Woody biomass, the most renewable one

Wood, wood chip or pellet: biomass heat production combines saving and energetic efficiency enhancing the most ancient among renewable energies.

Among energy sources contributing to the fight against climate change and meeting the targets aiming to reduce polluting emissions and decarbonisation, the European Union also includes heat production from woody biomass.

The new target set at 32% of heat and electric energy from renewable sources by 2030 is, therefore, more accessible also thanks to this resource available in large quantities, which thanks to technological innovation, pollutes less than fossil sources.

One eco-friendly source, many advantages

Wood biomass heating is convenient for various economic and environmental reasons. This is why it is worth investing in this technology, both for the residential sector and for the industrial or commercial world:

• higher availability in nature, especially on Italian territory;
• enhancement of an otherwise unused resource (e.g. wood processing wastes or pruning);
• programmability to suit the needs of the network, contrary to other renewable energies;
• cost savings compared to diesel or gas;
• government incentives supporting installation;
• significant reduction in energy bills;
• reduction of our Country in dependence on imported fossil fuels.

We often hear about atmospheric pollution caused by cars and heating. The union between technological innovation and renewable sources goes this way.

Does it also apply to woody biomass systems?
By all means, yes, for last generation systems in which emissions from combustion are treated before being released in the atmosphere. Actually, woody biomass releases some noxious elements, but their quantity levels and their toxicity depend on wood quality and the combustion process.

Therefore, technological evolution makes the difference, thanks to systems regulating combustion, filtration and recovery from smokes.

More work with biomass
Heating through biomasses such as forest and agricultural residues and wood processing ones contributes to keeping forests and lands clean and creates new jobs. A positive impact on the employment situation that, especially in rural areas, adds up to less energy dependence from countries producing fossil fuels.

In particular, the economic and social impact of the spreading of biomass systems occurs in three impact levels:

• direct: from design, system construction, life cycle (including maintenance) and number of employees directly employed;
• indirect: created by the supplier sectors up and down the chain (wood chips, carriers, service providers, etc.);
• induced: concerning the virtuous cycle of the national chain which activates new production processes combining supply and demand of renewable energies from woody sources.

The enormous potential of this renewable source will be part of the new edition of BIE – Biomass Innovation Expo (FieraMilano, 17-20 March 2020). Four days of exhibitions, conferences and studies devoted to the entire chain of woody biomass.
