Progress 10/01/97 to 09/30/98
Outputs
The environmental group of the Institute of Wood Research at Michigan Tech University has been developing economical and efficient methods for remediation of air, water and soil. Currently, most of the activity has concentrated on the development of biofilters for removing volatile organic compounds from air. Laboratory studies have been completed on this technology and have been reported at several national and international conferences. Pilot facilities of this technology has been set up at several hardboard and OSB plants to scale up the technology. Initial results have been very promising. A second approach has been the use of chemical additives that are blended with the air to destroy air emissions . Ten different chemical treatments have been evaluated and six have been found to be effective.. Future efforts will be directed to understanding the biology and chemistry of the chemical treatment system, and to optimize the system for destruction of organic
compounds.

Progress 10/01/96 to 09/30/97
Outputs
The environmental group of the Institute of Wood Research at Michigan Tech University has been developing economical and efficient methods for remediation of air, water and soil. Currently, most of the activity has concentrated on the development of biofilters for removing volatile organic compounds. At this time, ten pilot-scale biofilters are in operation using bark, wood chips and celite as the biofilter media. Destruction efficiencies for methanol are averaging one hundred percent and for alpha-pinene are forty to sixty percent. Work has been started with two industrial companies to improve the operation of their commercial biofilters. Future efforts will be directed to understanding the biology and chemistry of the biofiltration system, and to optimize the system for destruction of organic compounds.

Progress 10/01/95 to 09/30/96
Outputs
The environmental group of the Institute of Wood Research at Michigan Technological University has been developing economical and efficient methods for remediation of air, water and soil. Currently, most of the activity has concentrated on the development of biofilters for removing volatile organic compounds. At this time, four pilot-scale biofilters are in operation using wood chips and celite as the biofilter media. Destruction efficiencies for methanol are averaging one hundred percent and for alpha-pinene are forty to sixty percent. Most of the current and future efforts will be directed to understanding the biology and chemistry of the biofiltration system, and to optimize the system for destruction of organic compounds.

Progress 10/01/94 to 09/30/95
Outputs
The environmental group of the Institute of Wood Research has been developing economical and efficient methods to remediate sites contaminated with organic and inorganic chemicals from the wood industry petroleum and chemical industry. Over the past year we have been working in the following areas: Isolation and characterization of microorganism systems for volatile organic compounds to use in biofiltration systems; Development of more effective biofiltration systems using biologically active support media (wood, bark and compost); Combinations of biofiltration systems with other biological and chemical systems to enhance overall treatment of volatile organic compounds; Continued work at sites in British Columbia and Minneapolis, MN to clean up soils and groundwater; Develop a program to assist small to medium forest-based companies on environmental problems.
