Forest residue recovery

• Residue recovery costing tool -determines the delivered cost of forest residue for a complete recovery operation. Results given in $/GJ as well as $/tonne. view tool
• Landing residue recovery calculator - estimates the amount of in-forest residue left at a landing site after a harvesting operation. Calculation based on type of harvesting and log-making system and crop quality. view calculator
• Cutover residue recover calculator-estimates the amount of in-forest residue left on cutover after a harvesting operation. Calculation based on type of harvesting system and crop quality. view calculator
• Residue transport cost calculator-determines forest residue transportation costs via various transportation schemes and machines. Results given in $/GJ as well as $/tonne. view calculator
• Supply curve tool-interactive tool to generate supply curves for forest residues for a number of locations throughout New Zealand. These supply curves show the cost of residues vs. volume extracted. The tool allows user to input fuel costs and residue purchase price. view calculator

Miscellaneous

• CO2 emission calculator-calculates the tonnes of CO2 equivalent emited by buring different fossil fuels. view calculator
• Return on investment calculator-calculates the return on capital investment via number of criteria including simple payback time, NPV and IRR. view calculator
