Spent Coffee Ground Tannin

    Project Code: 243
    Spent coffee grounds account for 6,000,000 tons/year worldwide, so there is an urgent need to provide a method to handle these toxic wastes. The isolated spent coffee ground tannin is a new green technology since it replaces the petroleum-derived phenolic materials that account for the annual production of 20,000 metric tons. It can replace the green plant-derived tannin which is involve deforestation and against the Kyoto Protocol

Project Overview

This invention focuses on the reuse of toxic spent coffee grounds (SCG) as a renewable tannin resource. By applying the developed simple and low cost method/process, the isolated SCG tannin with a high recovered yield and reactivity, can be used to replace the non-renewable petroleum-derived phenolic materials in the production of adhesive, plastic and polyform. In other words, the SCG can be directly used as the renewable raw material in the manufacturing of these polymeric products, which, in turns, facilitates the valorization of the discharged SCG for environmentally friendly production of green product that capable to benefit the society and the nation due to its tendency to improve various aspects of life (environment and health).

This invention exerted a vital step towards waste management, as it solves the ecological problem related to the disposal of toxic and land-polluting SCG and also in providing a new green raw material for different industrial applications. Features include:

  • This invention provide a biomass-derived tannin by using the municipal waste, namely spent coffee grounds (SCG) as a renewable resource, which is never been explored and reported by other experts.
  • Low cost and eco-friendly products (such as adhesive, plastic, polyform) can be produced by using the spent coffee ground tannins that acquired from the discharged wastes (Spent coffee grounds).
  • Provide a new low cost green material to replace the costly non-renewable petroleum-derived phenolic materials.
  • A new method to handle toxic spent coffee grounds
