Injection-molding wood powder for sustainable fabrication

Biomass materials such as wood are environmentally-friendly alternatives to fossil resources. As an example, wood is typically non-toxic and carbon neutral. Furthermore, wood can be produced in a sustainable manner by appropriate ...

Save the bees (and time and money) by creating a bee lawn

Flowering "bee lawns" that attract pollinators are a compromise between fastidious turf management and the more casual yard approach. They add biodiversity to the landscape and need less maintenance. That makes them cost-effective, ...

New model predicts changes in wood

Wood is a living material that changes with varying temperatures and humidity. Sabina Huč, a former researcher at the University of Borås, has developed a model that can predict wood's behavior. It has already been used ...

Wood consumption in energy generation continues to increase

In 2018, the consumption of wood fuels reached yet another record as a result of the increased use of black liquor produced by the forest industries. Heating and power plants consumed the same amount of solid wood fuels as ...

Using 60% less water in paper production

An EPFL researcher has developed a mathematical model for optimizing heat transfer in factories and dramatically reducing water and energy consumption. The model could, in theory, cut water use by 60 percent at a Canadian ...

Bacteria uses viral weapon against other bacteria

Bacterial cells use both a virus—traditionally thought to be an enemy—and a prehistoric viral protein to kill other bacteria that competes with it for food according to an international team of researchers who believe ...

Wood

Wood is an organic material; in the strict sense it is produced as secondary xylem in the stems of trees (and other woody plants). In a living tree it conducts water and nutrients to the leaves and other growing tissues, and has a support function, enabling woody plants to reach large sizes or to stand up for themselves. However, wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or wood chips or fiber.

People have used wood for millennia for many purposes, primarily as a fuel or as a construction material for making houses, tools, weapons, furniture, packaging, artworks, and paper. Wood can be dated by carbon dating and in some species by dendrochronology to make inferences about when a wooden object was created. The year-to-year variation in tree-ring widths and isotopic abundances gives clues to the prevailing climate at that time.
