Recycling and incineration of such materials still remain in problematic as options since it is difficult in sorting plastics for recycling and burning process releases the irritant gases to the environment. Synthesis of biodegradable plastic such as Low-Density Polyethylene-Totally Degradable Plastic Additives (LDP E-, TDPA) plastic polymer becomes a waste management option for polymer in the environment in recent years.\nThe combination of oxidation and biodegradation was considered to evaluate the degradability of LOPE-TOPA plastic. The initial oxidative effect on LDPE-TOPA through microwave: irradiation enhanced its disintegration using a domestic microwave oven of 950W at the frequency of 2.45 GHz and indicated 17.02% decreased value of its tensile strength. The resulted microwave induced plastic was accessible to biodegradation by the activated sludge microorganisms withdrawn from wastewater treatment plant in liquid aerobic environment.\nThe .assessment of biodegradability of 28-day duration recorded that microwave –treated film mineralized 7% while 222% for untreated LDPE-. TDPA ' in; liquid aerobic medium Surface morphological changes and weight losses of biodegraded plastic films showed , the assimilation of activated sludge  microorganisms  based on SEM  analysis. The biodegradation rate could be expressed by a simple first-order product curve and a sigmoidal curve applying iterative of Table Curve window v2.0 software and the reaction rate constants were 9.7 x 10-3 dat-1 for microwave-treated LDPE-TOPA and 9.0 x 10-4~ day-1 for untreated LDPE- TDPA."}]},"item_1583103108160":{"attribute_name":"Keywords","attribute_value_mlt":[{"interim":"LDPE-lDPA"},{"interim":"microwave irradiation"},{"interim":"microorganisms"},{"interim":"biodegradation rate constant"},{"interim":"activated sludge"}]},"item_1583103120197":{"attribute_name":"Files","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2021-01-12"}],"displaytype":"preview","filename":"62.pdf","filesize":[{"value":"4.1 MB"}],"format":"application/pdf","licensetype":"license_0","url":{"url":"https://meral.edu.mm/record/7410/files/62.pdf"},"version_id":"39699692-b7c7-450c-aeda-c8c739496a9c"}]},"item_1583103131163":{"attribute_name":"Journal articles","attribute_value_mlt":[{"subitem_journal_title":"Journal of tThe Myanmar Academy of Arts and Science","subitem_pages":"445-451","subitem_volume":"Vol. VI.
