We count with a broad network of independent consultants, technicians and university scientists in different countries. We believe that a project - be it the construction of a biogas plant or the elaboration of a strategic approach - to be successful needs a committed team. This is how we select and train our people.

2 Water and energy There are alternative systems making a smart usage of existing resources. Waste water can be cleaned and re-used. Energy can be produced from organic waste or energy crops. Lost heat can be transformed into electricity or utilised for cooling. These solutions tend to be smaller and to work in decentralised units. They supply a town or even only a factory. In modular applications they are especially apt for fast changing environments. Smart Utilities Solutions develops and applies smart decentralised utilities solutions with high efficiency. The philosoph hy Alternative systems Water and energy are necessary conditions for any development. Irrigation makes desert land produce crops, electricity facilitates production and enlightens our communities. Growing demand and scarcity drive prices for water and energy. But even where people could afford increased costs, utilities are not always available. Traditional central production and transport systems which have been built up at the beginning of the 20th century do not work where the demand has shifted to new places or has been growing fast.

3 Integrated project development In our projects we follow two main principles. First we strongly believe in an integrated economic-technical project approach. Second we always look after the most efficient, integrated usage of resources within the production system. How we work During the running time of construction projects, a classic conflict often arises between the responsible economists and the responsible technical engineer about "what is needed" and "what is budgeted". Therefore we make sure to understand from the very beginning of a project the underlying economical and technical assumptions. In an iterative process of technical design and cost analysis we look for the most cost efficient approach within the given framework. Efficient usage of resources requires a thorough understanding of the entire supply and demand side of a production site. If a company requires steam which today is produced in a boiler house it might as well opt for co-generation producing steam and electricity. Efficient usage of resources as well means looking after local technology and local resources whenever possible. Today much of the technology built in renewable projects like generator for wind mills or mixing systems for bio digesters come from Europe or the USA. We make sure that local resources are used as good as possible including the possibility of building up local manufacturers.

4 Services and busines ss areas The services we offer Technical feasibility studies Economical feasibility studies Elaboration of energy balances Project design and project management Project Controlling Technology selection Technology adaptation Supplier selection and negotiation Support over the entire construction phase Our main areas of activities Project management: We set up the entire project management structure to develop a project from the first idea to delivery. We bring in a team of economists, technical engineers and environmental experts. We look for a local partner or build up a local organisation. Consulting and interim management: With an experienced team and a network of partners we accompany technology entrepreneurs in building up their companies. Technology development: We are always looking for new technologies. Together with talented originators or engineers we organise necessary steps for large scale market production. We accompany performance tests and certification processes. Seed financing: We strongly believe that partnership requires risk sharing. Therefore we are also ready to invest into technologies and those partners we are cooperating with.

5 Biogas plant based on chicken manure A fully integrated agricultural company in Peru with c. 4 m egg producing hens, 1500 milking cows and 1500 ha productive area (asparagus and avocado) already operates a biogas plant. A second plant shall be financed by selling CO 2 certificates (CDM project). Further revenue potential is expected by integrating the plant in the fertilizing sourcing strategy of the company as hen manure after passing the biogas plant is better available for the plants and can be directly injected in the irrigation system. Example I: Biogas plant Smart Utilities Solutions designs and builds the entire plant including the energy and material flow management on the farm. Negotiating with international suppliers we could realize savings of up to 35% for main parts. 75% of the entire purchasing (by monetary volume) is done in the country. water gas storage gas treatment drier paperboard production Heater chicken breeding heater Biogas plant pre treatment post treatment chicken manure sand, feathers biogas plant solids to composting water with nutrients to irrigation

6 Technology research for motor developer A Brazilian motor developer with focus on robust multi fuel engines asked for global research on Biogas production technology Water-diesel-emulsions. Example II: Technology research Smart Utilities took a two folded approach. On one side we organized an international tender process for different biodigester technologies which allowed the customer to take advantage of low priced technology from China and New Zealand. On the other side we identified a new mixing technology based on cavitation. We evaluated different potential suppliers and followed up university research.

