Wood fibres can be used as a substrate in hydroponics. Wood wool (i.e. wood slivers) have been a substrate of choice since the earliest days of the hydroponics research. [4]
Excelsior, or wood wool. Wood wool, known primarily as excelsior in North America, is a product made of wood slivers cut from logs. It is mainly used in packaging, for cooling pads in home evaporative cooling systems known as swamp coolers, for erosion control mats, and as a raw material for the production of other products such as bonded wood wool boards.
Tree-free paper fibers, sourced from annual crops and agricultural residues, present an alternative to traditional wood pulp. These fibers typically require fewer chemicals and less energy to process. They also produce less waste. Tree-free papers can be combined with recycled materials to produce a variety of paper products.
Sustainable packaging is packaging materials and methods that result in improved sustainability. [2] This involves increased use of life cycle inventory (LCI) and life cycle assessment (LCA) [ 3 ] [ 4 ] to help guide the use of packaging which reduces the environmental impact and ecological footprint .
Pre-consumer waste is a material which left the paper mill but was discarded before it was ready for consumer use. Post-consumer waste is material discarded after consumer use, such as old corrugated containers (OCC), old magazines, and newspapers. [2] Paper suitable for recycling is called "scrap paper", often used to produce moulded pulp ...
An X often marks a hazard or tree to be removed. Circles and dots can mean trees to take, but sometimes they mean trees to leave. Numbers on trees are usually to tally them before a harvest.
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.
Bloated food packaging doesn’t always mean the food inside is dangerous to eat, says Zhang. If you live in a high-altitude area, such as Denver, a food package may swell because the air pressure ...
