Burning the Documents
        Burning the papers is likewise regarded as a reliable method of getting rid of documents as it makes sure that the
        documents that are burnt can never be reconstructed or read again. Although this method is not always practical,
        it is beneficial many a times when no other means of discarding are conveniently available. In terms of pollution,
        this approach is not advised.

        Incineration
        Incineration is a method of treating waste which involves burning the organic compounds found in waste products.
        The same can be used for paper and plastic-based materials. The solid mass of the original waste is reduced
        by around 80 to 85%, while the volume is reduced by around 95 and 96%. During burning of waste, however,
        pollutants are created. However, there are other pollution-free incinerators available.





                Recap



           • Data  governance  framework  aims at  creating  methods, set of responsibilities  and  processes to standardise, integrate,
           protect and store data.
           • The private data acquired from a person with their consent should never be exposed for use by different businesses or
           individuals.
           • The end goal of all customer data collection should be to provide an enhanced customer experience that makes customers
           want to share their data.
           • Perhaps one of the biggest, most complex, and controversial issues regarding data ethics is how individual’s data may
           create unfair bias.
           • Once you are done with the user data, especially confidential data, it is important that you discard this data in appropriate
           way to make sure that it is not accessed by any unauthorised person and it is not misused in anyway.
           • Shredding is a great way to destroy data if you have a large data enterprise centre or a large stockpile of old media that
           you want to destroy.
