Determination of Poly(lactic acid) Anoxic biodegradability by specific surface area based gas production using wastewater sludge |
| 초록 |
Poly lactic acid is a biobased biodegradable polymer produced as a byproduct from various renewable sources. Monomer lactic acid produced from depolymerized PLA can be used for many industrial applications. The estimation of biodegradability of polymers has been developed. However most of the existing methods require a long term or need harsh conditions such as high temperature and acidic and basic environment. Thus, in this study, we focus on development of feasible testing method and quantitative measurement of biodegradability. The PLA sample with different specific surface area was prepared and anoxic digester sludge was inoculated into each sample. The CO2 and CH4 production were monitored according to time in order to estimate the specific gas production rate based on surface area of polymers. |
