Retrofitting actions at Torrelago (Spain) district are coming to an end and a new time for reflection, analysis and assessment is about to start. CITyFiED is at the heart of Laguna de Duero (Valladolid, Spain) and has established the foundations towards a more sustainable development of the city and healthier urban environments.
CITyFiED has embraced the Torrelago residents in a democratic process to take part and decide on the renovation actions. At the same time, the CITyFiED representatives have ensured that the retrofitting investments all made economic sense to the residents so they can benefit from them. In a truly cooperative approach, CITyFiED representatives and residents have carried out an extensive demonstration action at Torrelago district from June 2014. All of the main economic and technological aspects in terms of building retrofitting, district heating system upgrade, integration of renewable energy sources and monitoring have been addressed by means of a systemic approach in order to achieve not only significant energy savings and very low CO2 emissions but also remarkable improvements in the residents’ comfort conditions.
Torrelago district renovation means the retrofitting of 143,025 m2 of living space and achieving 1,488 dwelling retrofitting actions for meeting the CITyFiED targets, i.e. reducing the energy demand up to 40% and avoiding at least 3,500 tons of CO2 emissions per year. The 31 buildings have been retrofitted with an external thermal insulation composite system, and the application of the finishing coat with primer and paint coating is only pending in 5 buildings. Dismantling scaffolding will be finished by May 2018.
In parallel to the building renovation action, the old energy system composed of two independent gas-based district heating networks has been upgraded. One of the previous gas boiler rooms has been replaced by a new biomass boiler room of 3.5 MW and the two networks have been merged to build a new multi-source (biomass and gas) district heating system that covers the 80% of the thermal demand with renewable energy sources. In addition, new variable flow pumps, heat exchange substations, individual smart meters and thermostats have been installed, together with a micro-cogeneration system to generate 33 kW of power and 73.4 kW of useful thermal energy.
After the large renovation action, one full year monitoring campaign is approaching and the CITyFiED monitoring platform is ready to collect information from the new energy systems and deliver environmental, technical, economic and social key performance indicators by March 2019.
Energy efficiency is taking its place as a major energy resource in Laguna de Duero city to achieve sustainability and growth targets. Indeed CITyFiED investment in Laguna de Duero, more than 16.5 M€, has provided many different benefits to citizens and other local stakeholders. Whether by directly reducing energy consumption and associated costs, which can enable investment in other goods and services, or facilitating the achievement of other objectives, e.g. making indoor environments healthier or boosting industrial productivity
Citizens, as main users of the city environment, have clear benefits in their daily: raising the economic activity in the city, which has led to a reduction of unemployment with 50 new jobs created in the CITyFiED context, enhancement of their environment and quality of life, and also to be on board for the transition to the concept of smart city of the future, with more comfort at city level and more technology at the service of the citizen. Even utilities and other energy providers benefit in a variety of ways from CITyFiED energy efficiency measures. Direct benefits include lower costs for energy generation, transmission and distribution, improved system reliability, dampened price volatility in wholesale markets and the possibility of delaying or deferring costly system upgrades.
CITyFiED actions in Laguna de Duero has reached more than 4,000 inhabitants that directly benefit from the project actions and their different testimonies on the district retrofitting actions play a key role in the deliberations of CITyFiED representatives. Reducing energy consumption and CO2 emissions is not only about adapting new technologies, but ensuring that these technologies are also being accepted by the public. Being able to talk about concrete examples that have proven to be efficient allow us push forward energy retrofitting projects and solutions beyond CITyFiED.
The importance of the train from an economic point of view is beyond dispute. It emerged as one of the most extraordinary innovations in the Industrial Revolution, because although it is true that the first steam locomotives had already been created before, it was during this period when the potential of this new means of transport could be seen.
Over the years, it has become one of the preferred means of transport for citizens, because of its safety and speed, only surpassed by the airplane. Furthermore, in contrast to the use of private vehicles, rail service contributes to fuel economy per passenger and is therefore more sustainable than other means of transport.
