Further studies could be done on the secondary metabolite contents of the pulp in order to plan the phytochemical production forward without throwing away any sidestreams of the production. The translocation of metals speficially into inflorescence is not addressed in current research. The difference of the soil types in heavy metal accumulation is something to clarify as well, for sustainable cultivation protocol for reduced amount of heavy metals in the biomass and most amount of biomass used. Different secondary metabolite contents and processing methods of the pulp, which could be extracted with ethanol for example could be studied for the maximal usage of biomass.

Remarks

This paper is a result of the authors own business and studies at the University of Helsinki
I want to thank my professor Frederick Stoddard for guiding and giving feedback
