IN AN INDUSTRY WITH A LINGO OF ITS OWN

I'M WELL-DEFINED

PHOTO-DEGRADABLE / PHOTO-DEGRADATION

Photodegradation is the alteration of materials by light. Our ØPACKS Range made of stone paper is photo-degradable meaning that, with exposure to light, in 12-18 months they will decompose, leaving behind only CaCO3 (calcium carbonate / limestone), a substance commonly found in nature.

HOME COMPOSTABLE / COMPOSTING

As more and more people become conscious of the waste generated by their own household and desire to reduce how much they send to landfill, home composting is increasing.

Home composting is ideal for fruit and veg scraps, leaves, sticks, twigs and newspapers, lawn clippings, egg shells, coffee grounds, tea leaves etc.

Packaging materials can be certified ‘Home Compostable’ if they conform to the Australian Standard AS 5810-2010.

Our comPOST Range has this certification.

Certified Compostable materials must meet the following four criteria:

  1. Biodegradability – Determined by measuring the amount of CO2 produced over a certain time period by the biodegrading plastic.
  2. Disintegration – Measured by sieving the material to determine the biodegraded size and that less than 10% remains on a 2mm screen within a certain number of days.
  3. Eco-Toxicity – Measured by testing the concentrations of heavy metals to ensure that they are below the limits set by the standards and by testing plant growth by mixing the compost with soil in different concentrations and comparing plant growth in test and controlled compost samples.
  4. Worm-Toxicity 

COMMERCIALLY 'HOT' COMPOSTABLE / COMPOSTING

Commercial or industrial composting is large-scale composting which is designed to handle a very high volume of organic waste, as opposed to private or home composting, which handles organic waste from one household or facility.

Some materials will decompose under certain conditions which can only be achieved in commercial composting facilities, the key condition being the temperature reached in the compost.

Our comPOST Packs are commercially compostable.

The composting industry is slowly developing across most regions in Australia and New Zealand to be able to process compostable packaging, however not all of these facilities can process compostable packaging.

BIO-DEGRADABLE / BIO-DEGRADATION

Bio-degradation is the disintegration of materials by bacteria, fungi, or other biological means. If a material is bio-degradable (sometimes written biodegradable), it is able to be broken down by bio-degradation.

Bio-degradable plastics can be either made from bio-plastics or from traditional petrochemicals engineered to break down more quickly than normal plastics. Caution needs to be exercised with these plastics as they may break down into microplastic particles and the additives required to accelerate the degradation process can be toxic to the environment.

It is important to note that unlike compostable products – there is no requirement for products labelled `biodegradable’ to meet any eco-toxicity or break-down timeframe requirements.

OXO-DEGRADABLE / OXO-DEGRADATION

Oxo-degradable means a material will break down with exposure to oxygen. Oxo-degradable plastics are being produced and sold in many countries, with society being led to believe they safely bio-degrade in nature. Yet significant research suggests that oxo-degradable plastics do not safely biodegrade but fragment into small pieces, contributing to microplastics pollution. “The available evidence overwhelmingly suggests oxo-degradable plastics do not achieve what their producers claim and instead contribute to microplastic pollution. In addition, these materials are not suited for effective long-term reuse, recycling at scale or composting, meaning they cannot be part of a circular economy.” – Rob Opsomer, Lead for Systemic Initiatives at the Ellen MacArthur Foundation

Some of the (totally misleading) brand names given to oxo-degradable bags and other products are BioWrap for magazines, EP Tech “biodegradable” bags and bin liners … you know, the ones with the green frog on them.
