31. An MoU has been signed up with
BPATC for house hold waste
management

waste to JU waste management plant and
Tk. 5000 for maintenance cost per month.
We will provide a portion of fertilizer on the
ratio of their waste.

32. Another MoU has been signed up with
Arunapolli (JU Housing Society) for house hold
waste management
Arunapolli provides segregated house hold
waste to JU waste management plant and Tk.
13000 for maintenance cost per month.
Two more communities are interested to
provide us their waste and MoU will be signed
up very soon.

33. Reduction of global warming by management of methane
gas.
2000 kg per month organic fertilizer is produced by this
plant which may meet the demand of chemical fertilizer
This model will play a good role in waste management in all
the public university campuses and all the semi urban and
urban region in Bangladesh.
Poverty might be reduced by implemented this plant.
