Hitachi Zosen (Hitz)Hitz logo

Hitachi Zosen is a Japanese company with over 130 years of history and has a wide range of business domains; Environment/Green Energy and Social Infrastructure & Disaster Prevention. Hitachi Zosen group has designed, constructed and operated a number of municipal waste treatment plants combined with energy production all over the world.

Hitachi Zosen has developed a pyrolysis system able to handle livestock slurry. This is based on a rotating kiln using the heat of the exhaust gases of the pyrolysis process. Therefore once it starts, the process is self-sustaining and requires no external energy input. This makes it cost effective and potentially attractive for treating large quantities of livestock slurry (around 100 000 tonnes/year). From livestock slurry rich in phosphorous, a biochar with agriculturally effective content of phosphorous is produced. Japan, like Europe, depends on imported phosphorous for phosphate fertilizer, and this has caused Hitachi Zosen to develop the pyrolysis process.

A pilot plant has been operating in Japan and Hitachi Zosen sees the EU as a potential market for its pyrolysis systems. The company considers that the revision of the Fertiliser Regulation has the potential to open up a pan-European market for phosphorous-rich biochar and in turn demand for biochar production systems. Hitachi Zosen’s membership of ESPP will enable the company to take an active role in collective action on both the EU Fertilisers Regulation proposal and in other legislative areas, such as REACH registration.
