So Weyland is collecting something that has been named by scientists in this fictional future as Eitr, referencing a mythological poison that is produced by a serpent and is the very first spark of life. This ties into so many of the themes that have been showing up in this film. Serpents, poisons/acids, creation myths, Loki/Prometheus.
The question is how did they get it if the Prometheus Project has not yet launched? The page mentions that Weyland has received message from deep space, so maybe these messages contain instructions on how to formulate it?
