The recyclable material can be made water- and fire-resistant. It provides sufficient strength for use as a building material. [70] Cellulose insulation made from recycled paper is becoming popular as an environmentally preferable material for building insulation. It can be treated with boric acid as a fire retardant.

Cellulose is a polymer made of repeating glucose molecules attached end to end. [4] A cellulose molecule may be from several hundred to over 10,000 glucose units long. Cellulose is similar in form to complex carbohydrates like starch and glycogen. These polysaccharides are also made from multiple subunits of glucose.
The biomass is primarily composed of carbohydrate polymers cellulose, hemicellulose, and an aromatic polymer (lignin). The hemicellulose is a polymer of mainly five-carbon sugars C 5 H 10 O 5 . [2] and the cellulose is a polymer of six-carbon sugar C 6 H 12 O 6 . [3]
Carboxymethyl cellulose (CMC) or cellulose gum [1] is a cellulose derivative with carboxymethyl groups (-CH 2-COOH) bound to some of the hydroxyl groups of the glucopyranose monomers that make up the cellulose backbone. It is often used in its sodium salt form, sodium carboxymethyl cellulose. It used to be marketed under the name Tylose, a ...
A slab of pykrete Pykrete is made of 14% sawdust and 86% water by mass.. Pykrete (/ ˈ p aɪ k r iː t /, PIE-creet) [1] is a frozen ice composite, [2] originally made of approximately 14% sawdust or some other form of wood pulp (such as paper) and 86% ice by weight (6 to 1 by weight).
Cellophane is a thin, transparent sheet made of regenerated cellulose. Its low permeability to air, oils, greases, bacteria, and liquid water makes it useful for food packaging. Cellophane is highly permeable to water vapour, but may be coated with nitrocellulose lacquer to prevent this.
Made from all-natural cellulose, these compressed options fatten up when immersed in water. Keep them fresh in between use by running them through the dishwasher. $20 at Williams Sonoma
A wet microbial cellulose pellicle being removed from a culture Nata de coco, a traditional food product from the Philippines made from fermenting coconut water with Komagataeibacter xylinus. Bacterial cellulose is an organic compound with the formula (C 6 H 10 O 5) n produced by certain types of bacteria.
