BASF introduces industrially compostable twine for greenhouse crop production

BASF has expanded its ecovio® biopolymer line to include a new grade, T 2206, certified industrially compostable per EN13432. This material can be used to manufacture black twines for supporting climbing fruits and vegetables like tomatoes and cucumbers in commercial greenhouse operations.

BASF T 2206 biodegradable twine

Supporting circular agricultural practices

After the growing cycle, the twines made from ecovio T 2206 can be collected along with the plant residues and sent to an industrial composting facility, where they will biodegrade. This end-of-life solution avoids the release of microplastics that would occur with conventional plastic twines. Instead, the nutrient-rich biomass can be recycled into valuable compost, supporting circular agricultural practices.

Trials demonstrate ecovio T 2206 twines perform excellently throughout crop growth in greenhouses across diverse climates. For growers, the compostable twines eliminate the labour of separating them from plant matter post-harvest. Manufacturers benefit from being able to produce these twines on standard polypropylene equipment.

Agricultural mulch films

In addition to the T 2206 twine grade, BASF offers ecovio M 2351, a soil-biodegradable material per EN 17033 designed for agricultural mulch films. These films fully degrade in soil from microbial action, avoiding microplastic accumulation. They provide benefits like higher yields, reduced water/herbicide needs, and easier removal compared to polyethylene mulch films.

The ecovio line, a blend of BASF’s PBAT ecoflex® and renewable materials, is certified compostable per EN13432 standards. Studies show ecovio reduces food waste, returns nutrients via compost, and prevents microplastics in soil – furthering a circular bioeconomy through organic recycling channels for products like bags, films, and foodservice items.
