Extends fresh produce shelf life, biodegradable in 6 weeks

Plastic packing made from crustaceans

There are few companies that still don’t recognise the importance of the issue of packaging waste. However, their choices are still largely dictated by cost and profitability. New and more sustainable alternatives to standard plastic packaging are coming onto the market daily, but they tend to carry hefty price tags.

A recent launch is Carapac, a biodegradable plastic made from crustaceans. Carapac has a number of advantages over conventional plastics. It is manufactured from waste from food processing plants and therefore does not require resources from the environment. It also has natural anti-fungal properties that make it ideal for packaging fruit and vegetables – extending their shelf-life by seven days in comparison with existing single-use plastics. The packaging can be disposed of by throwing it in the garden, where it biodegrades within six weeks, with the added benefit that it acts as a slow release nitrogen fertilizer in the soil.

But this comes at a price: Carapac is three times as expensive as standard plastic, and although this is considerably cheaper than some biodegradable packaging (which can cost up to five times the price of traditional plastic), it could prove a barrier to uptake.

However, as environmental campaigners – from the almost establishment Green Party through to the Extinction Rebellion guerrilla activists – testify, the environment has reached a tipping point, and we can no longer afford to use the conventional measure of cost as the determinant of our futures: this has the potential to cost us the earth.

The cost of transporting and disposing of waste (including recycling costs) need to become a key part of the equation.
