Using tapes in drip irrigation is associated with environmental problems due to the accumulation of tapes in agricultural areas. Farmers either leave them on the fields or burn them or bury them. All three of these methods pose dangerous environmental hazards. To address this issue, it is recommended that these materials be produced from or with biodegradable materials. In this study, a biodegradable additive was used as a degradation accelerator in the production of tapes. After the production of these tapes, they were used under real conditions and during a growing season and in two treatments: below and on the soil surface, along with a canopy and without shade (beans and radishes). After 6 and 11 months, the tapes were sampled to investigate their degradation. The results showed that tapes made with oxo as an additive began to degrade more quickly than did conventional tapes. A reduction in properties such as weight (p 0.05), Young's modulus (p < 0.05) and toughness (p < 0.05) in tapes produced with oxo additives shows more and faster degradation than conventional tapes. Therefore, the use of oxo master batches in the production of tapes is possible and useful.

In this work, polylactide (PLA) was loaded with wood flour (WF) or hazelnut shells (HSs) (10% and 20% of fillers). The matrix and biocomposites were fully characterized from a mechanical and rheological point of view to test their processability and mechanical performance. Compost burial degradation test (30 days), with or without a prior photo-oxidation step, assessed their biodegradability after an outdoor application, and was monitored by weight loss (WL). The viscosity of the biocomposites was lower than that of the matrix and this unusual result can be attributed to a limited adhesion between the PLA and fillers. Both fillers increased the elastic modulus but decreased the tensile strength and elongation at break. As for the weathering, the degradation of PLA was mostly due to hydrolytic chain scission due to the presence of humidity. Resistance of PLA to UV irradiation improved in presence of both the two fillers. Their lignocellulosic nature was responsible for this behavior. Both fillers induced a high resistance and lower degradation in compost: WL percentages of virgin PLA was about 26%, biocomposites with 20% of WF or HS showed WL of about 10% and 14%, respectively. Photo-oxidation (36 h with condensation cycle) increased the compost degradation rate of both biocomposites and WL of PLA with 20% of WF or HS were about 15% and 21%, respectively, after 30 days.Highlights Poor adhesion between the matrix and fillers reduced the biocomposites viscosity. Fillers increased the elastic modulus but decreased the properties at break. Both fillers improved the resistance of PLA to UV irradiation. Biocomposites showed a lower susceptibility to compost degradation than PLA. Photo-oxidation increased the compost degradation rate of biocomposites.
