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 />

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 />
