A Better Way
Since 1981, AB has tackled the challenges posed by energy sustainability, working alongside their customers to improve their competitiveness while saving energy and reducing emissions. From their earliest days, they have focused on innovation to develop world-class technologies and processes dedicated to transforming the world of energy.
AB’s objective is to ensure their customers benefit from the best energy sustainability solutions available anywhere.
The AB Group now boasts over 1,000 employees in 20 countries throughout Europe, Russia and North and South America, with primary production and engineering centralized in a state-of-the-art industrial complex located in Orzinuovi, Province of Brescia, Italy.
AB’s customers rely on AB to develop the “Better Way” to support them with the skills, technologies, and processes, so they perform at their best. Together, we are helping build a better world.
AB Strives to be the global reference point for energy sustainability. For AB developing innovation at the service of their customers’ energy means making businesses more sustainable, competitive, and virtuous, reducing consumption, increasing efficiency, and providing customers with advanced technologies and a high-quality service.
Renewable electrical and thermal energy from organic residues.
Biogas is a natural fuel that is obtained through anaerobic digestion, i.e. bacterial fermentation that takes place in the absence of oxygen of organic residues from plant or animal residues.
About 50-70% of the biogas produced is made up of methane and the remainder of carbon dioxide and other minor components. If adequately processed, it can power the internal combustion engine of a cogeneration plant and to produce totally renewable electricity and thermal energy.
A biogas plant consists mainly of two parts: the anaerobic digestion part, where the actual production of biogas takes place (consisting of one or more digestors) and the transformation of biogas into energy part, i.e. the cogeneration plant.
Digestors play a key role in the initial phase of the biogas production process, but the energy efficiency and overall economic performance of the plant depend on the quality and reliability of the technological solutions that make up the cogeneration group.
Benefits of a cogeneration plant:
- Enhancement- Waste materials become a resources, allowing the production of electricity and renewable heat, as well as of digestate, an excellent fertilizer that can be re-used in the agricultural process.
- Sustainability- With a biogas cogeneration plant, respect for the environment is guaranteed thanks to the lack of use of fossil fuels to power the cogeneration plant
- Efficiency Measures- Cogeneration from biogas allows producing programmable energy, which can balance the input of non-programmable renewable sources such as photovoltaic or wind energy
- Integration- The economic advantage guaranteed by biogas cogeneration translates into a substantial saving and into integration of agricultural income.
Technology Strengths, Weaknesses and Critical Indicators
Anaerobic Digester Associated Technology:
NOTE: There are several technology types that are used as part of an integrated manure management system that includes an anaerobic digester and are not applicable to manure management in other cases. The impact of these technologies on the critical indicators are represented as those of an entire anaerobic digester system.
- Long usable life and can be run reliably
- Creates energy and generates environmental credits
- Requires proper preparation of the feedstock
- Requires other technologies for energy utilization
- Requires other technologies for digestate handling
- Proper feeding & system monitoring is required to avoid system downtime
- Proven technology for odor control, GHG reduction and pathogen reduction
AB Energy has recently been added to the Newtrient catalog. Newtrient will continue to work with AB Energy to further refine the cost and performance information on their technologies and services. Newtrient will update this entry as more information becomes available and as new commercial dairy installations come online.
