Amritsar: “There is nothing called waste. With the use of scientific know-how and technology, waste can be transformed into wealth,” said Dr Avtar Singh Matharu, a veteran scientist from Green Chemistry Centre of Excellence’ of Chemistry Department, University of York, United Kingdom (UK). He was speaking at Khalsa College on “Transforming waste into wealth’ organised by the Post-graduate Chemistry Department of the college. He dwelt at length as to how such discarded and trashed material, by its re-cycling, could be put to use again. Citing an example of agriculture straw, he explained that how excessive agriculture output could be turned usable by erecting straw blocks by mixing cow dung with it. Dr Matharu reminded that earlier these straw blocks used to be utilised as a bio-alternative of the wood. “Such practice was vogue in the households of the countryside even today and most of the mediocre families make use of it in kitchens,” he asserted.
Dr Matharu also highlighted that the use of discarded paper into microwave conversion and claimed that it produces yellowish oil which possessed excellent adhesive properties. He, however, emphasised upon the use of re-cycling, regenerating and re-using the waste materials so that reserves are preserved which consequently would ensure minimising wastage.
Earlier, Dr M S Batra, head of Chemistry Department, underlined the importance of organising such seminars and inviting experts on the subject like Dr Matharu. He also asserted that with a view to keeping pace with the latest developments in the field of science, such seminars were of paramount importance as they familiarise students as well as the faculty with the new innovations and state-of-the-art technology.
