1 . A city in Netherlands is planning to construct a pretty bike path made of recycled wood.
The first of its kind in the world, the path near the city of Emmen will be surfaced not with the usual asphalt（沥青） but with wood chips packed together with organic resin(有机树脂).
The idea behind the path is to cut the use of conventional, less eco-friendly materials such as concrete, which is very difficult to recycle.And the creation of the wood chips will require no direct cutting down of trees; the company leading the experiment, Grontmij, plans to use waste products from sawmills(锯木厂).
The idea of creating a permanent road from a material that is celebrated for its biodegradability(生物降解性)might seem ridiculous. But the engineers working on the path insist that the wood and resin surfacing will stay in good condition for a long time, with a working life at least as long as concrete or asphalt. Rudi van Hedel, project manager of bio-based economy at Grontmij, explained that the light weight of the material also makes it far easier to move.
However, van Hedal said, “At present, the material costs of the path are higher than those of traditional paths made of asphalt or concrete, but the construction costs are comparable or perhaps slightly cheaper. We expect that as production ability increases, the costs will go down. In the future, we hope to use bio-fibres(生物纤维)that are cheaper than the wood fibres we’re currently experimenting with, and we expect that biodegradable materials will be able to compete with asphalt and concrete.”
