A seminar on ‘effective waste treatment measures' jointly organised by the district chapter of the Institution of Engineers and the Kerala Sastra Sahitya Parishad (KSSP) here on Thursday called upon the city Corporation to take up a public campaign for solid-waste treatment by mobilising the support of all residents' associations, merchant forums, and commercial establishments.

The seminar, which pinpointed the futility of hunting for superior technologies for waste treatment, also urged the Corporation to promote the setting up of maximum number of vermicompost units and biogas plants at households to address the waste management crisis.
