Biodegradable mesh bags from cellulose or biopolymers
Alternative to plastic mesh bags
Oyster restoration efforts all over the world use plastic mesh bags. The mesh bags are filled with oyster shells and placed into the water to recruit oysters. The plastic however, remains and pollutes the ecosystem. BESE-products offers two types of mesh bag, made from cellulose or biopolymers. Both bags are fully biodegradable.
After oysters have colonized the structure the bags will fall apart, leaving only oysters behind.
We have 2 types of cellulose mesh bags available (alternative size available > 2000 pc), made of cellulose from 100% (beech)wood of thinning EU forest:
- Mesh bags 70*28 cm
- Mesh bags 50*34 cm
The mesh size of the cellulose mesh is small: only 3 millimeters / 0,12 inches. The cellulose mesh is completely biodegradable and will last a couple of weeks to several months depending on the environmental conditions; they'll degrade slower in a colder and dryer environment. More information can be found in the product specification factsheet. Interested in product and shipping prices? Send us a message below.
From 2022 onwords we have a new and longer lasting mesh type available!
Since the cellulose mesh often degrades too fast for oyster reef restoration purposes, we designed a biopolymer mesh which is expected to last 3-10 years, depending on environmental conditions (UV, oxygen availability and temperature).
The biopolymer mesh is only avalaible on a sleeve (600 m), with a diameter of 30 cm and a mesh size of 1 cm. On request smaller amounts are available.
The biodegradable mesh can also function as a grow-out bag for aquatic vegetation like riverbank vegetation and submerged aquatic vegetation. Moreover, filled with sand, stones or other material the bags can function as wavebreakers in dynamic zones.
