Biodegradable Controlled Release Matrix Tablets for Environmental Applications

Abstract/Technology Overview

Using a proprietary matrix encapsulation technique, active ingredients are incorporated into a matrix made from a biodegradable polymer. Pesticides, biocides, corrosion inhibitors, enzymes, and bacteria are just some of the examples of the kinds of actives that can be encapsulated. Then the polymer is formed into tablets of various shapes and sizes. Each tablet can deliver its active ingredients into the environment over a predetermined time frame, with precisely controlled dosages to ensure the desired treatment effects. At the end of the treatment period the matrix is completely and safely degraded.

Technology Features, Specifications and Advantages

  • Extrusion-based process

  • Processing at ambient temperatures (20 - 30˚C)

  • Processing at low pressures (5 - 50 psi)

  • Ability to incorporate actives in liquid, solid, and gel states, with payloads of up to 80%

  • Offers a high degree of release profile manipulation

  • Encapsulating matrix is entirely biodegradable

  • Matrix can be made porous for applications requiring buoyancy

  • Matrix can be produced in any shapes and sizes with a regular cross section

  • Simple and easy to scale up

Potential Applications

  • Agriculture - for dosing pesticides and fertilizers 
  • Aquaculture - for dosing nutrients

  • Oil mining - for dosing water conditioning agents 

  • Water treatment - for dosing biocides
