Sawdust in the context of "Wood fuel"

A composting toilet is a type of dry toilet that treats human waste by a biological process called composting. This process leads to the decomposition of organic matter and turns human waste into compost-like material. Composting is carried out by microorganisms (mainly bacteria and fungi) under controlled aerobic conditions. Most composting toilets use no water for flushing and are therefore called "dry toilets".

In many composting toilet designs, a carbon additive such as sawdust, coconut coir, or peat moss is added after each use. This practice creates air pockets in the human waste to promote aerobic decomposition. This also improves the carbon-to-nitrogen ratio and reduces potential odor. Most composting toilet systems rely on mesophilic composting. Longer retention time in the composting chamber also facilitates pathogen die-off. The end product can also be moved to a secondary system – usually another composting step – to allow more time for mesophilic composting to further reduce pathogens.

A silo (from Ancient Greek σιρός (sirós) 'pit for holding grain') is a structure for storing bulk materials.

Silos are commonly used for bulk storage of grain, coal, cement, carbon black, woodchips, food products and sawdust. Three types of silos are in widespread use today: tower silos, bunker silos, and bag silos.

A briquette (French: [bʁikɛt]; in English also spelled briquet) is a compressed block of coal dust or other combustible biomass material (e.g. charcoal, sawdust, wood chips, peat, or paper) used for fuel and kindling to start a fire. The term is a diminutive derived from the French word brique, meaning brick.

Linoleum is a floor covering made from materials such as solidified linseed oil (linoxyn), pine resin, ground cork dust, sawdust, and mineral fillers such as calcium carbonate, most commonly on a hessian or canvas backing. Pigments are often added to the materials to create the desired color finish. Due to the pigment being mixed directly into the linoleum cement, the finished color of the tile remains visible even after years of wear. In the past some of these pigments were iron oxide, red lead or lithopone.

It gained popularity as a beautiful and easy to clean flooring option in the late 19th century and is still used today. Commercially, the material has been largely replaced by sheet vinyl flooring, a plastic alternative made of polyvinyl-chloride, though many still call it linoleum. This is mainly due to the fact that its plastic counterpart is less costly and much faster to produce.

Swarf, also known as chips or by other process-specific names (such as turnings, filings, or shavings), are pieces of metal, wood, or plastic that are the debris or waste resulting from machining, woodworking, or similar subtractive (material-removing) manufacturing processes. Swarf can be small particles (such as the gritty swarf from grinding metal or the sawdust from sawing or sanding wood); long, stringy tendrils (such as the springy chips from turning tough metals, or long shavings from whittling); slag-like waste (such as is produced within pipe during pipefitting work); or stone fragments and dust (as in masonry).

Some of these terms are mass nouns (such as swarf and sawdust) and some of them are count nouns (such as chips, filings, or shavings).

Furfural is an organic compound with the formula C₄H₃OCHO. It is a colorless liquid, although commercial samples are often brown. It has an aldehyde group attached to the 2-position of furan. It is a product of the dehydration of sugars, as occurs in a variety of agricultural byproducts, including corncobs, oat, wheat bran, and sawdust. The name furfural comes from the Latin word furfur, meaning bran, referring to its usual source. Furfural is derived only from dried biomass. In addition to ethanol, acetic acid, and sugar, furfural is one of the oldest known organic chemicals available readily purified from natural precursors.
