The aim of the subproject is the application of the biomass cascading principles in the domestic wood and paper industry. This concept is a sequential utilization of biomass as well as a more complete life cycle utilization of related products. That is to say that the harvested wood must not be burned immediately. It is required to preserve the bounded carbon  in the wood products as CO2 as long as possible and to allow its emission back to the atmosphere only in the last case (even than with energy winning) from which the trees and the sea can absorb it again.

1. Statement of waste management: International and domestic waste management situation were estimated and considered by respect of wood according to literature surveys and interviews. In this context, we learned the topic of domestic and EU regulatory environment (for example: Kyoto Agreement, White Book, 2001/77/EK directive, 2003/30/EK, EWC, 17. BImSchV, 2000. XLIII. act etc.) and according to the assessment of companies we learned the types of waste, creation sites etc (FALCO, Swedwood Ltd).

2. Utilization in the wood board industry: According to the international experience and the types of waste generated in our country, the wood byproducts and residual wood parts are used in the board industry, the recycled and waste paper products in the packaging paper production, thus opting for a new cycle of the biomass cascade. In this context, we began the assessment, categorization and draw the characteristic features of wood and paper wastes derived primarily from Falco and Kronospan Ltd.-MOFA Hungary Ltd area, taking into account the currently operating waste handling yards, where wood waste is treated separately, for example at the STKH Ltd. in Sopron.

3. Liquefied wood as an adhesive: In this subtask, several important goal will be achieved. This is an opportunity to preserve wood and paper wastes and by-products in products, moreover the adhesive is completely environmentally friendly, formaldehyde-free. The first phase of the research the relevant literature was revealed and based on that a new development direction was determined. Initial protocols were developed and the procurement of the necessary raw materials was started (PEG, antrachinon, sulfuric acid, fiber, etc.).
