RENEWABLE ENERGY IN INDUSTRIAL APPLICATIONS<br />

fibers, but whole logs are usually used for<br />

veneers, such as plywood. It is also possible to<br />

m<strong>an</strong>ufacture similar eng<strong>in</strong>eered cellulosic<br />

products from other lign<strong>in</strong>-conta<strong>in</strong><strong>in</strong>g materials<br />

such as bamboo, straw, or sugar c<strong>an</strong>e residue.<br />

Eng<strong>in</strong>eered wood products are beneficial from <strong>an</strong><br />

energy <strong>an</strong>d CO2 perspective because:<br />

• They c<strong>an</strong> be made from fast grow<strong>in</strong>g crops or<br />

residues;<br />

• Their properties are superior to those of<br />

natural wood;<br />

• They open up new markets where wood could<br />

not compete;<br />

• They reduce the dem<strong>an</strong>d for tropical<br />

hardwoods.<br />

The st<strong>an</strong>d<strong>in</strong>g wood stock is about 422 Gt<br />

worldwide. The total global production of woodbased<br />

p<strong>an</strong>els, <strong>in</strong>clud<strong>in</strong>g plywood, particle board,<br />

fibre board <strong>an</strong>d oriented str<strong>an</strong>d board, reached<br />

266 million m 3 <strong>in</strong> 2007, about 175 Mt).<br />

Production of saw logs <strong>an</strong>d veneer logs<br />

amounted to1 007 million m 3 <strong>in</strong> the same year,<br />

<strong>an</strong>d of <strong>in</strong>dustrial roundwood to around 1 705<br />

million m 3 . This is around half of the total<br />

roundwood production of 3 591 million m 3 <strong>in</strong> the<br />

same year, the other half of which was used <strong>in</strong><br />

energy production.<br />

Eng<strong>in</strong>eered wood products accounted for only<br />

600 000 m 3 <strong>in</strong> 2007, about 0.3 Mt. Eng<strong>in</strong>eered<br />

wood product markets are very small today<br />

compared to conventional wood markets.<br />

New products such as pressed bamboo c<strong>an</strong><br />

achieve considerable strengths, comparable to<br />

that of tropical hardwoods. This market is<br />

is of the order of 100 Mt per year. Ch<strong>in</strong>a is by far<br />

the largest producer, produc<strong>in</strong>g 60 Mt 80 Mt/yr),<br />

followed by India. Bamboo production is rapidly<br />
