Clean energy for Bio-on's new biopolymers "factory" thanks to a trigeneration plant built by Gruppo Hera

Clean energy for Bio-on's new biopolymers "factory" thanks to a trigeneration plant built by Gruppo Hera

Bio-on, the leader in eco-sustainable chemical technologies, and Gruppo Hera, one of Italy's main multi-utility providers, have reached an agreement for the supply of clean energy thanks to the realisation and management of a new technological-energy hub that will house a newly designed trigeneration plant. The deal was signed by Bio-on S.p.A. with Hera Servizi Energia, a subsidiary of Gruppo HERA, and will guarantee clean electric energy for the new plant producing innovative biopolymersthat Bio-on is currently constructing in Castel San Pietro Terme, outside Bologna.

The plant, due to open by the middle of 2018 and begin PHAs bioplastic production thanks to a 15 million Euro investment, will employ approximately 40 people.The plant will occupy an area of 30,000 m², 3,700 of which is covered and 6,000 land for development, and will have a production capacity of 1,000 tons per year expandable to 2,000. It will be equipped with state-of-the-art technologies and the most advanced research laboratories, where Bio-on will test and develop new types of PHAs bioplastic using agricultural and agro-industrial waste as raw material. Bio-on also demonstrates its focus on environmental sustainability in its choice of site, opting to convert a former factory, meaning no new land is wasted.

Through the agreement, Gruppo Hera will supply Bio-on's new plant with a) Power produced and self-consumed, b) Heating in the form of steam, and c) Cooling. The multiannual agreement includes the realisation and maintenance of the entire technological-energy hub associated with the supply of energy, for a total investment from Hera Servizi Energia of 2.4 million Euro.

Hera Servizi Energia is the landmark ESCO in Gruppo Hera's industrial sector, which over the years has developed a portfolio of cogeneration plants built with the best technologies on the market, able to guarantee major energy and economic savings.

The project developed for Bio-on envisages the realisation of the entire technological-energy hub comprising a 1 MW trigeneration power plant, two steam boilers, two high-efficiency industrial coolers and a modern water treatment plant. The energy saving generated is over 800 TOE (tonnes of oil equivalent) per year, equivalent to the amount of CO2 a 320-hectare woodland absorbs in one year or the equivalent of 810 diesel cars being taken off the roads.

"We are extremely proud of this agreement," explains Bio-on S.p.A. Chairman and CEO Marco Astorri, "because it allows us to increase and complete the industrial sustainability of our new production plant. We chose to not use agricultural land by converting a derelict plant, and with HERA we can add strong GREEN credentials in our energy usage to produce a biopolymer like MINERV PHAs that is sustainable and completely biodegradable in nature." Bio-on, a fast-growing company, fundamentally met the objectives of its business plan presented on 22 November 2016 for 2017 and looks to 2018 with major new projects, including its sustainable energy collaboration with HERA.

All the PHAs (polyhydroxyalkanoates) developed by Bio-on are made from renewable plant sources with no competition with food supply chains. They can replace a number of conventional polymers currently made with petrochemical processes using hydrocarbons; they guarantee the same thermo-mechanical properties as conventional plastics with the advantage of being completely eco-sustainable and 100% naturally biodegradable.

The agreement between the two companies has come out of a highly dynamic territory that represents the technological cutting edge in Italy.

"For a company such as ours, which has innovation and sustainability at its foundations,"explained Giorgio Golinelli, managing director of Hera Servizi Energia, "the collaboration with Bio-on is a natural meeting of the minds and a convergence of views that we believe can be developed with an increasing number of players operating in sustainably developing the economy and the territory. With this agreement, thanks to the breadth and quality of our service offering, we can put an additional green stamp on a project that aims to change the world of eco-plastics. Hera has been at the forefront of this sector for some time, encouraging the transition towards a circular economy model that extends the life of raw materials and resources through recycling, reuse and longer-lasting products."

Gruppo Hera

It is one of Italy's largest multi-utility providers working in Environment (waste collection and treatment), Energy (electricity and gas distribution and sale) and Water (waterworks, sewers and purification). The Group employs over 9,000 people and works every day to meet the many and varied needs of over 4.4 million citizens. It serves over 350 local municipalities mainly in the Emilia Romagna, Marche, Tuscany, Abruzzo, Veneto and Friuli Venezia Giulia regions.

Bio-on S.p.A.

Bio-On S.p.A., an Italian Intellectual Property Company (IPC), operates in the bioplastic sector conducting applied research and development of modern bio-fermentation technologies in the field of eco-sustainable and completely naturally biodegradable materials. In particular, Bio-On develops industrial applications through the creation of product characterisations, components and plastic items. Since February 2015, Bio-On S.p.A. has also been operating in the development of natural and sustainable chemicals for the future. Bio-On has developed an exclusive process for the production of a family of polymers called PHAs (polyhydroxyalkanoates) from agricultural waste (including molasses and sugar cane and sugar beet syrups). The bioplastic produced in this way is able to replace the main families of conventional plastics in terms of performance, thermo-mechanical properties and versatility. Bio-On PHAs is a bioplastic that can be classified as 100% natural and completely biodegradable: this has been certified by Vincotte and by USDA (United States Department of Agriculture). the Issuer's strategy envisages the marketing of licenses for PHAs production and related ancillary services, the development of R&D (also through new collaborations with universities, research centres and industrial partners), as well as the realisation of industrial plants designed by Bio-On.

