Compostable, Bio-based Bag Fits Wonky Bread’s Eco-Friendly Ethos

D2C company Earth & Wheat switches from a fossil-based bag to a compostable one made from renewable resources to ship its mixed bakery bread varieties that have been rescued from becoming waste.

The C-Bag is certified by TUV as OK Home Compostable. This certification was developed to guarantee complete biodegradability in garden compost heaps and other slower-paced processes.

Chiefly a British slang term, β€œwonky” is used to describe something that is crooked, off-center, or askew. Thus, U.K.-based direct-to-consumer company Earth & Wheat chose the moniker β€œwonky bread boxes” for its products, which consist of cases of mixed varieties of fresh bakery bread, among them products as varied as pita, rolls, pancakes, buns, and wraps, as well as many others that would otherwise have been wasted due to appearance standards or overproduction.

Earth & Wheat was launched in 2021 to address food waste, and in particular, bread. According to the company, in the U.K. alone, 24 million pieces of bread are wasted each day. Earth & Wheat’s wonky bread boxes, which are said to be the first and only such products in the country, are available to D2C customers throughout England, Wales, the Isle of Wight, and Scotland (with some exceptions) on a subscription basis. The company works directly with bakeries, rescuing bread immediately after baking that would otherwise have gone to waste. It then ships its customers 2-kg boxes of the fresh, but wonky, bread directly from the bakery overnight, donating a meal to charity for every box sold.

The sustainability stats for the rescued bread program are impressive: Every box saves 3,240 liters of fresh water and 3,053 grams of CO2 from going to waste. Until recently, however, the company felt its packaging was not optimal from an envioronmental standpoint. While its wonky bread box is made from recyclable corrugated, the primary packaging consisted of a plastic bagβ€”a format that was incompatible with the brand’s values.

To address the disconnect, Earth & Wheat switched to a home-compostable, bio-based bag, the C-Bag from KM Packaging, as the primary package for its bread. The C-Bag was developed by KM in partnership with Treetop Biopak and is made from renewable resources such as cornstarch and other biopolymers. The film is said to have similar properties to petroleum-based plastic, including impact, puncture, and water resistance, and provides a comparable look and feel.