According to data from ADIF (Administrator of Railway Infrastructures), in Spain a train passenger consumes 5 times less litres of petrol equivalent per kilometre than traveling by car, and 20 times less than traveling by airplane. Or, for example, transporting one tonne of goods by rail consumes 4 times less litres of petrol equivalent than by road, and 1,380 times less than by air.
But, what about the construction of the railway infrastructure necessary for the movement of trains? Is it sustainable?
This was the premise of the LIFE HUELLAS project, led by CARTIF, together with the companies Vias y Construcciones and IK-Ingeniería and the University of Granada. Its objective was to improve the construction process of railway tracks in terms of their environmental impact, with special emphasis on those aspects that affect climate change.
It should be borne in mind that the railway infrastructure is made up of civil works such as bridges, viaducts, tunnels and service roads, and of the superstructure, made up of rails, sleepers, fastening material, and electrification, signalling and track safety installations. The production, construction and maintenance of all this infrastructure has a high environmental impact.
The LIFE HUELLAS consortium considered that life cycle assessment techniques, combined with intelligent data analysis, could help reduce the carbon and water footprint of railway infrastructure works by 10% and 5% respectively.
After four and a half years of intensive work, the project has managed to reduce an average of 12.9% of the carbon footprint and 14.1% of the water footprint per kilometre built in the works that have been used as pilots, i.e. better results than expected. Quite a success.
The project began with an exhaustive collection of basic information to analyse the environmental impact of the construction of railway networks, based on previously identified variables. Later, participating companies focused their efforts on studying the transformation of environmental impact into carbon and water footprints, through the development of a consolidated assessment methodology.
From this compilation, a smart tool will establish different planning alternatives applying computational intelligence techniques and showing specific values of footprint and previously selected environmental indicators. That is to say, the objective is to help in the decision-making process during the planning phase of the works.
Furthermore, the research team has developed a free online tool that provides a detailed environmental diagnosis of the processes involved in the construction of this type of infrastructure. This tool, available on the project website www.life-huellas.eu, allows the development of railway projects with not only economic, but also environmental and social criteria.
For the development of both tools, the consortium has exhaustively studied more than 460 project units and a collection of relevant sustainability variables and indicators, grouped in:
Environmental indicators: carbon and water footprint, acidification potential, photochemical oxidation and eutrophication.
Social indicators: improving working conditions, health and safety, human rights, governance, community infrastructure and job creation.
Economic indicators: project costs.
Tests were carried out during the demonstration phase of the project in two real works; on the one hand, the Ponte Ambía (Orense)-Taboadela (Orense) section of the Madrid-Galicia high speed line for the track infrastructure, that is for the earthworks (embankments, trenches, tunnels, etc.) and for the factory works (bridges, drainage, viaducts and level crossings); and on the other hand, the Antequera (Málaga)-Loja (Granada) section, for the track superstructure over which the trains run, whose main elements are ballast, sleepers, rail, electrification and signalling.
With the aim of contributing to these processes in terms of sustainability, the consortium has compiled in a guide of Good Practices the main conclusions of the experience acquired during the development of the project, as well as the different sustainable alternatives proposed.
Although LIFE HUELLAS project has already been completed, railway works on which it has been validated have effectively reduced the carbon and water footprint of their construction phase, contributing to the environmental improvement.
In addition, free access to the calculator will remain available at www.life-huellas.eu for anyone to use. You can also find us at networking and dissemination events, transferring gained knowledge, since the objective now is to promote replicability by communicating obtained results to other companies and sectors. For example, many of the railway infrastructure construction operations are common to those that build other infrastructures, such as roads, so they can also benefit from the results of the project.
Industry is one of the sectors with a highest energy demand, being the fossil fuels the main energy source used in the most of the industrial processes. The utilization of this type of fuels in the manufacture process of the industries generates a waste heat that is not usually used, hence these processes are considered as inefficient. Nevertheless, this waste heat can be recovered (and in many cases reincorporated into the same process) by using new strategies and equipment. Therefore, the optimization of the industrial processes and the implementation of renewable energies in them can contribute to reduce the harmful impacts of the energy systems to the environment, while reducing energy consumption.