For the seventeenth consecutive year, the company is confirmed among the leading organisations for human resources management, in particular thanks to its distinctive welfare, training and skill development programmes. img_110x150_topemployer2026 (5).jpg centrata The Hera Group has once again been ranked among the best Italian companies for people management and development policies, obtaining the Top Employer certification for the seventeenth year running. This is one of the most prestigious international awards for companies meeting high standards in human resources management. It is awarded by the Netherlands-based Top Employers Institute, a global authority on HR excellence, following a meticulous and increasingly demanding annual audit of specific criteria, including remuneration, working conditions, career opportunities, corporate culture, and the training and development of people. The award recognises the Hera Group’s strategic commitment to continuous learning and organisational wellbeing, in a landscape where career longevity, talent attraction and generational inclusion are increasingly critical. With over 10,500 employees, 96% of whom are employed on permanent contracts, Hera distinguishes itself through an HR model founded on flexible welfare, 360-degree wellbeing, professional growth, the enhancement of uniqueness and a strong cultural identity. Furthermore, the Group’s multi-business nature represents a significant benchmark on the national stage, offering diverse career paths and the opportunity to develop new skills within the same organisation. Among the various national and international awards obtained, the following are worthy of notice: the Diversity & Inclusion Index, compiled by FTSE Russell (a London Stock Exchange Group company), which ranks Hera as the only Italian company in the global Top 10; the Dow Jones Sustainability Index, the prestigious international stock market index that includes listed companies with the best performance across Environmental, Social, and Governance & Economics (ESG) dimensions. Hera has been a member for five years and is included in both the World and European indexes. In addition, the multi-utility has obtained the UNI/PdR 125:2022 gender equality certification, a major recognition involving eleven Group companies, which confirms the commitment to creating an inclusive corporate culture focused on its people. For the Hera Group, continuous training is a cornerstone of its ‘people strategy’: thanks to an annual investment of approximately €15 million, over 97% of employees participate in at least one training initiative, averaging 30 hours per capita. A central role is played by HerAcademy, the Group’s corporate university, which aims to support the energy, environmental, digital and technological transitions through innovative programmes and ongoing dialogue with academia. Longevity is another theme on which the multi-utility is working specifically. With an average employee age of 46.5 years, Hera has moved from having two to four generations coexisting in the workplace. This entails greater complexity but also greater opportunities. The challenge lies in creating an attractive work environment for all generations, stimulating intergenerational dialogue and allowing people of all ages to express their potential, thereby contributing optimally to the achievement of corporate goals. On the welfare front, Hera allocates €23 million annually to its Hextra system, which involves 99% of the workforce. The scheme offers, among other opportunities, initiatives for parenting support, health and pension services, and programmes dedicated to psychological and financial wellbeing. Among the main levers for organisational development, Hera has recently introduced a new leadership model oriented towards purpose and widespread accountability. Employee satisfaction, measured in a recent dedicated survey, and a turnover rate among the lowest in the sector, confirm the solidity of the path the company has taken. In the last three years, the Hera Group has hired over 3,900 people, including insourcing, coupled with growing investments in training, process digitisation and the development of skills geared towards sustainability and circularity. Recruitment is expected to remain at these levels for the coming years. «Our corporate purpose is rooted in a broader conviction: that the appreciation and satisfaction of the people who work in our Group are essential to ensuring the growth and solidity of the company and, at the same time, to providing increasingly better services, with positive environmental and economic impacts for the areas we serve», said Cristian Fabbri, Executive Chairman of the Hera Group. «The pillars of the Good Work Deal are fully aligned with our purpose: health and safety; integrated supply chains and tenders; equity and inclusion; wellbeing, professional development and productivity; sustainability and shared value. Within these areas, we make concrete commitments, keeping the people of the Hera Group firmly at the centre. Our model aims to be a bridge to the future, responding effectively to the ongoing evolutions in the labour market through a just transition, where all stakeholders participate in creating sustainable development and benefit from this growth». In 2026, the Top Employers Institute certified nearly 2,500 organisations, including the Hera Group, across 131 countries/regions. These certified companies have a positive impact on the lives of over 14 million employees worldwide. Adrian Seligman, CEO of the Top Employers Institute, commented: «The achievement of the Top Employer certification for 2026 reflects the Hera Group's commitment to creating an outstanding work environment that enables lasting business performance. Its strong alignment between personnel strategy and organisational goals, combined with a commitment to continuous improvement, demonstrates the impact of its transformative practices. We are proud to reward the Hera Group for its significant contribution to a better world of work in Italy». 2026-01-15 img_110x150_topemployer2026 (4).jpg
