Galileo’s Eye, a sustainability tool based on the Exergy approach

Exergy Ltd and Solberg Eng. have been working together for the past three years in the development of the sustainability rating tool

Exergy Ltd and Solberg Eng. have been working together for the past two years in the development and testing of the successful Galileo’s Eye methodology. The exergy-based technology allows optimising the use of the resources such as energy, water, and materials. In comparison to the Energy Efficiency rating, the Exergy Efficiency also consider environmental, economic and social indicators. Exergy Efficiency measures the quantity and also the quality of energy consumed.


“We have developed interesting ideas and projects together around the exergy methodology. Now, we think it is time to strengthen the efforts with the ultimate goal of empowering businesses and communities to achieve their sustainability goals”, said Fernando Centeno, Exergy Ltd.


Proven Methodology

The methodology has already proven its effectiveness. More than 73% savings in water use and 39% savings in fossil use were achieved in a group of facilities in Minnesota, USA. In Colombia, the methodology was also applied in the waste treatment facilities of the Medellin City. Feasible strategies for waste management in the city were proposed and if implemented the system can increase its Exergy Efficiency by 39% compared to the current scenario. In Europe, Galileo’s Eye is being applied in various scenarios and projects that aim to reduce the environmental impact and improve the use of scarce resources.


“The Global situation is demanding more innovative and efficient solutions to face the challenge of the climate change,” said Dave Solberg. In the USA, for example, the American College & University Presidents Climate Commitment (ACUPCC), with over 650 school members, is thriving to take immediate actions to reduce greenhouse emissions and go climate neutral. This is a clear evidence of the growing need for integrated technologies that can effectively help them fulfil their commitment.
The Collaborative Mission was constituted in January 2017 offering specialized services for the North American Market.

Exergy present feasible and cost-effective solutions to produce bioelectricity through microbial fuel cells

Exergy participates in the Agrocycle project which is addressing a wide range of valorisation pathways for agriculture using a circular economy approach, including bio-fuels, high value-added biopolymers, wastewater treatment and microbial fuel cells, among others.

For this project, Exergy is in charge of the demonstration of the technical feasibility of the pyrolysis of forestry residues and the production of bioelectricity by means of Microbial Fuel Cells (MFC), as well as leading the overall biofuels’ production activity where biobutanol, bioethanol, and biogas are also produced.

At the month 18 General Assembly meeting held in Brussels on October 18th, Rocio Roldan and Sara Monasterio, from the Sustainable Processes Department at Exergy, presented the general overview of the actions carried out in terms of biofuels’ production. The MFC activity progress was presented and compared with related activities developed in parallel in Nanjing Uni in China. Exergy showed a feasible and cost-effective solution which has been engineered and designed to produce electricity at a small scale from wastewater treatment activities related to the agri-food waste processing sector.
The MFC results, according to the consortium, “seem to be promising considering the narrow timeframe of the Agrocycle project.”
During the same week, the Agri-Food Waste Day Conference was held on October 17th in Brussels. The conference was a joint initiative between the European projects Agrocycle and No AgroWaste, both of them funded under the same topic Waste-7-2015, with the aim to present current thinking and developments in relation to the Circular Economy applied across the agri-food industry. Different technologies and approaches were presented for the valorisation of agri-food waste in high-value intermediate and final products: biogas, digestate, biomethane, biohythane, bio-oil, bioethanol, biobutanol, syngas, bio-oil, bioethanol, biochar, building blocks, biopolymers, lignocell filters, composites and other chemicals, biofertilisers, nutraceutical, pharma products, wastewater technologies, animal feedstock and bioenergy, where some of them are common in both projects addressed by different technologies. The conference also had a strong focus on the business opportunities around the technologies. A wide range of different stakeholders and organisations both internal and external participated in the event including partners from China and Taiwan.

Exergy Analysis to prove the efficiency of Shallow Geothermal systems and Underground Thermal Storage

Shallow geothermal energy systems (SGES) are a stable, reliable and renewable energy source with some key features compared to many other resources. However, its implementation at large scale presents some challenges, considering the high upfront capital needed compared to other solutions such as gas or other fossil technologies, the low awareness, and the diverse and changing regulations.
GEOCOND will overcome these challenges with a particular focus on capital cost reduction, increased efficiency, increased reliability & security, extended lifespan, improved environmental compatibility and increased awareness by exploiting the high potential offered by a unique combination of focused, system-wide engineering as well as new materials and technologies in the key areas of SGES and UTES.
By a smart combination of different material solutions under the umbrella of sophisticated engineering, optimization, testing and on-site validation, GEOCOND will develop solutions to increase the thermal performance of the different subsystems configuring an SGES or UTES. Cost reductions of around 25% overall will allow SGES/UTES solutions to substantially gain competitiveness in the market.
Exergy will contribute to this project by performing its Exergy Analysis and Energy Audit and the socio-economic and environmental impact assessments based on our proprietary Galileo’s Eye Methodology. Exergy also leads the Dissemination, Communication, and Exploitation Work Package especially focusing on the exploitation approach.
The project is coordinated by the Universitat Politecnica de Valencia in collaboration with 9 partners from 8 different countries (AIMPLAS-Spain; EXTRULINE SYSTEMS S.L-Spain; CBI Betonginstitutet AB-Sweden; Sabanci University-Turkey; Çimsa Çimento Sanayi AŞ-Turkey; SILMA SR- Italy; CARMEL OLEFINS LIMITED-Israel;  UBeG-Germany; and EXERGY LTD- UK).
This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement Nº 727583.

