The longevity and usefulness of stone can be extended by sealing its surface effectively, so as to exclude harmful liquids and gases. The ancient Romans often used olive oil to seal their stone. Such treatment provides some protection by excluding water and other weathering agents, but it stains the stone permanently.
Engineered stone is a composite material made of crushed stone bound together by an adhesive to create a solid surface. The adhesive is most commonly polymer resin, with some newer versions using cement mix. This category includes engineered quartz (SiO 2), polymer concrete and engineered marble stone. [1]
Bretonstone, also known as vibro-compression under vacuum, is a formerly-patented technology [2] [3] invented in the early-1970s [citation needed] by Breton S.p.A. [4]Nowadays most manufacturers of engineered stone use similar technology, typically involving quartz and a resin binder combined under vacuum, and compressed under heat into a desired form such as a countertop slab.
The material isn't inherently dangerous when it's left alone but consumers shouldn't let workers cut, grind or polish the engineered stone inside their home, said Bob Blink, past president of the ...
Phytoremediation technologies use living plants to clean up soil, air and water contaminated with hazardous contaminants. [1] It is defined as "the use of green plants and the associated microorganisms, along with proper soil amendments and agronomic techniques to either contain, remove or render toxic environmental contaminants harmless".

The Construction, Forestry, Maritime, Mining and Energy Union, the major workplace trade union representing construction workers in Australia, has called for a nationwide ban on high-silicon engineered stone by 2024, and stated that it will ban its members from using the material if a governmental ban is not put in place.
Live stakes are hardwood cuttings with the branches removed that, when planted in moist soil, will grow new plants from the stems of the cut branches. They can be used alone, implanted into 2-inch (5 cm) pilot holes in the soil, or used as a device to secure other bioengineering materials such as rolled erosion control products and coir logs.
