Possible Uses of Sawdust

Forests in developing countries are an important natural resource: they provide wood for fuel and for building material. A by-product of wood processing is sawdust, generally it is considered fairly useless and is therefore dumped in the direct surroundings of sawmills and burned, huge piles of smoldering sawdust are the result.

An Overwiew of Possible Uses of Sawdust describes a number of possible applications of sawdust. For instance as a fuel, in chemical industries, as a building material and in agriculture. It also covers some miscellaneous uses of this easy to recycle material.

Furthermore this survey examine! the feasibility of the application o the techniques mentioned in developing countries and gives recommendations in order to use sawdust as profitable as possible.

Old Sawmills

Of the water-powered sawmill! constructed in Europe in the last century, with mechanical part! which were mainly made of wood only a few are left. Most of then were gradually modernized, or were sacrificed for the sake of road-building or stream-regulating projects, o they were abandoned because o their low profitability and finally be came derelict. This process is advancing rapidly, and within the next few decades- apart from a few individual examples in open-air museums - these sawmills will hay, disappeared completely.

In contrast to the old grainmills, of which there are only two basic types, there is a wealth of different, and technically highly interesting designs among the old sawmills. For example, there are saws that have a water lever with a vessel which fills periodically instead of a water wheel. and there are large saws with water, wheels only SO to 65 cm in diameter.

Crank saw. Drawing taken from the book "Old Sawmills in the Black Forest and the Alpine Countries".

Herbert Juttemann's book, based in a study of some 100 old sawmills between 1965 and 19131, records many other remarkable design features and novel ideas. Even so, it is y no means purely a study of technological history; also, taking the 31ack Forest (FRO) as an example, it lescribes the economic and socio-historical milieu, including forestry and timber transport, especially with regard to rafts, the ownership of the sawmills, and the development of the timber business.

The designs of the sawmills and the way they worked are illustrated in clear, detailed drawings. The book is thus the first fundamental explanation and documentation of the individual types of sawmill.

Third World Tourism

At present tourism is the third most important industry in the global economy, after the energy and automotive industries. By the year 2000, according to reliable calculations, tourism will be the world's most important industry. Although world travel is increasing year by year, the Third World countries have only a small share of it. But in these countries especially, the effects of tourism are considerable. In particular, tourism in the Third World is resulting in changes in values and thus causing irreparable damage.

Third World Tourism - Development Strategy and Relationships is a critical examination of the phenomenon of worldwide mass tourism. The book runs to almost 300 pages. The author points out the structures of the tourist movement, its driving forces, its illusions, and also the way the image of foreign countries has changed. Tourism and development and tourism as cultural extermination are further topics dealt with in this study.

With its detailed appendix of bibliographies this is a book which demands much of the reader. Even though there are plenty of examples to illustrate the author's concerns, it is nevertheless no easy read. Some knowledge of sociological and ethnological terminology is needed. It is not a book that can and should be read at one sitting. The individual chapters are self-contained, and so it is more the kind of book you will want to dip into time and again. But it is certainly a worthwhile read for anyone interested in tourism and the Third World.