7 Example III: Isolate ed grid Isolated grid based on biogas In a remote part of Argentina the local government wants to introduce a gas grid. As the transport pipeline and possible other gas sources are far off we have been asked to design and calculate an isolated grid based on biogas. To cope with the demand side there is need of 20 plants 5 MW gas each. Due to relatively low price for land and corn the production costs for biogas would be based on a 10 years amortisation period on the level of imported LNG (10 $ / MBTU) which today is the only available alternative. If taking into account other sources for biomass like residential waste or waste from a slaughterhouses the cost can be further diminished. On the demand side upgrading the biogas to 98% methane would allow using the old devices like stoves or heaters and introduce the biogas as fuel. The local government currently is trying to raise funds to succeed with detailed engineering and construction.

8 Example IV: Integrated water an nd energy treatment Integrated water energy treatment Due to new environmental regulations new waste water treatment systems need to be built for slaughterhouses. Instead of a traditional aerobic biological waste water treatment which would increase the energy demand the facility could build an integrated waste-water-treatment-energy-system. The organic waste water stream is filtered so that a relevant part is directly used for fermentation and the production of biogas in a combined heat power plant (CHP). The remaining waste water is run through the aerobic phase which can now be planned much smaller and can be oxygenated with electricity from the CHP. The residuals from the water treatment can also be run through the fermentation. Heat or steam or cooling from the CHP can be used in the plants regular processes. With an additional gas storage the CHP can also be used as emergency generator. The concept has been developed for industrial slaughterhouses and fish wheat producers in Latin America. rack Organic waste grease trap grease hygienisation Waste water treatment primary clarification primary sludge Biogas plant activated Sludge tank production of utilities excess sludge gas tank use in farming or dewatering, drying, combustion, disposal Optional output: clarifier microgas turbine steam heat cooling energy electricity generatorr

9 Example V: water tu urbines Micro hydropower plants without dam Traditional hydropower plants make use of the potential energy of the water. They always require some kind of a barrage which goes together with high investments and maintenance costs. Environmental regulation further limits the use of these plants. If the kinetic energy of rivers could be used without any barrage (2 m/s stream, 2 m deepness) these small hydropower plants would meet a market with little limits. Together with several universities we evaluate necessary technology to build a prototype. We would monitor a potential pilot project with regard to the economics. In rural area hydropower plants would stand against diesel fired plants and could therefore afford higher initial investments if maintenance can be reduced to basics. This project is developed by Smart Utilities on its own account viewing the huge potential in India and Latin America. Examples for micro hydropower technology

10 Example VI: Integrated utilities waste management An industrial customer is planning different production facilities at one site including dairy farming, dairy products, meat and bio gasoline. The required over-all power for thermal energy was calculated with 20 MW. The different facilities have to be supplied with electricity, water, heating and cooling energy as well as steam. In order to reduce operational costs Smart Utilities Solutions was asked to design an integrated utilities and waste management system at the site. Based on an analysis of all incoming, internal and outgoing flows of material and energy an integrated production concept was designed where Energy and water re-use within the plant Amount of needed external utilities and Utilisation of waste streams was optimized. In order to find the optimal solution for such complex systems, Smart Utilities Solutions uses special mathematical tools that allow an efficient optimization of all operational parameters at once.

11 Example VI: waste wate er treatment Efficient waste water treatment technology A customer from the United Arab Emirates is looking for efficient treatment systems of residential waste water. Due to the specific climate and regional particularities the customer has unique requirements regarding water re-use scenarios and quality of treated water. Next to suitable technology the customer is also planning to invest in possible suppliers in order to produce chosen technology within the United Arab Emirates. After conducting an extensive market research and evaluation of existing technologies, Smart Utilities Solutions developed a suitable approach not only for the water treatment but also the later re-use. Furthermore, potential investments have been identified and evaluated for the customer. Example for used technology for waste water treatment In systems with limited space available it is necessary to use most efficient technologies. There are alternatives for the treatment of drinking water, as well as the treatment of black waters. In containerised systems either technologies based on microfiltiration or on chemical treatment can be used. In other cases as well as for the use of drinking water a biological treatment might be suffiecient.
