Our device can be coupled with the exhaust of diesel engines and can absorb the particulate matter that is being emitted by them. we don’t use a filter and have developed a novel, solvent based method for capturing the particulate matter. this particulate matter keeps collecting in our device and after its concentration reaches a predefined value, we use a patented process of separation of the particulate matter from our device. thus, the product is renewed and its efficiency is maintained. the separated particulate matter goes to our processing facility.  our product has been certified by a lab recognised by ministry of environment and forest, government of india and accredited by national accreditation board for testing & calibration laboratories, department of science and technology, government of india.