In addition, it has to mention that the energy recovery contributes to the reduction of production costs of the industries and consequently these gain in competitiveness. However, energy recovering is not easy since it requires of high performance technology and best practices of operation. Furthermore, many factories have complex and autonomous processes that are unlinked to each other or integrated into their environment. On the other hand, each product and manufacture process are specific to each industry so that it is difficult to find a global solution that encompasses energy reduction, renewables integration and energy recovery through a more efficient use of resources, cleaner manufacturing technologies or the recovery of resources.
Traditionally, factors that were taken into account in manufacturing processes were economic, management, production, etc. However, this situation has changed in recent years. Energy efficiency and sustainable management are fundamental aspects that many companies have incorporated in their processes. Aware of that reality, CARTIF is accompanying the companies to incorporate in them the “Factories of Future” concept. An example of work done is the REEMAIN project.
CARTIF moves toward zero carbon manufacturing and Energy Efficiency2.0 through the intelligent employment of renewable energy technologies and resource saving strategies that consider energy purchase, generation, conversion, distribution, utilization, control, storage, re-use in a holistic and integrated way.
From the REEMAIN project experience, we have prepared a brief brochure, in which we have highlighted 13 efficiency measures implemented and tested in three factories, one from agrofood sector, another from textile and one more from iron foundry. These measures were classified into renewable energy integration, energy recovery, recycling and ecological materials use and production, process and product optimization.
Each measure is presented in a short and visual way and is composed of title, summary, savings achieved and key factors for a success implementation. Last input is a recommendation from our side to encourage the industries to replicate the measures already applied in the manufacture process of the democases in order to achieve similar results that in REEMAIN project.
Finally, under the section “Extrapolation to other factories” the replication potential of the measures has been quantified taking into account the next four main factors:
Process of implementation: This item is associated to the investment required for the implementation of the efficient measures, corresponding a high score with a low investment requirement.
Process criticality: This item has in consideration the increase in the complexity of the manufacture process as well as a reduction of the reliability due to the installation of new equipment in the industries. An efficiency measure with high score indicates few or null operation changes, e.g., being easily by-passing in case of breakdown or during the maintenance works.
Expected savings: This item is related to the savings quantification based on different factors
Investment return: This item considers the cost savings and feasibility of the installation in economic terms.
Brochure ends with a visual summary of the total savings achieved in the three factories that were part of the project.

It has been estimated that 25%of global population will inhabit countries affected with a continuous shortage of fresh water by 2050. Consequently, facing the objective described in the SDGS is a real challenge and must be tackled by every member of society.
Water demand is relentless rising with a continuously growing global population and as a direct consequence waste and chemicals derived from water conditioning for human consumption are also an increasing threat. More than 80 % of waste water is currently being discharged to natural water flows without any treatment as an average value considering low and high-income countries. This uncontrolled drainage has a huge adverse impact on human health, economic productivity, fresh water natural resources and ecosystems, according to ‘The United Nations World Water Development Report’ from 2017.
Sustainable water management is an essential tool for achieving the water objective in SDGs and every affected agent must be fully compromised for getting free-contaminant water accessible for every human being. Waste water treatment and reuse is key to integral water cycle management and it has amazing benefits for society.
A viable and alternative option for low volume waste water treatment, for example for small and medium size municipalities, is the use of constructed wetlands, imitating natural systems in which water depuration comes from chemical, physical and biological processes occurring thanks to the interaction in soil-water ecosystems.
Constructed wetlands are designed and built so that plant growing in shallow ponds and channels allow a natural ecosystem establishment able to filter and transform contaminants in the water flowing across the wetland.
These alternative depuration systems are considered human made because they are designed and built according to different parameters. Natural depuration mechanisms are imitated but in this case the wetland is sealed in a waterproof manner in the interface soil-wetland so that no waste water is drained towards the natural soil before depuration occurs. Plants and soil substrate are selected according to the location and climate conditions. An important consideration for choosing the vegetable cover is that these plants should be able to tolerate and assimilate a high concentration of contaminants.
