Background/Description

Bentonite clay is an abundant and naturally occurring mineral that results from the weathering and sedimentation of volcanic ash deposits. Its principal ingredient is calcium montmorillonite, a highly adsorbent, chemically inert, and non-corrosive substance. When mined from the ground, then processed and dried into the form of free-flowing granules, bentonite clay attracts and binds water vapour readily within its complex and highly layered structure, making it a highly effective desiccant. The material has many environmental and sustainability advantages because it is abundant, naturally occurring and has small carbon footprint.

The company that is responsible for ensuring the quality and shelf life of packaged products face a range of considerations when it comes to sourcing a desiccant that is right for their applications. With the growing interest in circular economy, the company is exploring innovation for the depositing or recycling of used desiccants that are packed in porous bags, single packets, and continuous strips.

Technology Specification

The desired technology can be eco-friendly packaging materials to simplify the recycling process, or a completely novel, sustainable format to incorporate the desiccants for various packaging applications, i.e. food, automobile parts, leather goods, electronic components, metals strips, etc.

The technology should:

  • Not reduce the original capabilities and performance of the desiccants
  • Be heat resistant and processable at high temperature, i.e. minimum 150°C
  • Not contribute to significant weight of the packaging system
  • Fabricable at low cost
  • Suitable to hold up to 1 kg of desiccants
  • Allow simplification of the recycling process

Preferred Business Model

  • Business Collaboration (Joint Venture, Distribution)
  • IP Acquisition
  • Licensing
  • Others
  • R&D Collaboration
