The farmers are also entitled to the usufructs from fruit trees grown interspersed and along the boundaries of forest plantations. These are marketed locally. For leaf harvests, Perum Perhutani has entered into contracts with 306 farmers. After boiling, the oil passes through separators. Waste leaves are used to fuel the boilers, and for organic manure.
Wastewater is cooled and recycled through the condensers.
The plant runs around the clock, operated by three shifts of workers. Most of the production is sold in the domestic market. The plant employs 67 people. After a decline in indigenous silk production in 1968, due to a market downturn and pebrine disease affecting the silkworms, Perum Perhutani started its sericulture programme in 1974. Species grown at the plantation include Morus alba , M. multicaulis , and M. cathayana .
