      abstract     = {Aim and approach used: Miscanthus (ANDERSSON) is a
                      promising perennial industrial crop whose biomass can be
                      used for both bioenergy and biobased products. In view of
                      increasing land use conflicts between food crop cultivation,
                      nature conservation and urbanization, it is a positive
                      aspect that the cultivation of Miscanthus can be carried out
                      on so-called marginal agricultural areas. However,
                      Miscanthus inflorescences do not provide nectar or pollen,
                      so diversification measures are required to increase the
                      biodiversity supporting ecosystem services of
                      Miscanthus-dominated regions. The co-cultivation of
                      perennial flower-rich wild plant species (WPS) could
                      function as biodiversity hotspots in these regions.
                      Furthermore, Miscanthus and the WPS biomass have already
                      showed high suitability for combustion. However, it is still
                      unknown how a substrate mix of Miscanthus and WPS performs
                      qualitatively. This study assesses the effects of mixing the
                      biomass from WPS and Miscanthus on the calorific value and
                      the overall combustion characteristics. Plant material from
                      a long-term field trial in Southwest Germany was used for
                      analyzing both higher heating value, ash melting behavior,
                      lignocellulosic composition and relevant macro and trace
                      elements. The biomass yield was not considered in this
                      study.Scientific innovation and relevance: The innovation of
                      this study lies within the concept of improving the overall
                      ecosystem service performance of Miscanthus cultivation at
                      farm scale, especially with regard to biodiversity
                      friendliness, through agricultural diversification. The
                      results are relevant because they show the possibility to
                      improve both ecosystem services and biomass quality by
                      combining different types of plant biomasses. This will
                      demonstrate the potential synergies between ecosystem
                      services and economic feasibility in biomass production.
                      Results and conclusions: As expected, the addition of WPS
                      biomass did not affect the calorific value of Miscanthus
                      biomass, but it improved the overall combustion
                      characteristics of Miscanthus biomass. The latter was
                      indicated by both an improved ash melting behavior and an
                      increase of the calculated critical temperature (when
                      $100\%$ of ash is molten). For example, the addition of
                      $30\%$ common tansy (Tanacetum vulgare L.) dry matter
                      biomass to Miscanthus dry matter biomass resulted in an
                      increase of the critical temperature from 1000 °C to 1200
                      °C. These results indicate that the addition of biomass
                      from WPS like common tansy could reduce maintenance costs of
                      incineration plants and thus compensate for lower biomass
                      yield levels compared with Miscanthus. Consequently, this
                      study provides an example for how to improve overall
                      ecosystem services of biomass production at farm scale
                      without impeding economic feasibility, and thereby
                      contributing to the development of a sustainable
                      bioeconomy.},
