  • The packaging market, in the United States alone is worth $100 billion, a quarter of the global market.
  • In the United States over 60 billion pounds of plastic are discarded into the waste stream each year (from 4 billion in 1970). Most of this is in Municipal Solid Waste.
  • One-half of all discarded plastic comes from packaging. Almost one-third comes from packaging that is discarded soon after use.
  • Beach litter is 40-60 percent plastic, much of which often floats in from the sea. Such beach litter is hazardous to birds, fish and animals who die from ingesting it or becoming entangled in it.
  • Wide-scale postconsumer recycling of plastics is relatively new. Modern plastics are becoming harder to recycle.

There is much research being conducted of mixing petrol-based plastics with plant based cellulose fibers. Experiments world wide have shown that, for example, polypropylene by itself will never degrade. However, if mixed with any plant based cellulose, such as rice, hemp, or trees, it will degrade based on the amount of cellulose in it. The more cellulose the faster it degrades.

As an example, a Cellulose Fiber Research paper showed that a 50% content of cellulose fibers significantly increases the rate of decomposition of polypropylene. Hybrid compositions are being constructed that are totally replaceable for many applications – even for food grade or pharmaceutical applications, even 3D printing.

So what are we waiting for. The planet is suffocating in plastic. Let’s move forward quickly with an alternative.


  1. I can SO relate to this. It makes me sad how much plastic waste is finding its way toward oceans and how much of it breaks down into carcinogenic compounds. You are right! The world IS suffocating. No time to lose on switching up our consumer habits.
