Occupational exposure to solid chemical agents in biomass

Maintenance and ash removal workers were exposed to high inhalable dust concentrations inside biomass-fired boilers. The median air inhalable dust concentration in workers' breathing zones were 33 mg m (-3) and 120 mg m (-3) in ash removal and maintenance tasks, respectively. The median concentration of manganese (0.31 mg m (-3)) exceeded the occupational exposure limit in worker's …

Production of methanol from biomass

If a biomass price of 1.7 US$/GJ could be realised (a realistic price for e.g. Brazil), methanol production costs would become 8.0 – 11 US$/GJ for 400 MWth concepts. On the other hand, when biomass costs increase to 3 US$/GJ (short term Western Europe) the production cost of methanol will increase to 10 – …
