Beschreibung
Zusammenfassung:	FIELD: technological processes. ^ SUBSTANCE: method includes grinding of woodworking wastes or plant materials, mixing with binder and subsequent pressing. Binder is liquid sodium glass that contains dry substance of glass 30-70; water 70-130 wt parts; at that cold pressing is executed, and binder is taken in amount of 20-50 wt parts per 100 wt parts of wastes. Binder may additionally contain hardener - salts of mineral acids in amount of 3-5 wt parts, in this case liquid sodium glass is preliminarily homogenised with hardener. ^ EFFECT: invention makes it possible to prepare ecologically clean, thermally resistant and moisture resistant items. ^ 8 cl, 3 tbl
