Liquid biodegradable plastic additive offers competitively priced solution for plastic manufacturers

A new liquid additive that has 13% solid contents and 100% active ingredients to be used in most major polymers has been developed by BioSphere. Initially developed for companies in Japan, the liquid biodegradable plastic additive was soon released worldwide due to the demand of liquid formulations. This groundbreaking technology, tailored for the plastic and paper industries, is priced competitively for the market; from US$7-12/kg. The liquid biodegradable additive is utiized at 1% by total weight of the final product and is easily mixed with many different polymer types, including polyurethanes. The biodegradable additive has a low viscosity, high heat thermostability and is clear, allowing for multiple different avenues for end uses. BioSphere’s unique formulation allows the microorganisms to consume the polymer chain by the addition of the additive at 1% by load weight. The microorganisms initiate hydrolysis which is the first phase of biodegradation in the environment. By adding in the BioSphere additive, multiple metabolic pathways are allowed for the microorganisms. Metabolic pathways are the pathways which microorganisms have the ability to break down the polymer and utilize the carbon content for energy and survival. Although plastic can biodegrade over a very long period of time by microorganisms, the polymer chain is so tightly packed together that the microorganisms find other food sources within the area which are easier to consume. With the BioSphere additive the microorganisms will not pass by the nutritious meal that is found within the polymer chain and they will begin to colonize creating a thriving colony on the plastic products. After the colony begins to consume the plastic, the products will turn into CH4, Co2, biomass and water.

New LiquiSol color and additive system for polymers is a full system designed to integrate liquid into our customers' operation, not as a replacement to color resin concentrates, but as alternatives for specific manufacturing processes. PCC (Plastics Color Corporation), a leading supplier of color concentrates, claims there are often advantages of liquid over solid concentrates including lower let down ratios, better thermal stability, reduced storage space requirements and versatility in formulations. The LiquiSol system includes: 

  • A complete analysis of a manufacturing center by PCC’s liquid experts, including a cost-benefit analysis
  • The latest in liquid color technology including pumps, vessels, storage and supply systems
  • Training for production staffs to ensure immediate benefit
  • Customized products that include colors, multiple additive dispersions, functional and performance enhancers
