We design out waste.

We start at the end and design out waste. Our vision is to minimise the environmental impact of product packaging. 

When working with companies to achieve zero waste packaging, the following principles help during the design process.

  1. Design for recovery;
  2. Optimise material efficiency;
  3. Design to reduce product waste;
  4. Eliminate hazardous materials;
  5. Use recycled materials;
  6. Use renewable materials;
  7. Design to minimise litter;
  8. Design for transport efficiency;
  9. Design for accessibility; and
  10. Provide consumer information on sustainability.

 

What is it made from?

Our home compostable packaging solutions are made from naturally occurring plant based materials such as FSC recycled paper, cellulose, GE-free corn and sugarcane. We are also working with a variety of experimental new materials, so if you are looking for a solution, we may have it. 


How does it breakdown?

Healthy soil is rich in microorganisms such as bacteria, fungi, enzymes and soil loving worms, who love to recycle organic waste into rich soil. Garden and food waste, paper, cardboard and home compostable packaging can all be placed in the home compost. 

When a warm aerated home compost is maintained at an ambient temperature of 20 - 30 degrees Celsius, the film/packaging material will break down. The composting process can be enhanced by cutting the packaging up into smaller pieces.

The certified home compostable film used in our packaging is made from cellulose, which is found in the cell wall of plants. Our cellulose is sourced from sustainably grown eucalyptus trees and once placed in the home compost environment, it is easily broken down into biomass, CO2 and water. The material is then safely reabsorbed back into the earth environment within 180 days.

50% of all household waste is compostable (food waste) and could be rotting away in a home backyard compost.
