BESE focuses on the effective restoration of degraded natural areas along the coast, such as salt marshes, mangroves and seagrass beds. These areas provide a living environment for many species of animals and plants. They also contribute to water purification, food production, CO2 sequestration and the protection of coastal areas.

Structures used in ecological restoration projects often consist of permanent materials such as concrete, metal or plastic. For example, plastics are often used in river banks to prevent erosion. These materials do not break down and can cause soil and water pollution. BESE has developed materials for habitat restoration that are biodegradable and slowly become part of the natural environment.

The flagship product of the company is BESE elements: biodegradable 3D sheets that have been highly successful in a variety of restoration projects. The BESE elements consist of biodegradable biopolymers of waste starch from the potato industry in the Netherlands. They have been designed by ecologists to mimic the properties of natural habitats specifically to promote the colonisation by plants and animals.
