Treatment of waste – Statistics Netherlands 3
Classifications of waste treatment R/D codes
• Waste Framework Directive (2008/98/EC) • Waste treatment related activities are
classed as recovery (R) or disposal (D)

R and D codes (recovery operations)
• *R1 Use principally as a fuel or other means to generate energy
• R2 Solvent reclamation/regeneration• R3 Recycling/reclamation of organic substances which are
not used as solvents (including composting and other biological transformation processes)
• R4 Recycling/reclamation of metals and metal compounds• R5 Recycling/reclamation of other inorganic materials• ….etc

Measure treatment of other waste flows• National monitoring: Measure the waste treatment from a
sector according to a minimum standard • Very detailed, combination of type of waste and origin of
waste• Where to measure? In NL: Hybrid

Measure at generation• Industry• Enquire first step of treatment (recycling,
sorting, or recovery, landfill, etc)• Type of waste (Eural code)• Amount of waste

Treatment of waste – Statistics Netherlands 9
Measure at generation (2)
• Need good knowledge of waste management and constitution of mixed waste
• Make assumptions Separate collected waste is recycled (for the Netherlands)
• Mass balances for pre-treatment

Treatment of waste – Statistics Netherlands 10
Scope issues and specific issues for industrial waste
• Include by-products (waste from an industrial activity that is directly usable in industry)• For instance: Sulphur from desulferization in
petrochemical industry• Beetroot pulp and treacle• Account for 50 % of total industrial waste• Including those boost recycling percentage
• Specifically include internal treated waste• Example: On site waste incineration / landfill• On-site recycling in EU is not waste

Treatment of waste – Statistics Netherlands 11
Generation to treatment: conclusion
• Large survey• Link to final treatment sometimes difficult
(but do-able with assumptions)• Mass balances might be needed
• Imports need to be monitored

Solid municipal waste
• 12 plants• Direct survey of waste input
(mass and caloric value!) and electricity and heat output
• Collaboration with industry and statistics
• Renewable fraction determined at national level from waste statistics
• Waste statistics have an annual sample survey on the composition of household waste
![Page 16: Reuse and recycling of industrial waste · 2012-04-16 · Treatment of waste – Statistics Netherlands 10 Scope issues and specific issues for industrial waste • Include by-products](https://reader033.vdocuments.site/reader033/viewer/2022041608/5e35c0273324ed7cd678207f/html5/thumbnails/16.jpg)
Treatment of waste – Statistics Netherlands 15
Landfill
• ~ 50 landfill sites with production of biogas that is used
• Mostly electricity production, sometimes also production of heat or natural gas
• Type of waste and amounts that are disposed
• Origin of waste is unknown…

And relations between waste and renewable energy
• Sewage sludge: ~ 90 sewage sludge purification plants
• Generate waste, but also generate biogas• Data collection via cooperation with waste
water statistics of Statistics Netherlands
• Co-digestion of Manure• Waste treatment, but also electricity
production• About 80 sites• Produce electricity• Receive data on the electricity production
from administrative files used for the subsidies
• Co-firing in electricity production (wood chips)

Conclusions
• Choose point of view (from generation or from treatment)
• Generation:• Generation, type of waste and first treatment• Mass balances for some pre-treatment steps• Construct final treatment
• Final treatment (few companies)• Origin; type of waste; amounts• Capacities• Includes imports• No idea of waste losses (exports, illegal dumping, etc)
• Best option: Both. Link together!
