Wood-free paper is paper created exclusively from chemical pulp rather than mechanical pulp. [1] Chemical pulp is normally made from pulpwood, but is not considered wood as most of the lignin is removed and separated from the cellulose fibers during processing, whereas mechanical pulp retains most of its wood components and can therefore still be described as wood.
As wood glue, PVAc is known as "white glue" and the yellow as "carpenter's glue". As paper adhesive during paper packaging conversion. In bookbinding and book arts, due to its flexible strong bond and non- acidic nature (unlike many other polymers).
The commonly known fungal species, white-rot basidiomycetes, are capable of degrading polymeric carbohydrates and using them for growth. Pleurotus ostreatus is an edible white-rot fungus known to degrade cellulose , hemicellulose and lignin , hence reinforcing its potential to thrive on wastes such as wood, textile, and agricultural residues.
Human composting takes surprisingly little to complete. A body is wrapped in a biodegradable shroud and placed in a long metal capsule — surrounded with a mixture of wood chips, mulch and ...

A plant proteins-based biodegradable packaging alternative to plastic was developed based on research about spider silk which is known for its high strength and similar on the molecular level. [32] [33] Researchers at the Agricultural Research Service are looking into using dairy-based films as an alternative to petroleum-based packaging.
The process of manufacturing blackout was invented by Baltimore-based Rockland Industries, [2] and involves coating a fabric with layers of foam, or 'passes'. A '2-pass' blackout is produced by applying two passes of foam to a fabric – first, a black layer is applied to the fabric, then a white or light-colored layer is applied on top of the black.
