Technodiversity Glossary

One single machine cuts and  chips whole trees in one single passage. This system is applied to SRC plantations and the most popular units are based on powerful (≥300 Kw) foragers

Functiogram: 

• Harvesting is simple: one single pass
• High productivity 20-35 t/h
• The base unit can be used for other tasks than SRC harvesting

• Chips are wet and cannot be dried without an energy input (active drying) or losses (passive drying)
• Requires flat terrain, solid
• Requires that the crop is in orderly rows
• Rather inflexible for stem size

• Industrial SRC in ex-arable land

Economic suitability

Example:

• machine costs without personal costs: 250,00 Euro/h
• personal costs per person: 35,00 Euro/h
• number of persons: 2
• in total: 320,00 Euro/h
• regression line time per tree
  • b₀ = 0,2
  • b₁ (tree volume) = 1,0
  • b₂ (skidding distance) = 0,01