Introducing PERCAL, From MSW to High Valued Chemical Products

PERCAL is a European Project that focuses on the valorisation of the greatest potential of carbohydrates, proteins, and lipids from the organic fractions of municipal solid waste (MSW). Through PERCAL, 85% of carbohydrates will be converted into fermentable sugars and subsequently transformed into marketable products. Additionally, PERCAL aims to treat 600 g/kg of the dry fractions of MSW found in biochemical products. This is more than double the amount currently treated by the PERSEO technology and other similar technologies available at pilot plant scale.
The intermediate chemical bioproducts, as a result of PERCAL, are expected to gain huge industrial interest (bioethanol, lactic acid, succinic acid). These products will be used as chemical building blocks to manufacture eco-friendly ethyl lactate, hot melt adhesives, biopolyester-polyols for the production of polyurethanes, as well as for the fabrication of biosurfactants from lipid and protein remaining fraction of biowaste.


The project is coordinated by IMECAL and has received funding from the Bio Based Industries Joint Undertaking under the European Union’s Horizon 2020 research and innovation programme under grant agreement No 745828. With a budget of 3.4 M€ and 3 years of duration.
On July 4th and 5th, the project celebrated its kick-off meeting. The consortium is built of 12 organisations: IMECAL, AIMPLAS and CENER (Spain), Agricultural University of Athens (Greece),  ATB Potsdam and Covestro (Germany), Ghent University (Belgium), TBW Research (Austria), VISUM (Ireland), SOFTER Group (Italy), Hayat Kimya (Turkey) and Exergy (United Kingdom).

Turning Waste into new, useful, bio-products. Exergy are proud to be part of the innovative URBIOFIN project.

The URBIOFIN project (“Demonstration of an integrated innovative biorefinery for the transformation of Municipal Solid Waste (MSW) into new BioBased products”) has officially started. On June 12th and 13th, IMECAL hosted the kick-off meeting of the innovative URBIOFIN project. The meeting began with an introduction of all the partners and WPs as well the short and long-term actions of the project. During the first day of the meeting, partners were privileged to be given a tour of the IMECAL Perseo® Plant (L’Alcudia, Spain). They were able to see the different equipment involved in the process of bioethanol production from the organic fraction of Municipal Solid Waste (MSW), as well as the laboratories and the control system. A networking visit across the City of Arts and Sciences (Valencia) was also developed with networking purposes before holding the official project dinner.
The project is coordinated by IMECAL (Spain) and has received funding from H2020-EU Bio-based Industries Joint Technology Initiative (BBI-JTI) – Project budget €15M, granted €10.9M. The objective of the innovative URBIOFIN project is to demonstrate the techno-economic and environmental viability of the conversion of the organic fraction of MSW into bioproducts (bioethanol, biochemicals, bioplastics and additives) with a high industrial interest. The URBIOFIN Consortium is composed of 16 entities: IMECAL, AINIA, CIEMAT, URBASER, IRIAF, Biomasa Peninsular, University of Valladolid (Spain), Novozymes (Denmark), GI Dynamics and Wageningen University & Research (Netherlands), VISUM (Ireland), NaturePlast, SES (France), Exergy (UK) and NATRUE (Belgium) and Bio-economy Cluster (Germany).
Exergy Ltd is leading the integration of the new Urban Biorefinery approach, along with the different economic, social and environmental analysis to demonstrate the sustainability of the new solutions. During these four years of the project lifecycle, Exergy will be in charge of integrating the three production modules (based in three Spanish locations: L’Alcudia (IMECAL), Zaragoza (Urbaser) and Puertollano (IRIAF-Clamber plant)) and optimise the parameters for a virtual up-scaling of the whole process. Different analysis will be developed in parallel from the information gathered throughout the project.
“There is a huge generation of municipal solid waste in a global context nowadays. According to EU statistics, an average of 477 kg of municipal solid waste per person is generated in the EU28, where a high content of organic fraction is found (circa 50%). Currently, the most sustainable solution to treat these organic fractions contained in the MSW, include composting and anaerobic digestion, however a great fraction is still incinerated or landfilled. URBIOFIN proposes a new urban biorefinery approach to obtain a range of high-value products from the organic fractions of the MSW (after sorting of recyclable components and removal of inerts) which includes the production of bioethylene from bioethanol. Ethylene is an important industrial building block which is mainly made from fossil sources, polyhydroxyalkanoates (PHA) for bioplastic production, biofertilisers (liquid and solid), biogas and biomethane as chemical building block. This approach is in alignment with the Circular Economy Package plan of the EC and the Waste Directive, aiming the project at a zero-waste fraction (after a previous pre-sorting of other fractions from the organic one) and a complete valorisation into potential industrial interest in bio based products. From Exergy, it is a privilege to be part of this demonstration action as it will make us pioneers in the modelling of biorefineries from urban wastes. It is going to be an exciting 4 year challenge for us and our 15 project partners!” – Says Rocio Roldan, Chemical Engineer at Exergy Ltd and work package leader in the integration of the urban biorefinery. “This project has received funding from the Bio Based Industries Joint Undertaking under the European Union’s Horizon 2020 research and innovation programme under grant agreement No 745785”.
