I. Waste Generation and Disposal

Daily Waste

• Generation : 1,454tons/day (in 2015)
• Type : Household Waste, Food Waste, Etc.
• Disposal : Recycling 785t/d, Incineration 598t/d, Landfill 71t/d

→ Public Facilities : 1 Landfill, 3 Incineration Plants, 2 Food Waste Disposal Facilities → Private Facilities : 5 Landfills, 6 Incineration Plants, 181 Recycling Plants

Industrial Waste

(Landfill) Mixed Sanitary Landfill

• no food waste landfill since 2005, but recycling
• separate treatment for recycling waste by type

(Incineration) Separating Combustible Waste

• incineration an combustible waste since 2000

※ separately keeping, collecting and disposal of waste by type, nature and condition

Social Condition Policy of Advanced Waste Treatment Rapid Inflow of Population, Building an Industrial Complex, Increased amount of Waste

• Incineration Plant : 650tons/day(3 plants)

☞ medium∙high pressure steam 1,200tons/day

• Food Waste (+ Livestock Manure)

Disposal Facility : 150tons/day ☞ row pressure steam 70tons/day

• Landfill : area143,000㎡

☞ Landfill Gas 6000㎥/day

• Food Waste (+ Swage Sludge)

Disposal Facility : 390tons/day

☞ bio methane 26,000㎥/day

STEAM BUSINESS STATUS

• Background
• Discovering an alternative energy source
• Reducing greenhouse gas
• Expanding regional economic and budget expansion

⇒ Establishing mutual trust between administration and company, active introduction of energy efficiency technology

• Measure
• Establishing the system

: Steam supply facility and Supply method, Selecting recipients

• Signing the facility use agreement

: Ulsan City, Hyosung inc. (Technical advisory → EIP business group )

• Improving the energy system for expanded incineration plants

(electricity →High Pressure), Economic feasibility doubled

• problems overcome
• applying construction cost within steam price( installing the pipe

by recipients)

• persuading BTO construction companies for expanded

incineration plants,

Regional economy vitalization, a leading model of low-carbon green growth
