1. Off-gassing from thermally treated lignocellulosic biomass
Abstract : Off-gassing of hazardous compounds is, together with self-heating and dust explosions, the main safety hazards within large-scale biomass storage and handling. Formation of CO, CO2, and VOCs with concurrent O2 depletion can occur to hazardous levels in enclosed stored forest products. READ MORE

2. Mitigating Off-Gassing and Self-Heating in Fuel Wood Pellets Storage : A Raw Materials Selection and Pre-Treatment Centred Approach
Abstract : Wood pellets have become a preferred solid biomass fuel for heat and power generation due to their standardized nature, known properties, and consistent quality. However, pellets produced from fresh sawdust sometimes undergo self-heating and off-gassing during storage. This poses a challenge for their transportation and storage. READ MORE

3. Understanding the Influence of Wood Extractives on Off-Gassing during Storage of Wood Pellets
Abstract : Wood pellets have become a solid biomass fuel of choice because they are a standardized product with known quality properties. However, the self-heating and off-gassing tendencies during storage of wood pellets threatens the consistency of the pellets’ quality properties. READ MORE

4. Effects of high sugar concentrations in production scale bioreactor : a scale-down study of s. cervisiae
Abstract : Substrate concentration gradients exist in large-scalebioreactors, due to a combination of insufficient mass transferand mixing, and microbial activities. Zones with high substrateconcentration may arise close to a feed point. It is largelyunknown to what extent these gradients influence themicroorganisms and what the microbial response might be.

5. Influence of building envelope on indoor air quality: Field measurements, analysis, and method development related to indoor odors
Abstract : The ventilation system should provide occupants with fresh air while removing excess pollutants from the building. However, increasing ventilation may inadvertently draw more pollutants into the occupant area or prove ineffective in altering emission rates from building materials and furnishings. READ MORE
