The Biomass Centre is organised as GmbH & Co. KG. It has been financed in public-private partnership. During the foundation of the Biomass Centre an action plan on how to reach the energy self-supply in the Achental valley til 2020 was worked out. Based on the Biomass Centre and the Ökomodell Achental a lot of acitvities are ongoing, many national and international projects are implemented. In the activites bottom-up and top-down criteria are regarded and governance models are very important.

The Biomass Centre contributes to the energy supply from the region for the region in the Achental valley. The Centre also points out and realises new ways in reaching the energy self-supply. A couple of innovative ideas have been and will be implemented. These activities contribute to a higher regional added value, knowledge and experience are shared. Target groups are regional craft enterprises, house owners, experts as well as visitors from all over the world. Different national and international EU projects are in charge of the staff at the Biomass Centre.


Having been project partner in the EU Project "Res-Integration" (2004-2007) was the basis for the activities in the energy sector in the Achental valley. In a study "Renewable energies for the Achental and the Leukental" both the potentials for the use of local, renewable energies in the valley as well as the possibilities of establishing the valley as a model region for renewable energies in a rural area were examined. Since the results were positive, a Biomass Centre with a car pool was built up and long-ranging trade-connections were established. In 2008 a "Regional development concept for the Bioenergy-Region Achental" was published. In 2009 the Achental valley became one of 25 winners in the competition "Bioenergy-Regions" of the German Federal Ministry of Food, Agriculture and Consumer Protection.


Today there exists the Biomass-Centre with around 10 new jobs in full- and part-time. Furthermore a local heating supply for Grassau was built up in connection to the Biomass Centre. In 2012 a heatpipe reformer was inaugurated. Different national and EU-projects are in charge of the staff at the Biomass Centre. A follow-up application and project as German Bioenergy-Region is planned in 2012. Related to this project a couple of so called "Gipfelprojekte" were implemented, e.g. a decentralised biogas plant, a local heating supply for one more Achental municipality or the realisation of short-rotation plantations.

II Assessment criteria

Mitigation effects: Very high

Through the Biomass Centre and the local heating supply for Grassau 70.402 t CO2 have been saved in the last years. With help of the heatpipe reformer additionally 2.016 t CO2 will be saved per year. By now 33 Mio l fuel have been saved.

Impacts on adaptation: Neutral

Since for the activities timber is needed, it must be ensured that the local and regional forests are managed in a sustainable way.

Impacts on environment:

- Landscape: Neutral
- Alpine ecosystems / biodiversity: Neutral
- Water / soil / air: Very positive
- "Other": None

Extending the use of renewable energies and saving CO2 actions have positive influences on the environment and water, soil, air.

Impacts on society:

- Social justice: Neutral
- Regional / cultural identity: Very positive
- "Other": None

The Achental valley is a popular destination for energy issues. Visitors and experts come to the valley for getting informed about innovative ideas and measures in the field of bioenergy.

Impacts on economy:

- Employment / job creation: Very positive
- Added value / income: Positive
- Know how / competitiveness: Positive
- "Other": None

By now around 12 Mio Euro have been invested in the Biomass Centre, the local heating supply and the heatpipe reformer. Ten jobs, part- and full-time, have been created.

Public relations impact and awareness-raising: Very high

The Biomass Centre organises public "Bioenergy Days" (with around 3.500 visitors). Interested people and experts from different countries come to the Achental for getting information about the activities in the field of energy and in general about sustainable regional development (in the last years around 1500 visitors). Many people more were informed by newspapers, radio or tv.

Transferability: Very high

There are quite good ways to establish the use of biomass or to implement further Achental examples in other regions, independent of the size of the region. The demand for renewable energies is going to increase.

Cross sectoral and integrative approach: High

The main focus of the Biomasse Centre is to produce bioenergy for the Achental valley. These activities are extended on innovative ideas like the implementation of a heatpipe reformer. Additionally the Biomass Centre gives impulses for using further renewable energy sources in the region. For example it is planned to examine how to use the water power in the Tiroler Achen regarding ecological, technic and economic issues.

Good governance: Very high

Since the Biomass Centre is established in a public-private partnership different target groups are involved in the development of the biomass and renewable energy sector. Since there are close connections to the Ökomodell Achental the mayors of the nine Achental municipalties are closely involved in the activities.
