  1. Hazardous Waste Management:Singapore and other Asian examples ISWA Hazardous Waste Seminar and Workshop Singapore, April 2012 Presented by: Rick Reidinger CEO, Eco Special Waste Management Portfolio Director, Navis Capital Partners

  2. Hazardous Waste Management in Singapore

  3. Background • Singapore has a small land area and dense population • Industries: chemicals, electronics, semiconductor, petrochemicals, refineries, engineering, offshore engineering/ rig-building, port, general manufacturing, food industries, pharmaceuticals trade • Government has strong commitment and ability to ensure a clean environment • Approximately 1 million m3 of hazardous waste generated per year • Solvents, oils, acids, coolants, slop oil, sludge, obsolete products, medical waste, etc

  4. Government Strategy for Control of Hazardous Waste • Upstream land planning and building plan control; • Avoid generation of intractable wastes; • Encourage waste minimization; • Encourage waste reuse, recovery and recycling; • Regulate collection, treatment and disposal; • Licensing of all Toxic Industrial Waste (TIW) Companies; • Monitor and audit collection, treatment and disposal; and • Promote and support educational and training programmers

  5. Licensing and Control under NEA Cradle to grave approach under the Environmental Public Health (Toxic Industrial Waste) Regulations • Generation and storage - specific list of Toxic Industrial Waste, labeling, containment, emergency response plan, etc • Collection and transport – consignment note system (e-submission and tracking), transport approval, treatment company handles transport • Treatment - licensed treatment companies, special emission standards, frequent (monthly) site inspections, waste approved on case by case basis • Disposal - of stabilized residues to Pulau Semakau, must meet key criteria (metals, Hg, etc) • Also applies to biohazardous waste- plus additional requirements on storage and handling (color coded bags, etc)

  6. Special Waste Incinerator Emission Standards • Importance of specific and stringent standards for waste incinerators

  7. A fully private hazardous waste market Chemical plant Electronics factory Pharmaceutical facility Generators Long term and spot contracts, variable pricing Private TIW contractors Treatment company A Treatment company B Treatment company C Variable sizes, capabilities, technologies, risk profiles, client base, etc NEA- regulation, standards (mainly output based), licensing, enforcement Regulator

  8. Results of the Private Market • Prices- have fluctuated widely based on market conditions, output of industries, and capacity of TIW companies • Capacity development and replacement- smaller, more flexible facilities with a range of technologies • Government involvement- none, with the exception of ensuring a level playing field and environmental standards • Environmental impact- some improper practices, but generally acceptable and much better than most other countries in region • Economic impact- has created a robust local industry that is in a good position to expand regionally

  9. Hazardous Waste Treatment Facilities More than 100 licensed contractors PureChem Veolia Rotary kiln incin. Physical-chemical Solvent recycling TechnoChem Rotary kiln incin. Etchant Treatment SembCorp Medical waste incin NSL Oilchem, Waste oil recovery Incineration ECO Special Waste Fluidized bed incin. Thermal FCE/ ATFE Solvent Recycling Chem-Solv/ Aroma Incineration Solvent recycling Physical-chemical SUT Sakra Fluidized bed incin Biological treatment Cramoil Rotary kiln incin Neutralisation

  10. Hazardous Waste Facility Example- Eco Special Waste Management • A leading special waste management company in Singapore. Business segments: • 65% hazardous industrial waste management • 20% municipal wastewater sludge treatment • 15% industrial general waste management • 70% of business is treatment, 30% of business is recycling. • 270 staff. Chemists, chemical engineers, technicians, operators, mechanical/ electrical engineers (and one economist!) • High capital intensity/ physical operations. One large integrated facility which functions on the basis of “industrial ecology”

  11. Capital intensive, high technology facilities are required for proper treatment Fluidized bed Incinerator Solvent Recovery Oil Recovery Thermal Waste Water Treatment System Physical chemical treatment Storage Tanks

  12. Eco SWM- Integrated Facility • 6 Ha in Tuas • Currently undergoing major expansion and investment in new facilities • Capable of handling more than 350,000 tonnes of hazardous waste, sludge, and industrial waste per year

  13. New Sludge Treatment Plant Train 6 under construction at Eco Bag Filter H/E-1 REFRACTORY LINING Bag Filter House DRYER H/E-1 Dws/Ds Feed Hoppers Circulation Fan INC with hot air pipes T-6 DWS/DS Belt conveyor completed INC AND H/E-1

  14. Selected Examples in other asian countries

  15. Hazardous waste management industry in Asia • Driven by increasing industrial output, generation of difficult to manage and highly toxic by products • Governments around the region have enacted and enforced (or not) regulations for control of hazardous waste • Examples of sub-segments: • Physical chemical wastewater treatment for hazardous inorganic • Activated carbon regeneration • Oily sludge and slop separation (MARPOL) • Incineration of toxic organic chemicals • Solvent distillation and recovery • Specialized hazardous waste landfill (stabilized and highly contained) • Membrane separation of oils and chemicals • Well developed industry in the US, Europe, and Japan- emerging in Asia • Proper treatment and thus high treatment cost leads to high technology facilities and investment if government enforcement is good, and dumping or illegal practices if enforcement is poor

  16. Hong Kong: CWTC (Veolia) • Opened 1993 • Capacity 100,000 tpy • Incineration at 700-1200 degrees • Very strict performance requirements • Government bears 54% of variable operating costs and all capital costs

  17. China: Shanghai (SwireSita) • SwireSITA Waste Services (SSWS) facility in SCIP- opened in July 2007 • 60,000 tonnes per year incinerator (rotary kiln); largest HW incinerator in China • Capable of handling a wide range of wastes and characteristics • Liquid, solid, gas • All sorts of packaging • No limit on chlorine content, lower calorific value, water content, ash • Emissions and waste disposal meet current EU standards, anticipate future Chinese requirements (bag filter, SNCR, 2 scrubber system, dioxin treatment) • Recovers energy and steam • RMB575 million investment

  18. Indonesia: PPLI (DOWA)
