NOVEL CLOSED-LOOP TECHNOLOGY FOR PANEL RECYCLING

Objective



In Europe, about 30 million m3 of particleboard and nearly 3.5 million m3 of medium
density fibreboard (MDF) were produced in 1995, half of the world's production.
The amounts of refused board are already significant and their handling causes
problems in many European countries. It should be noted that burning old furniture,
apart from wasting natural resources, is not environmentally desirable mainly due
to the creation of dioxins, carbon dioxine, etc. Moreover, Germany has already
enacted environmental legislation that forbids the dumping of materials containing
more than 5 % organic compounds by the year 2005 (TA - Siedlungsabfall).
Similar legislation may be enacted in other European countries.

This project addresses this already existing and progressively gaining more
importance problem. According to the proposed recycling process, particleboard
and medium density fibreboard will be pulped using conventional pulping
techniques. The fibrous material generated will be used as a starting material for
the production of medium density fibreboard and/or lower paper grades. The black
liquor containing the degradation products of the resin will be used as an extender
for conventional amino and phenolic resins. Preliminary experiments have proved
this concept and a patent (DE-PS-4334422) was recently granted in Germany.

The objective of the project is to develop a process for the production of medium
density fibreboard and lower grade paper or paperboard with acceptable properties
by using exclusively fibres produced by pulping waste panels. Furthermore, the
black liquor generated by the pulping process will be used to substitute up to a
level of 30 % synthetic resins such as amino and phenolic resins used in the
production of wood-based panels. Another objective is further recycling of the
panels produced by this process.

On successful completion of the project a novel closed-loop technology for the
recycling of old furniture and other wood-based panels will be available to address
the sizeable demand for recycling expected due to forthcoming legislation. The
technique of this projects is unique as it involves the recycling of both the
lignocellulosic part of particleboards and fibreboards and of the binder resin as well,
using an environmentally friendly process.

The partners form a powerful consortium of a university with innovative science
needing implementation, an SME skilled in introducing new technology into the
board industry, an industrially friendly funded research institute with specialised
expertise in wood research and three industrial companies; an adhesives
manufacturer, a producer of wood panels and paperboard. With this industrial
involvement and the commitment to finding a solution to a problem critical for our
environment, there is a very good prospect of the new technology being exploited
in the medium term.
