A team of four biomedical engineering students with the guidance of a medical incinerator technician designed a chimney filtration system aimed at trapping soot as it is realeased from the medical incinerators durimg the cycles. This came as a response to the soot challenge we identified, first by inspection of the susbtance released from the chimney; black soot as well as through interviewing several individuals inclusive of which are medical doctors. the doctors claimed that the number of patienmts suffering from lung related diseases had begun to increase as compared to the soot. This therefore meant that soot was creating more damage than good; not to mention to the environment as well.

What problem does this idea/product solve or what market need does it serve?

The idea solves the challenge of Soot production from medical waste incinerators; this soot which has been proved harmful to human health as well as dangerous to the environment.

What attributes will make this idea/product successful? Why do you believe that those features will create success?

The gist of the Chimney Filtration System is the double chimney filter made of a fibre glass layer for soot trapping and filtration and two stainless steel layers of varying mesh sizes for effective filtration of all particles. The filter is protected from high temperatures and pressure of the soot by the attachment body that allows for the hot soot to first travel though a distance before interfacing with the filter.Tthe entire system will also be placed not less than 10 feet from the chamber to prevent direct contact with the high temperatures.

Explain how you (your team) will execute to make this idea/product successful? What gives you (your team) an advantage over others already in the market or new to this market?

Currently completely new incinerators are being designed to solve the problem of soot production by tackling poorly designed incinerators. This opportunity however is only made available to health centres and hospitals with alot of capital owing to the expense (greater than USD 14000). This therefore implies that this opportunity is only present to urban health centres and hospitals and not available to the rural health centres and hospitals. The chimney filtration system is therefore designed to solve the problem of soot pollution from medical incinerators in the rural areas. The team is planning to work with those particular hospitals and health centres to develop personalised systems for their medical waste incinerators. This is because no one hospital has the exact same incinerator. This also entails working closely with the incinerator developers such that the idea can be incorporated in their designs.