Wetland depuration system consists on water flowing across it during a fixed period of time. In the meantime, biochemical microorganisms’ activity acting together with plant oxygen supply and interaction and natural filtering by the substrate itself where everything is embedded allow water depuration with contaminant removal from the waste water.
Plant species grown in these green filters are usually emergent macrophytes, such as reed (Phragmites australis), rush (Scirpus lacustris), bulruchs (Typha spp), lilies, and also some floating plants, for instance duckweed plant (Lemna spp) or water hyacinth and in some cases submerged plants. While choosing species, climate adaptation and local conditions of the wetland location should be taken into account.
The importance of spreading the knowledge and fostering the installation of these wetlands lies in its low cost and energy saving when comparing to traditional depuration techniques. These advantages make of this solution a feasible alternative for small municipalities where waste water treatment is not being applied due to the lack of infrastructure investment. Furthermore, these systems have unquestionable environmental advantages such as the contributions to ecosystems preservation providing optimal conditions for wild species survival including the possibility of restoring habitats and species that were lost due to human activities.
CARTIF is currently participating in the project Poctep Aquamundam. This project has the aim of restoring and optimizing a constructed wetlands in Flores de Ávila (Castilla y León, Spain) among other goals. Water from the sewage treatment plant from this small municipality could be reused (for irrigation as an example) and waste water could be back to the riverTrabancos without disturbing the natural ecosystem. Checking the effectiveness of this alternative depuration system will be done following the population of a small fish, the vermillion, a native species from this river and nowadays under a huge stress due to extreme conditions of the river flow during the last years.
For those of us who work in R&D&I in food, the international reference events in the food sector, such as Alimentaria and Hostelco are very interesting. With 4.500 exhibitors from 70 countries and nearly of 150.000 registered experts, Spain has once again turned into the European benchmark of this sector. With a great success of attendance and internationalization, this meeting is not only a good opportunity to generate business, but new trends and bets have been presented for the next years in innovation, gastronomy and restoration.
From the point of view of innovation, we must go through Innoval, where 300 new products and new launches were gathering. For researchers, to find products on the market in which they have been worked on in laboratory is satisfactory. In the case of CARTIF, this year some of our clients were present, such as Cecinas Pablo, with its new range of snacks from beef jerky or Campofrío, with their cured hams with 25% less of salt, the result of a project carried out jointly.
Among the most curious and fun products, the gin-tonic croquettes of Maheso, ready-to-eat calamari sandwich of Pescanova, preserved fish with aloe vera of Vixvital, 3D printed sponge cake of Dulcesol, chocolate pizza of Telepizza, endible straws of Sorbos or the plastic wine glass of One Glass Wine. All of them reflect the importance of R&D&I applied to food to achieve different products that satisfy an increasingly demanding consumer audience.
But, in addition to the most striking and original offers, this edition of Alimentaria has confirmed the trend of recent years: companies seek to offer healthier products, with the reduction of fats, sugars and salt. Pre-cooked dishes, sauces, dairy products, cereal drinks, yoghurts, ‘bio’, ‘with’ and ‘without’ smoothies, sliced for vegetarians (0% meat) or new formulations that include those commonly called ‘superfoods’ (chia, chlorella, spirulina, kale, lucuma, maca…). To this tendency joins the great variety of snacks (meat, vegetables, fruits, legumes or nougat) that are being introduced to the market very quicly.
On the other hand, in the several conferences in the framework of Alimentaria, experiences have been shared in national and international projects, where experts have emphasised the variety of lines of actuation and the strong collaboration between companies and technological centres. This edition underlines the effort of the companies in the development of new products, on the right track of improving their nutritional profiles in their formulations.
The concern of consumers about health in relation to food makes it essential to work on the performance of intervention studies and the preparation of nutritional tests on personalized nutrition in order to establish a diet and health relation focused on the three different large population groups: children, adults and the elderly.
Within this field, in CARTIF we are taking part in large projects such as PRIMICIA, METASIN, PROGRESO or NUTRIPECISIÓN. In all of them, we work to improve the products and adapt the processing conditions to the new formulations in order to satisfy the current regulations and, of course, the needs and requirements set by the consumers.
