Definition of BATBest Available Techniques

• Technique includes both technology used and the way the installation is

designed, built, operated and decommissioned

• Available techniques are those developed on a scale which allows

implementation in the relevant industrial sector under economically and technically viable conditions

• Best Means most effective in achieving a high level of protection of

environment as a whole

Annex 41. Use of low-waste technology2. Use of less hazardous substances3. Furthering of recovery and recycling of

substances generated and used in the process and of waste

4. Comparable processes, facilities or methods of operation which have been tried out with success on an industrial scale

5. Technological advances and changes in scientific knowledge

6. The nature; effects and volume of emissions concerned

Annex 4 cont.

7. Commissioning dates for new or existing installations

8. Length of time to introduce BAT9. Consumption and nature of raw material used in

process and energy efficiency 10. Need to prevent or minimise the over all impact

of emissions 11. Need to prevent accidents and to minimise

consequences 12. Information published by Commission (art 16(2))

Art 10BAT and Environmental Quality Standards

• Where an environmental quality standard requires stricter conditions than those achievable by the use of BAT additional measures shall be required which might be taken in order to comply with the EQS

BREF Document onEconomics and Cross-Media Effects

May 2005

• Methodologies for assessing which of alternative techniques is “the best”

• 9 guidelines for applying these methodologies

• Assessment on Economic Viability in a sector

Cost effectiveness analysisBalance of costs and environmental benefit

GL7Define cost components

Guideline 1Necessary information to scope and identify

alternative techniques

• Selection of raw material• Process design• Process control• End of pipe technology

Guideline 2Inventory of emission and consumptions

• Pollutants released (air and water)• Used energy• Produced waste

• Monitoring data from existing installations• BREF documents• Research reports• Data from Pilot plants• Information from equipment manufacturers

DATA QUALITY

Guideline 3Estimate environmental effects

• Human toxicity• Global warming• Aquatic toxicity• Acidification• Eutrofication• Ozone depletion• Photochemical Ozone creation potential• Etc????

Guideline 4How to interpret the cross-media conflicts

• Simplistic approach- just compare• Compare with European totals• Compare using EPER

• Compare to benchmark• Environmental Quality • Local considerations• Long term irreversible effects contra Short term

reversible effects• Priority to persistent, bioaccumulative, toxic and

carcinogenic substances

Costs for Environmental Protection

• Calculate cost efficiency• Balancing costs and Environmental

benefits

Guideline 5Scope and identify alternative techniques

• Selection of raw material• Process design• Process control• End of pipe technology

Guideline 6How to gather and validate cost data

Sources of cost data

• Industry• Technology suppliers• Authorities• Consultants• Published information (BREF)• Comparable projects from other industries

Data Quality Transparency

Guideline 7Define the cost components

Investment costs• Installation costs

Operating costs• Energy• Material• Labour cost• Maintenance

Guideline 8Process the cost information

• Establishing prices in the base year (Inflation)

• Discounting• Interest rate• Calculating annual costs

Cost per unit of productCost per unit of reduced emission

Swedish practice

• Interest rate, 4-6 %• Depreciation, Economical life time,

– 10-20 years

Guideline 9Attributing costs to environmental protectionBalancing Costs and Environment Benefits

Communication Analysis• A working group (incl. all authorities with

responsibilities for traffic issues and Sw. EPA)

Option 3 Solution (BAT)

Allocation of gas to one furnace and oil to the other.

Installation of Low NOx burners in the gas fired unit, installation of SCR at the oil fired unit

A Total NOx reduction from CDU of ~70 % to a reasonable cost (less than 50 SEK/kg reduced NOx)
