Production of light mouldings from lignocellulose-containing plant material

摘要

Using the process according to the invention, light mouldings of straw can be produced with substantially higher strength values without pollution of the environment, it being possible for the moulding to be composted or burned without pollution. Straw is pretreated with dilute caustic soda solution and then partially defibrated under control in a single working step and filtered off with suction in hollow moulds without application of pressure. The finished products can be used, inter alia, as spacers in the packaging industry, as bases to be fitted up in wreath-making installations and for three-dimensional mouldings, for example chair seats and chair backs, in the furniture industry.
