Opis:
Plastic is a source of pollution both on land and sea that can disrupt balance of the ecosystem. The characteristic of plastic as a material is difficult to decompose causing problems for environment. Various research needed to produce bioplastics that easily biodegradable in about 60 days. Biodegradable plastics are made from organic materials in the form of starch. Durian seed starch is one of the potential raw materials that can be used as bioplastics. Durian fruit is one of the typical fruits in Indonesia, at present seeds of durian had not been used as raw materials to produce object with economic values. It is necessary to combine the processing of durian seeds through a recovery approach in the form of processing into bioplastics. The aim of study is to analyze the effect of adding PEG 400 as a plasticizer plus calcium carbonate as a solidifier. Tests were carried out on swelling ability, acid and base resistance, tensile strength and biodegradation. The variation of the addition of PEG 400 is 4%; 30%; 50% and 70% were carried out to analyze the effect of different concentrations of plasticizers. None of the tensile test results met SNI 7188-11:2018 but all variations had biodegradation values according to SNI 7188-11:2018. Swelling test resulted from 4% and 30% are 1.2% and 2.1% respectively.

Opis:
According to Directive (EU) 2019/904 of the European Parliament and of the Council of 5 June 2019, single-use plastic cutlery, cotton buds, straws and stirrers will be banned in the member states of EU from summer 2021 onwards. Many of them are being replaced by compostable products. The aim of the research was to assess the biological disintegration of selected single-use products under real conditions of urban composting facility. All tested products are established for the Slovak market as 100% compostable by a composting facility. The eight selected products from five different producers were placed into a composting pile of the urban composting facility for 12 weeks. The samples were visually inspected on a regular basis. Temperature and humidity of the pile were continuously measured at the same time. Three samples from each kind of tested product were analyzed, 3 pieces of filter paper were used as the reference samples. The research showed that all tested products were completely or partially disintegrated during the considered period. The average degree of the disintegration of 90% was not reached for one producer only.
