1 DES CHOIX INTELLIGENTS POUR UN AVENIR DURABLE SMART CHOICES FOR A SUSTAINABLE FUTURE Environmental technologies and innovation Luc Vriens, CEO Waterleau 2 0 M A R C H / M A R S PALAIS DES CONGRES MONTREAL CANADA eeas.europa.eu/canada/events/goinggreen2013

2 Canada / European Union / Belgium km² 3.4/km² km² 114/km² km² 342/km² Although, we Belgians, speak at least 3 languages, we know that: In Belgium, the DILUTION is NO SOLUTION for the POLLUTION Belgium has created a very performant environmental business

3 FIRE WIND CLEAN ENERGY From wastewater From sludge From biomass From waste CLEAN AIR Flue gas treatment Dust removal VOC & Odour control Biogas cleaning CLEAN WATER Drinking water Process water Waste water Reuse Desalination CLEANING UP Sludge treatment Medical waste Hazardous waste Municipal waste WATER EARTH

4 1000 references in 80 countries Saudi Arabia

5 Innovation 30 years of innovation in different fields of Environmental Technology Desalination and drinking water Municipal wastewater treatment Industrial wastewater treatment Organic waste Municipal solid waste

6 Desalination THERMAL Multi Effect Distillation MEMBRANES Reverse Osmosis No energy recovery Power consumption: 6.0 kwh/m³ 1990 Power consumption: 9.0 kwh/m³ Thermal energy: 7.5 kwh/m³ Electrical energy: 1.5 kwh/m³ Always in combination with powerplants (waste heat) Energy recovery with turbines Low pressure membranes Power consumption: 4,5 kwh/m³ 2000 Energy recovery with pressure exchangers Extra low energy membranes Power consumption: <3.0 kwh/m³

7 Desalination Global desalination capacity: 70 mio m³/day = 1/3 thermal + 2/3 membrane Total costprice of 1m³ dropped from a few dollars to less than 0.5 USD/m³ Typical project Reverse Osmosis (RO): m³/day

8 Desalination: More Renewable Energy Wind energy Solar energy Tidal energy

9 Drinking Water and Water Reuse Conventional treatment Membranes coagulation flocculation decantation sandfiltration storage, disinfection & distribution Still used today Since mid 90 s: sand filtration is replaced by membranes

10 Drinking Water and Water Reuse Conventional drinking water treatment Water reuse by sandfiltration and disinfection Saudi Arabia m³/d Morocco m³/d Macau m³/d Macau m³/d Water reuse by membrane filtration Water reuse by membrane filtration

11 Municipal Wastewater Treatment Conventional plants in the 80 s Large surface area required Open tanks, no odour control No biological nutrient (N&P) removal Low effluent quality (no tertiary treatment) No effluent reuse Low-energy efficient aerators No energy recuperation from the sludge No valorisation of the sludge High costs for sludge disposal Energy consumption: 2kWh/m³ Total costs: 0.5 /m³

12 Municipal Wastewater Treatment Modern plants Compact Covered with odour control Biological nutrient (N&P) removal Superior effluent quality (tertiary treatment) Reuse for irrigation Highly efficient fine bubble aeration Wind and Solar Energy Energy recuperation from sludge Sludge valorisation (drying & incineration) Low costs for sludge disposal Energy consumption: 0 kwh/m³ Total costs: 0.25 /m³

13 Municipal Wastewater Treatment Belgium PE m³/d Macau PE m³/d China PE m³/d Zhuhai - China PE m³/d

14 Industrial Wastewater Treatment 1980: Stella Artois Brewery Capacity: 3 Mio HL/year Water to beer: 12 HL/HL beer Organic load: 4 kg COD/HL beer Wastewater treatment Conventional Activated Sludge Hydraulic capacity: m³/day Organic capacity: 30 ton COD/day CAPEX: 12 Mio OPEX: 3 kwh/hl beer TOTAL: 2,0 /HL beer Sludge (@20%DS): 4 kg/hl beer

15 Industrial Wastewater Treatment Modern Brewery today Capacity: 3 Mio HL/year Water to beer: 3 HL/HL beer: 4 x less Organic load: <1 kg COD/HL: 4 x less Wastewater treatment Anarobic-aerobic treatment + water reuse Hydraulic capacity: < m³/day Organic capacity: 9 ton COD/day CAPEX: 4 Mio : 3 x less OPEX: 0.3 kwe/hl beer: 10 x less Total cost: 0,25 /HL beer: 8 x less Sludge (@20%DS): 0.25 kg/hl beer (10 x less)

16 Industrial Wastewater Treatment 300 Industrial plants in operation worldwide of which 100 plants for breweries

17 Organic waste of AGRO-industry Belgian A modern French fries factory can produce 60% of it s electrical and thermal energy requirements out of its wastewater and its organic waste new energy: + 4MWe organic waste Energy consumption: - 10MWe process water waste water new energy: + 2MWe + 4 MWth effluent influent water reuse

18 Organic waste of AGRO-industry Belgian A French fries factory processes 1 mio ton/year of potatoes A modern treatment plant of potato waste processes ton/year Energy production: 3 MWe Dry fertilizer pellets (organic + NPK): tons Clean water: m³ (reused in factory) Belgium Flanders

19 Kitchen and Restaurant Waste A city of 2 million inhabitants produces tons of Kitchen and Restaurant Waste per year: Too wet (20% DM) and too biodegradable for landfill Production of Green House gases Odour problem Dirty leachate

20 Kitchen and Restaurant Waste Out of tons per year, a modern treatment plant produces: Energy: 3 MWe Dry fertilizer pellets: tons Clean water: m³ Waterleau New Energy - Ypres - Belgium

21 Organic fraction of Household Waste A city of 1,3 million inhabitants produces tons of organic fraction of municipal household waste per year: Aerobic composting in the 80 s Aerobic composting consumes 1MWe

22 Organic fraction of Household Waste A dry anaerobic composting plant with a capacity of tons / year produces 4 MWe Dry anaerobic composting

23 Municipal Solid Waste Treatment Before 1980: Landfill No material recovery No energy recovery Soil pollution, water pollution, air pollution, smells,... Not sustainable (transfer of problems to future generations) Income from Gate fee: 5 /ton Energy prod: 0 /ton

24 Municipal Solid Waste Treatment From the 80 s: Incineration Some recycling No energy recovery No flue gas cleaning (only dedusting in Electro Static Precipitator) Not sustainable : inacceptable levels of air pollution (e.g. Dioxins) Bad reputation! Income from Gate fee: 25 /ton Energy prod: 0 /ton

25 Municipal Solid Waste Treatment From 2000: Waste to Energy 75% recycling Energy recovery (electricity) Complete flue gas cleaning (also dioxine removal) Sustainable business Zero emissions to air and water Income from Gate fee: 100 /ton Energy prod: 20 /ton TOTAL: 120 /ton

26 Municipal Solid Waste Treatment Waste to Energy projects in emerging markets Hai an - China tons per year - 15 MWe Shanghai - China tons per year 18MWe Liaoyuan - China tons per year 16MWe Binzhou - China tons per year 16MWe Gate fee: 20 /ton Energy prod: 10 /ton TOTAL: 30 /ton

27 Conclusions Within 30 years, environmental technlogies have become Much more performant Much more energy efficient Less CAPEX and OPEX consuming Business environment has changed as well Much more competition Much more performant Necessity to stay LEAN and MEAN
