In today’s world plastic is a part of everyone’s life. According to American Chemistry Council primary data source, plastics generation was 35.4 million tons in 2017 in the United States, which was about 13.2 percent of total Municipal Solid Waste generation. Plastics makes thousands of products that add convenience, comfort and safety. Due to its light weight, strength and easily mouldable ability it is used as an ideal packaging material. It is also used in many sports to increase athlete efficiency and safety. It increases the efficiency and hygiene of medicines. It is also used in making surgical instruments. Inspite of its many advantages one of the biggest disadvantage is, it will take 1000 years to decompose in Landfills. When it burns, it produces toxic gases which adds to environmental pollution. Plastics, when it dumped in water bodies it threats aquatic life. Plastic does not allow the rainwater to seep into the ground. However, the plastic bags negatively affects environment and human health. 18 states have banned single-use plastic bags such as Maharashtra, Tamil Nadu and Madhya Pradesh. In most of the countries, bags of thickness of less than 50 microns are banned. In order to study the awareness about single use plastic ban in Nagpur City, we conducted survey of some Hotels, Restaurants, Vegetable markets and Grocery

The purpose of the paper is the description of the main applications of the so-called “Green Composites”, composed by natural fibers, such as hemp and flax, embedded by bio-polymers and the contribution of such materials to the reduction of the environmental pollution. Since the Kyoto Conference at the end of 90’s of the last century, there is higher and higher attention to the concepts of sustainability. The market of composite materials based on synthetic resins and synthetic fibers, such as glass and carbon fibers, is huge. Billions of tons worldwide are used in the fields of civil constructions, marine constructions, sport goods, automotive, aerospace constructions. After a short description of the most interesting bio-polymers and natural fibers of interest worldwide, the paper describes the products developed nowadays and future possibilities for more applications, with care to future applications in aeronautical constructions.
