In the discussion after this paper presentation, several people pointed out that making compost into pellets is
still a relatively new technology in Japan, and asked if the technology could be transferred to other countries.
In particular, there was concern about the production costs. Dr. Hara explained that the production costs
depend on the volume of the output, but are generally 3-15 Yen (US$ 0.03) per kilogram at the farm level.
The throughput each day for an average on-farm operation is around 1.5 mt of compost, which makes about
one mt of pellets. An operation of this kind in Japan could expect to have the following production costs.
