We performed a literature study on residues and waste potentials in 2050 for five main categories:

• Oil and fat residues and waste

• Forestry residues and wood waste

• Agricultural residues

• Wet waste and residues

• Dry waste

In our study we analysed the potential for the most important sub­categories of each main category. After obtaining the literature values for the potential of each residue and waste (sub)category, we performed three additional analyses to arrive at the final residue and waste potential figures:

1. We adapted literature projections for 2050 for manure and waste animal fat potential to reflect the meat consumption level described above.

2. We altered the dry waste potential from municipal solid waste (MSW) to reflect the fact that not all MSW is renewable and that some MSW is wet and some is dry.

3. We updated the recoverable fraction, the share of residues and waste that is available for bioenergy production, for some of the categories because they were inconsistent with other developments such as im­proved future economic feasibility of residue collection or our study’s framework of closed nutrient loops. The recoverable fractions used always take into account other uses, e. g. the use of wood residues for production of fibre board, and sustainability considerations.

The results of our analysis are displayed in Table 4. Table 4 also in­cludes data on the used recoverable fractions per subcategory. In some cases, the recoverable fraction was implicitly included in the analysis of the literature sources we consulted; in those cases the value cannot be reported. It should be noted that the reported recoverable fractions do not include the residue-to-product ratio, which is a measure of how much resi­due is produced per quantity of main product. This ratio was implicitly included in the analyses of the consulted literature sources.
