Tung oil has been used for hundreds of years in China, where it was used as a preservative for wood ships. The oil penetrates the wood, and then hardens to form an impermeable hydrophobic layer up to 5 mm into the wood. As a preservative it is effective for exterior work above and below ground, but the thin layer makes it less useful in practice.
Fiberboard manufacture begins with wood chipping: fresh or recycled wood material is cut and sorted to small pieces of similar size. Chips are washed to remove things such as dirt and sand. Metal scraps such as nails can be removed with a magnet placed over a conveyor belt on which the chips move forward.
Hardboard is similar to particle board and medium-density fiberboard, but is denser, stronger and harder because it is made out of exploded wood fibers that have been highly compressed. [ 3 ] The density of hardboard is higher than 500 kg/m 3 (31 lb/cu ft), [ 4 ] usually about 800–1,040 kg/m 3 (50–65 lb/cu ft). [ 5 ]
Oil plunged more than 6%. their biggest daily drop in more than two years after an expected Israeli retaliatory strike against Iran over the weekend spared the country’s petroleum infrastructure.

Per the New Hampshire Office of Energy and Planning release on Fuel Prices updated on 5 Oct 2015, the cost of #2 fuel oil delivered can be compared to the cost of Bulk Delivered Wood Fuel Pellets using their BTU equivalent: 1 ton pellets = 118.97 gallon of #2 Fuel Oil. This assumes that one ton of pellets produces 16,500,000 BTU and one gallon ...
