TRANSCRIPT
Saving costs with cooperation
In many cases no essential technical restrictions
hinder LCMW. The strongest factors are financial
costs and safety requirements. The issue of costs
closely relates to the question of available
machinery and technology. Possible solutions can
be seen in cooperation within a region, and
sharing both the machinery and the burden of
initial investment.

• by-product of regular management of
public areas (Figure 1)
• local and renewable energy source
• regional and local actors profit directly from
utilisation
• energy source is in no competition with
food production
…its potential…
Methodology
The starting point for the biomass assessment
carried out in the greenGain project was the
estimation of the theoretical potential, which
based on e.g. statistical databases, samplings,
and yield rates from other projects. However,
theoretical potentials often do not reflect an
accurate and realistic estimation about the
biomass which is feasible to be obtained for
production of energy. Therefore, constraints
causing the theoretical potentials in the seven
model regions not to be fully exploitable were
incorporated in the calculations (Figure 2).
Results
…and how to work with it.
Use by integration
The conversion of the LCMW feedstock to energy
is in many regions of the EU still exceptional,
whereby the most frequent treatment is
composting. The greenGain biomass assessment
showed that LCMW biomass cannot constitute by
itself as a main biomass source. However, it was
observed and confirmed that it can be integrated
in both, local and large-scale supply chains, and
be part of integrated logistical solutions.
About the project
Duration: 01/2015 – 12/2017
Funding: Horizon 2020
Partner countries: ES, IT, DE, CZ
Aim:
Increase energy utilization of
biomass from landscape
conservation and maintenance work
(LCMW) carried out in the public
interest to meet the EU’s demand for
renewable energy.
Biomass:
Woody and herbaceous from
maintenance of urban green areas,
public parks, roadsides, waterways,
hedgerows on banks, ravines,
firewalls, vineyards and olive groves.
Means:
Contribute to identification of
sustainable sources of biomass by
cooperating with regional and local
players to learn more about existing
and implementing new utilization
pathways.

Table 1: Overview of the results compiled in the greenGain biomass assessment.
Sustainable potentials refer to fresh matter only and to a whole NUTS3 area (county or
province). Detailed calculations for the greenGain model regions are described in the
deliverable D5.2, which is available under www.greengain.eu (w= woody and h= herbaceous).

Challenges
• scattered supply & seasonal fluctuation
• low quality: e.g. high bark and ash content,
unfavourable size distribution (Figure 3)
• no clear responsibilities
• no clear legal requirements of waste
management
• little sharing of knowledge and best
practices among professionals & authorities
• insufficient information on amount, type,
location, supply, logistics and energy
demands
