The stability of polymers against environmental factors, chemicals, microorganisms, and hydrolysis has challenged society with the accumulation of plastic waste and its management worldwide. Large amounts of plastic litter accumulate in the environment and disintegrate into microplastics (small pieces less than 5 mm in size), a topic of real concern especially for products and applications where the plastics are used for a short time before becoming waste, and where they are difficult to recover after use and remain in the environment. Whether biodegradable polymers can be one of the solutions to the problem of plastic waste is a question very often raised in this context. Although the use of biodegradable polymers appears to be highly promising based on recent and past studies, several aspects need to be considered further regarding environmental sustainability, acceptability, and degradability in the complex natural environment. Intensive efforts need to be invested in developing new environmentally biodegradable polymers and smart mechanisms of degradation after use in the environment. The present viewpoint article discusses the present scenario of the environmental acceptability of biodegradable polymers and the opportunities and challenges they offer regarding solving the problem of microplastics and their impact on the environment.

The change in the properties of low-density polyethylene after adding starch, oxo-material, polylactic acid, and their mixture was studied. Different amounts of the additives were added, and films were prepared by using a twin-screw extruder at 150-225 C. By Minitab software, the optimum percentages of the additives were selected. The films were kept under different environmentalconditions including "open atmosphere," "buried underground," and "buried underground with regular daily irrigation" for 6 months. The degradability, tensile strength, elongation at breaking point, and dart impact were measured. Thermogravimetric analysis and FTIR spectrum changes were used to monitor changes. SEM images illustrated that the starch changed the morphology significantly, while other additives did not show remarkable effects. Mechanical and chemical properties changed significantly when starch was added. The highest changes were recorded for the sample with three additives, which was showing the high efficiency of the film decomposition. The highest amount of chemical changes was recorded for the same film. After 6 months, the lowest crystallinity was recorded by DSC and XRD for the same sample. Different environmental conditions showed different effects on the films mechanical properties. However, chemical properties of the films, excluding the film with starch, did not change significantly.

“…In 2012, plastic mulching films accounted for over 40% of the total plastic films used in agriculture . Mulching is an agricultural practice commonly used for crop production since mid‐1950s . Plastic mulch helps to control weeds and insects, increases soil and air temperature, reduces evaporation, minimizes soil erosion, and prevents soil splashing on fruits or vegetables, as reported by Sintim and Flury …”

The use of flexible films in agriculture has increased intensely in the last 15 years bringing benefits to producers. However, environmental impacts increased due to their incorrect post‐use disposal which leads the degradable films to emerge as an alternative. The production films of poly(butylene adipate‐co‐terephthalate) and poly(lactic acid) reinforced with calcium carbonate (CaCO3) was studied focusing on producing lower cost materials and flexible films. Four different films (reinforcement compositions) were prepared by melt extrusion with 10 and 20 wt % of CaCO3. Mechanical and thermal properties, crystallinity, water absorption, and soil degradation, were evaluated. The addition of reinforcement leads to improved compatibility between the polymers in the matrix, which usually presented phase segregation. The films showed better mechanical properties with the addition of CaCO3. Highly orientated amorphous structures were obtained leading to low water absorption and low degradation in the simulated soil. This low degradation, suggests that the obtained films would be of interest in flexible mulch films manufacturing, particularly for Muridori plantation system, where long‐term plantations are needed. © 2018 Wiley Periodicals, Inc.
