A modern economy must take into consideration a rational administration of wastes. Although the wooden industry is not such a pollute industry, the waste resulted as lumber from the processes has an unfavourable impact on the environment. This paper presents two possible methods to a superior re-evaluation of the wood waste. In this way new values are created parallel to the decrease of the negative phenomena caused by depositing of these wastes.

This study is to select from the multitudes of the possibilities of obtaining and using wastes and it restrains its area to the using of wastes in order to obtain porous ceramics used to the fertilization of soil and the nutrition of the plants (the fertilizers appear as granules, pellets or pipes). The fertilizers contain elements and microelements needed in the growth of plants.
