Abstract
A biodegradable board having a high stiffness to weight ratio includes cocoa shell particles, cellulosic wood-based fibers, and no added binders. The cocoa shell particles may be sourced from a cocoa processing waste stream. The board has a grammage of at least about 2000 g/m2. The board may be assembled into a self-supporting point-of-sale display unit for displaying food products.
Claims19
A biodegradable board comprising:
- from about 35% to about 50% cocoa shell particles;
- cellulosic wood-based fibers;
- and
- no added binders,
- wherein the biodegradable board is formed of a single layer, and has a density from about 1000 kg/m3 to about 1100 kg/m3.
A method of making a biodegradable board, the method comprising:
- grinding cocoa shells sourced from a cocoa processing waste stream;
- providing pulp from cellulosic wood-based waste material;
- combining the ground cocoa shells with the pulp from cellulosic wood-based waste material to form a mixture;
- compressing the mixture under heat to form a biodegradable board,
- wherein the biodegradable board comprises from about 35% to about 50% cocoa shell particles, and
- the biodegradable board is formed of a single layer, and has a density from about 1000 kg/m3 to about 1100 kg/m3.
A self-supporting point-of-sale display unit comprising one or more biodegradable boards, each biodegradable board having a grammage of at least about 2000 g/m2 and comprising:
- from about 35% to about 50% cocoa shell particles;
- cellulosic wood-based fibers;
- and
- no added binders,
- wherein the biodegradable board is formed of a single layer, and has a density from about 1000 kg/m3 to about 1100 kg/m3.
