Plastic Pollution Challenge

Combating a global problem of plastic pollution through local solutions.  60% of  global ocean plastics originate from Indonesia, China, the Philippines, Vietnam and Thailand.  These same countries, are also home to 25% of the world’s brewers’ spent grains, a by-product in food manufacturing. Alterpacks is able to take this raw material that is currently being used as animal feed, fertilizer or discarded in landfills, to replace one-third of the household plastic packaging needs in these same countries. 


Using by-products from food manufacturing and agricultural waste to create a  new material that replaces plastic packaging.  


    Valorisation of food and agricultural waste to create bio-resins that can be used in standard plastic manufacturing machines to replace petroleum based resins and create food containers. The current raw material is brewers’ spent grains – malt and cereals thrown out in beer brewing, milo and cereal production.  This raw material may be replaced with agricultural waste such as coconut husks.  Alterpacks have developed an energy saving method that requires low heat and existing machines to create the pellets at scale.  The material is biodegradable and home compostable. This is important as plastic waste is often dumped in open ground, landfills or ends up as ocean plastic.


Alterpacks aims to combat plastic pollution by creating circular solutions where nothing goes to waste. 

  1. Processing 5 tonnes of coconut waste per month
  2. Replacing 125,000 plastic food containers per month
  3. End goal of making Mandalika a plastic free zone 
  4. Reducing the amount of food and plastic waste going to open dumps, incineration and landfills
  5. Substituting the demand for fossil-based resins and reducing CO2 emissions by more than 42 million tonnes
  6. Providing STEM learning
  7. Providing employment opportunities & equal opportunities

Business Model

  1. Work with the local community to find pickers to collect plastics, educate them on the plastics that are suitable, pay pickers fair wages for work.
  2. Work with local community to find coconut shell pickers and processors of the coconut.
  3. Build an Alterpacks eco-innovation factory in the Science Technology & Industrial Park (SITB) Banyumelek, Mataram City.
  4. Innovation factory will be built using recycled plastics and building materials.
  5. Innovation factory will house an education centre for STEM learning on recycling and use of waste in production.
  6. Innovation factory will create bioresins made from coconut waste to replace fossil-based resins for sale and export.

Traction & Key Metrics

Alterpacks is pre-revenue.  Traction and Metrics for the project will be:

  1. Feasibility study on area for development and construction
  2. Begin collaboration with community and start-ups for plastic pickers and coconut waste pickers
  3. Contracts to set up for coconut waste and processing
  4. Pellet refinement from coconut waste to create bioresins
  5. Test run of pellets
  6. Obtain international certification for food contact



  1. Start with coconut and agricultural waste in the region.  Continue to innovate and work with variations of this waste. 
  2. Switching out plastic use of food containers and expanding to other products
  3. Mandalika products and bioresins exported globally


Funding to Date: US$450,000

  • Temasek Foundation
  • Bootstrap

To raise: US$600,000

  • Pilot development with new coconut waste
  • Commercial run for pilot clients
  • Certification
  • Legal and contracts
  • Payment for pickers & waste collection

Alterpacks is supported by Singapore’s Temasek Foundation, Singapore Management University’s Institute of Innovation & Entrepreneurship (SMU IIE) and boot-strapped by the founding team.   The team aims to raise US$600,000 to fund the development of the coconut waste specific to Mandalika.