Food is a trending topic. It is known that a good diet is that which nutrients and food are properly combined, which allows a good state of health.
However, disorders in the diet are currently a real challenge for public health. The growing figures of obesity and diseases related to food in Spain and the rest of Europe, have promoted public administrations related to nutrition and health, develop agreements with the food industry.
Food and Beverage Industry, the first industrial sector of our country, with a turnover of more than 98 M € and with important growth expectations, is now facing new paradigms and challenges in food policy and nutrition.
Thus, new consumer demands and trends in health have promoted the generation of a strategy to improve the composition of food and beverages by the Spanish Ministry of Health through the Spanish Agency of Consumption, Food Security and Nutrition (AECOSAN) with the voluntary commitment of more than twenty sectorial organizations representing 500 companies of the food and beverages sector.
The so-called Collaboration plan for improving the composition of food and beverages and other measures 2017-2020, is aligned with the policy of reformulation promoted by the European Union through several frameworks created within the High Level Group on nutrition and physical activity with Member States, in which food groups and priority sectors were established.
The PLAN includes the reformulation commitments of the Manufacturing and Distribution sectors for more than 3,500 foods and drinks of habitual consumption in children, young people and families in relation to the reduction of added sugars, salt and saturated fats.
Food reformulation consists of improving the content of certain nutrients selected from food without this leading to an increase in energy content or other nutrients, maintaining food safety, flavor and texture so that the product continues to be accepted by consumers. Therefore, this entail a significant investment.
The most noteworthy commitments are, among others, the following measures that will be carried out on 13 food groups in a maximum period of 3 years:
Reduction of added sugars up to 18% in sauces such as ketchup and fried tomato, 10% in dairy products, soft drinks, meat products, breakfast cereals for children and fruit nectars and 5 % in pastries and cakes, cookies, ice cream and special breads
Reduction of saltup to16% in meat products and sauces, up to 13,8% in salty snacks, 10% for ready-to-eat meals and 6,7% in vegetable creams.
Reduction of saturated fats; 10% in the case of for ready-to-eat meals and salty snacks and 5% in pastries, cakes and cookies
This voluntary commitment of the Food Industry to the reformulation of certain foods has been associated with an important effort on innovation for the identification of new raw materials and ingredients, reformulationand production processes in order to achieve food according to sensory specifications and quality that consumers expect, topics in which we have worked intensively in CARTIF with a large number of companies in the sector.
This PLAN also includes agreements with sectors such catering or retail industry, with which commitments have been made to increase the offer healthier menus and meals, with an increase in the offer of dishes that include vegetables, greater presence of lean meats and fish accompanied by garnishes of vegetables, vegetables and/or legumes and to minimize the offer of fried precooked dishes. Meals will be prepared with griddled, baking and oven and sauces or stir-fry dressings will be avoided. Olive oil will be promoted as the best dressing option. Bread will be whole grain and the main dessert option will be seasonal fruit.
Regarding the Modern Restoration or HORECA sector, commitments have been made related to the reduction of the amount of sugar contained in single-dose sachets to 50 % and 33 % in those of salt, as well as the use of low-fat milk in breakfast services.
Finally, vending or automatic distribution sector commits to reduce the maximum amount of sugar added in hot beverages and to increase the number of balanced foods, water and soft drinks without added sugars of the total of products and beverages included in the machine.
With this PLAN, is intended that the different sectors work synergistically to contribute to a more balanced diet with high nutritional quality. The PLAN also wants to promote R & D aimed at creating healthier products, strengthen the collaboration of companies and promote the coordination of these measures with the administrations, as well as impact, from the health and social point of view, the shopping basket and promote good practices to improve the diet from the nutritional point of view. Through all these measures, it is also intended to contribute to improving the scientific base and collect data that drives these initiatives and their monitoring at European level.
These actions, undoubtedly, represent an advance and we will find food products with a composition, in certain nutrients, improved compared to the current ones. However, it is necessary to continue taking steps on behalf of all the actors involved in promoting health and reducing the appearance of food-related diseases by creating new strategies.
