The limited degradation of synthetic polymers used in food packaging when discarded in the environment is a major concern for society. Therefore, industry and academia have sought to develop biodegradable and eco-friendly materials for single-use in packaging. An interesting alternative for the food industry is biodegradable polymeric films, which is why different biopolymers have been used in the production of sustainable packaging. It is worth mentioning that the use of biodegradable polymers is one of the most successful innovations in the industry to address issues related to the environment. Among the available raw materials, starch extracted from different renewable sources is very promising for this purpose, due to its abundance, low-cost compared to other polymers and ability to produce non-toxic films. However, when used alone, pure starch has many limitations, which can be overcome by developing a mixture with other polymers (polymer blends), preferably from renewable and biodegradable sources, such as poly(lactic acid) (PLA). In this context, the absence of literature reviews evidencing the results of the application of films in foods led us to write this article, given the importance of polymer blends produced with different types of starch (cassava, corn, pea, potato, rice and wheat) and the PLA matrix. According to the results, it is clear that polymer blends based on PLA/Starch for food packaging are very promising, already being part of the industries solutions, aiming to minimize the large volume of plastic waste of petrochemical origin discarded in nature. Obviously, as with any technology, more research is needed to further improve the performance of the films, and while much research has made great strides, there are still limitations that prevent the commercialization of these materials.

The over irrigation method applies to meet crop demand may not be a sustainable approach in the near future. Considering agricultural water demand constitutes a huge water consumption than the portable demand, alternative to the over-irrigation practice could be explored as over-irrigation could lead to water wastage and groundwater pollution. The current study investigates the Perlis state soil by determining the minimal water storage in the soil to maintain crop water demand. All the soil series in the state were identified and classified into soil texture based on its sand, silt, and clay composition. The soil water characteristic curve was determined to relate the soil water content to soil particle suction pressure, which then used to determine the soil water content field capacity and permanent wilting point. Subsequently, the plant available water can be determined. The Chengai, Kangar, Hutan, Sogomana, Gajah Mati, Kundor, and Tualang soil series constitute the highest plant available so that it could store more water for crop usage than the other soil series. The study concludes that crop irrigation at field capacity was necessary to avoid water wastage than irrigation at fully saturated soil water content.

“…Over-irrigation on crop fields by farmers protected the high-value crop over a relatively cheap water supply. Additionally, over-irrigation potential in water ponding [6] on soil surface increases water evaporation, and deeper water penetration to the soil contributes to groundwater resources [7]. Moreover, over-irrigation could lead to landslide, especially in the sloppy area [8].…”

Water is a limited resource for Perlis state. Domestically, meeting the water supply in the state requires improving the current supply facility and repairing water leakages in the supply system. However, an even more important aspect of water resources management is the water consumption from agricultural activities such as the over-irrigation in the crop field. This study identifies the soil series of Perlis state, determines its soil textures, estimates the field capacity, permanent wilting point, and plant available water. Additionally, the water infiltration studies were carried out. Results showed there were ten soil series present in the state, and this soil can be categorized by four soil textures that the clay soil texture dominates in seven soil series. Fully saturated soil in the Perlis state potentially losses 27-56% of its soil moisture content drains by gravity, which is unavailable to crop consumption, hence, wastage. An estimated 1.7 x 10-4 to 2.1 x 10-3 m/s water infiltration rate over the soil depths from 0.15-1.5 m. Knowing the soil surface area for the crop field allows the estimate of water volume needed in a unit time needed for storage tank estimation and distribution system designs. The water requirement increases by including the water evaporation rate into the water infiltration rate.
