Pune: Pune Municipal Corporation (PMC) has given a positive response to Science and Technology Park’s (STP) proposal to reuse plaster of Paris (PoP) Ganesh idols. The corporation is ready to give land to set up a thermal treatment process of PoP in Warje and Aundh area. The civic body will soon discuss this proposal and would also take a decision about giving financial assistance for this project during the next Standing Committee meeting.
Science Technology Park has given a proposal to the Solid Waste Management Department about reusing PoP with a thermal treatment process. They also wanted financial support and land for the process.
While speaking to Sakal Times, Suresh Jagtap, Head of Solid Waste Management Department, said, “We took detailed information from STP officials. We have decided to provide space to conduct the process of reusing PoP. They need more than 1,500 square metre space for the treatment of PoP. PMC is ready to provide land to STP in Warje and Aundh area. STP wants Rs 15 lakh for the process from the corporation. We will make a proposal and put it before the Standing Committee for approval. The committee will take the final decision of providing money to them.”
According to STP, it is estimated that during Ganesh festival, more than 600 tonnes of PoP is used for such purpose and it causes a lot of water pollution. Generally, the used PoP cannot be put to any useful purpose and hence it poses a problem for waste disposal. While using PoP, a large quantity of water is added to the PoP powder to harden it, which cannot be reused. Hence, STP has developed a systematic process by using specific thermal treatment in which the hardened PoP can be converted into original PoP powder. This PoP can be reused in the same way as the original material. The process can be repeated several times without loss of any mechanical or adhesive properties.
STP proposed that the process should be utilised during the Ganesh festival where a lot of PoP is used to make idols. The process should be supported by the civic body authorities with acceptance of local NGOs and Ganpati mandals.
STP wants to conduct a trial on about 30 tonnes of used PoP and the process can then be suitably scaled up for a plant for treating about 100 tonnes per month. The primary objective of the proposal is to showcase and implement the technology developed by SPPU for better waste management of PoP.
STP wants financial support, space and machinery to conduct the process on a large scale. STP wants PMC to take responsibility for collection and delivery of the collected PoP to the site of recycling.
