NSFP – WASTE TO ENERGY PLANT

CONCEPT

Recycling Technologies Group Pty Ltd (RTG) have been asked to evaluate the potential waste stream
from the Neville Smith Forest Products Southwood sawmill and propose some ideas for a biomass
waste to energy plant and utilisation of the waste resource.

In this desktop study, we have only considered the biomass available from the Southwood Sawmill
operations.

Project Assumptions

We have made the following assumptions in our analysis:
ASSUMPTIONS TONNAGE
Wood waste volumes T / p.a. T / day T /
hr
Wood chip (green) 14000 56.0 7.0
Sawdust (green) 5000 20.0 2.5

Total Dry Material Volume – post drying
Wood Chip (dry) 8680 34.72 4.34
Sawdust (dry) 3100 12.4 1.55
Total raw material 11780 46.12 5.89

5.89
Operation Assumptions
Working days / year 250
Working hours / day - sawmill 8
Moisture Content of Wood chip and sawdust (%) 50
Moisture Content of Wood chip and sawdust post drying (%) 12

Gasifier will use 0.75kg pellets / k/w
• 1kg of water evaporated required 0.9kW Th energy
• Hours of operation for gasifier 7000
• Hours of operation for the drier 7000
