ENVIRONMENTAL, SOCIAL AND GOVERNANCE BENEFITS What are the social, environmental and/or governance benefit(s) and impact(s) resulting from your Best practice?

3 Greenhouse gases will make up only 269 equivalent tons of carbon annually, i.e., 90% less than the previous plant. These emissions are completely offset and Aquaviva uses different procedures and technologies to achieve this. The treatment plant has 4,000 sq. m of solar panels making it the largest solar farm project in the Maritime Alps. Drying the sludge resulting from wastewater treatment will also contribute to the offsetting effects. Dry sludge will then be treated and recycled as natural fertilizer for agriculture in the region.

4 Year: 2017 SHOW CASE TITLE: Injecting biométhane into natural gas network COMPANY NAME: SUEZ Category : Circular Economy Country of the Best Practice: France Company name: SUEZ Industry: Water / Waste Turnover (2015): Worldwide: 15.1 billion Asia Pacific: 3,997 million Workforce (2015): Worldwide: 82,536 Asia Pacific: 9,500 Singapore: 34 BACKGROUND Please briefly describe your line of Business. Who Initiated this Project? What drove the company buy into this initiative? On 8 September 2015 were produced the first cubic metres of biomethane injected into the local natural gas supply network. The first event of its kind in France was attended by Ségolene Royal, Minister of the Environment, Energy and Marine Affairs, responsible for International Climate Relations. The Biovalsan 1 project as it is known, is part of the proactive environmental policy adopted by Strasbourg. The process designed by the two partners consists in purifying the biogas produced by the decomposition of treatment sludge using a membrane ultrafiltration system to separate the various elements. The biogas then becomes biomethane, which is perfectly compatible and miscible with natural gas. The project will produce 1.6 million cubic metres of purified biométhane per year, or the equivalent consumption by 5,000 BBC-certified (lowenergy building) homes. Headquarter (country): France Company Website : Company logo: Illustration representing the Biovalsan project 1 The name Biovalsan is formed from three French syllables of words describing its purpose: biomethane, energy recovery and its sanitary character.

7 Year: 2017 SHOW CASE TITLE: Degrés Bleus, an ecological heating solution COMPANY NAME: SUEZ Category : Circular Economy Country of the Best Practice: France Company name: SUEZ Industry: Water / Waste Turnover (2015): Worldwide: 15.1 billion Asia Pacific: 3,997 million Workforce (2015): Worldwide: 82,536 Asia Pacific: 9,500 Singapore: 34 BACKGROUND Please briefly describe your line of Business. Who Initiated this Project? What drove the company buy into this initiative? The Degrés Bleus solution, developed by SUEZ, involves supplying all or part of the energy needed to heat a building through a system that collects heat from the wastewater treatment network. This solution recovers local resources, achieves greater energy self-sufficiency and reduces greenhouse gas emissions by 50 to 70%, when compared against traditional solutions. On average, the temperature of the wastewater (1) flowing through our sanitation networks is 11 C to 20 C, all year round. A heat exchanger (2) is installed in the wastewater network. Made of stainless steel plates, this heat exchanger is filled with a heat-carrying fluid (3) and is connected, in a closed circuit, to a heat pump. When the glycol water heat-carrying fluid comes into contact with the heat exchanger, its temperature rises from 4 C to 8 C. It then feeds the heat pump, which is connected to the building s heating and/or domestic hot water circuits (4). Headquarter (country): France Company Website : Company logo: OBJECTIVE(S)

8 Which Best Practice objective(s) does the company want to achieve with Your Project? This solution aims to transform wastewater into a source of heat for our towns and cities. Since the temperature of the wastewater flowing through our sanitation networks is 11 C to 20 C, all year round, it means that it constitutes a major source of renewable energy, right in the heart of our towns and cities. APPROACH Which were the critical phases of Your Project implementation? Were other department(s) or function(s) involved in your project? RESULTS Was your project successful? Which tangible results could be highlighted? Also please state any challenges and obstacles encountered if any. Several sites have decided to adopt Degrés Bleus to reduce their environmental footprint and optimize their energy consumption. These even include the Elysée Palace and its outbuildings on Rue de l Elysée. The solution helps reducing their fossil energy consumption by 63%, thus reducing CO2 emissions by 206 metric tons per year. A pioneer in this technique, the municipality of Levallois also selected this solution for its aquatic center. Thus, by using the wastewater network adjacent to the center, the city reduced its energy consumption by 24% and greenhouse gas emissions by 66% while maintaining the temperature of its pool water.

10 Year: 2017 SHOW CASE TITLE: Helping the environmental performance of industrial customers COMPANY NAME: SUEZ Category : Circular Economy Country of the Best Practice: France Company name: SUEZ Industry: Water / Waste Turnover (2015): Worldwide: 15.1 billion Asia Pacific: 3,997 million Workforce (2015): Worldwide: 82,536 Asia Pacific: 9,500 Singapore: 34 Headquarter (country): France Company Website : Company logo: BACKGROUND Please briefly describe your line of Business. Who Initiated this Project? What drove the company buy into this initiative? In Great Britain, SUEZ is helping Heineken, the world s third largest brewer, to face its environmental challenge by reducing the environmental footprint of its effluent treatment plant. In 2009, one year after the purchase of John Smith s Brewery, SUEZ was awarded the contract to operate and maintain the brewery s effluent treatment plant. A formidable challenge as the plant regularly exceeded the ammonia levels permitted by the UK Environment Agency. Some 90% of all non-compliances were found to be due to the production of ammonia. Furthermore, far from removing this pollutant, the plant was actually producing more ammonia! A strategic plan was therefore developed and promptly implemented to meet the legal requirements of the Environment Agency. In September 2011, a solution was installed at the inflow to the plant to reduce the suspended nitrogen particles responsible for the ammonification. Along with this first initiative, SUEZ was working closely with Heineken to identify opportunities for savings and to move forward to further optimize the effluent treatment plant. SUEZ offered a solution that worked: it commissioned to change the gas engine to run on gas, thereby allowing the anaerobic digester to work flat out. It refers to a methanisation process that reduces the ammonium content while producing energy! The biogas produced is then recovered and sent to the plant s boilers to produce steam, or it can be used to produce electricity.

APPROACH Which were the critical phases of Your Project implementation? Were other department(s) or function(s) involved in your project? RESULTS Was your project successful? Which tangible results could be highlighted? Also please state any challenges and obstacles encountered if any. SUEZ s technological mastery not only allowed Heineken to meet the expectations of the Environment Agency, it led to the successful production of energy from biogas and the optimisation of its environmental footprint! A real challenge which the pleasantly surprised Environment Agency summarised as follows: SUEZ has clearly improved the management and control of the plant. It has succeeded in implementing a solution that no one had thought of before!

12 KEY SUCCESS FACTORS CONTRIBUTION TO CORPORATE PERFORMANCE Describe the concrete measurable benefits and outcome of Your Projects (if possible give numerical results) The most measurable benefit is the biogas produced on the site that is then recovered and sent to the plant s boilers to produce steam, or it can be used to produce electricity. Following a period of optimisation, no further non-compliance issues due to ammonia have been observed, while BOD (biological oxygen demand) and suspended matter levels have decreased significantly. ENVIRONMENTAL, SOCIAL AND GOVERNANCE BENEFITS What are the social, environmental and/or governance benefit(s) and impact(s) resulting from your Best practice? This technological innovation gives Heineken a glimpse of the treatment plant of the future: more than just a decontamination plant, one able to produce multiple resources and select the most economical solutions in terms of energy and raw materials. in addition, it is perfectly in line with our commitments to adapt to the consequences of climate change by saving energy.
