AB Facts & Figures


AB was born in 1981 from an idea of the young electro-technical specialist Angelo Baronchelli, still President of the Group.

Angelo Baronchelli, the founder of AB

Born into a family of farmers from Orzinuovi, in the province of Brescia, he has contributed to the family economy since childhood. Thanks to his experience in the family business and his training as an electro-technical expert, he matures the ideas and beliefs that still accompany him today and that gave birth to AB.

The early career as an entrepreneur

Angelo soon joined his father in running the farm, but it was only after his diploma as an electro-technical expert, obtained in Cremona, that he decided to embark on a new path: just 21 years old, in 1981, he starts a business project that follows his entrepreneurial vision.

The birth of AB

In the 1980s, AB built electrical and automation systems for the agricultural and livestock context. In 1996, with the foundation of AB Impianti, the design of ECOMAX® methane and biogas cogeneration system began, integrating all its components into a container.


AB's internationalization process began in 2007, with the opening of the first foreign branch in Spain, in Madrid, which will be followed over the years by the establishment of other companies, up to the current presence in over 20 national markets worldwide, from Europe to North and South America.

The Digital Energy Revolution

In 2018 AB declares its vocation for the future of research and development and innovation with the inauguration of DOABLE, the hub for digitalization. It is one of the first laboratories in the world capable of applying new digital solutions dedicated to energy sustainability. 

Biofuels and treatment of emissions

In 2019, AB launches BIOCH4NGE®, the innovative upgrading system from biogas to biomethane for producing biofuels for the transport sector. In the same year, with the strategic acquisition of a company in the sector, it extends its range of solutions to the sector for the treatment of emissions into the atmosphere.

40 years of AB

In 2021, AB celebrates its fortieth birthday, with over 1,000 employees worldwide. Starting from the experience of a leader in the cogeneration and renewable sources sector, it strengthens its commitment in the field of biofuels and of air emissions treatment, offering itself as a sustainability partner for companies.
