As data is from a LCA of MDP board production in Brazil, the original numbers had to be converted using the following information: kg of wood produce per seedling = 74.3 and kg of wood consumed to produce 1 m³ of MDP board = 687. ImageURL: https://db3.ecoinvent.org/images/1e2dec14-9883-4f9b-a978-c4b37c33b4cd Polypropylene tubes with substrate are used to the cultivation and it can be reused for 6 to 8 years. However, the consumption of substrate is not included. The production steps are the following: The dataset refers to the production of 1000 Eucalyptus seedling. The dataset contains the production of Eucalyptus seedlings in a tree nursery for plantation in forests. The seedlings are produced in an unheated greenhouse and wood wastes are bought for that. The final product is the seedlings planted in the substrate (as showed in the following picture) inside the polytubes where they are cultivated. Yield capacity is 1.3 million seedlings per month.

RP_PV 731788862.18*0.98/RP 717153.0849364 % The production volume of eucalyptus seedling was estimated from eucalyptus planted area in Brazil (from Brazilian Tree Industry - Report 2017 - http://iba.org/images/shared/Biblioteca/IBA_RelatorioAnual2017.pdf) considering different rotation periods, average density per hectare and mortality rate of planted seedlings). Besides, based on nursery owners and on literature review, it was assumed that 98% of total eucalyptus seedlings production in Brazil is produced in unheated greenhouses.
RP_price_EUR2005 2.8945 % Estimated value. The price of eucalypstus seedling is set to be approximately to 3.5USD. The value is set according to the prices report from the websites parkseed.com (https://parkseed.com/eucalyptus-seeds/p/03179-PK-P1/, accessed 19Feb2018) and seedman.com (https://www.seedman.com/eucalyptus.htm, accessed 19Feb2018).
