<strong>International</strong> <strong>Review</strong> <strong>of</strong> <strong>Waste</strong> <strong>Policy</strong>: Annexes<br />

Critic Critical Critic al assumptions<br />

assumptions<br />

Inclusion <strong>of</strong> carbon sequestration; substantial avoided<br />

emissions from landfill / wood energy not used<br />

Incineration <strong>of</strong> paper; use <strong>of</strong> wood energy to produce<br />

virgin paper<br />

Recycling process uses similar / less carbon intensive<br />

energy generation process; relatively high energy use in<br />

virgin manufacturing process<br />

Recycling process uses a more carbon intensive energy<br />

generation process<br />

Best -15.1 Higher energy use in virgin manufacturing process<br />

Worst 1.5 High recovery efficiency from incinerator residues<br />

Typical Typical -9.17 9.17<br />

Best -4.1<br />

Typical Typical -1.4<br />

Best -2.5<br />

Recycled is substituted for virgin on 1:1 basis; no hot<br />

water washing required<br />

Compared to incineration; hot water washing and poorer<br />

substitution ratio<br />

These tend to be associated with natural fibres such as<br />

wool – presumably, synthetic fibres might tend towards<br />

values akin to those for plastic, or lower<br />

Notes Notes: Notes : The negative values here represent emissions ‘avoided’ or saved as a result <strong>of</strong> recycling<br />

Typical emissions for paper recycling have been adjusted to remove the element associated<br />

with avoided disposal.<br />
