Abstract

The Timtek process involves crushing of small diameter trees to form mats which are coated with adhesive then pressed into boards. Crushing yields an effluent water that has a high biological oxygen demand (BOD), chemical oxygen demand (COD), and total suspended solids (TSS). This water must be remediated before it can be discharged into water ways. The objective of this study is to evaluate: 1) the co-composting potential for process waste water, scrim wood waste and poultry manure; and 2) the potential for phytoremediation of diluted process water using duckweed. The results showed that co-composting reduced the bulk and toxicity of both process waste water and wood waste. Plant growth studies showed the composted material is suitable for use as a soil amendment. The results of the phytoremediation study showed that the BOD of the water could be reduced, but levels were still too high for discharge in public waterways.
