The plastic industry is today facing a green revolution; however, biopolymers, produced in low amounts, expensive, and food competitive do not represent an efficient solution. The use of wine waste as second-generation feedstock for the synthesis of polymer building blocks or as reinforcing fillers could represent a solution to reduce biopolymer costs and to boost the biopolymer presence in the market. The present critical review reports the state of the art of the scientific studies concerning the use of wine by-products as substrate for the synthesis of polymer building blocks and as reinforcing fillers for polymers. The review has been mainly focused on the most used bio-based and biodegradable polymers present in the market (i.e., poly(lactic acid), poly(butylene succinate), and poly(hydroxyalkanoates)). The results present in the literature have been reviewed and elaborated in order to suggest new possibilities of development based on the chemical and physical characteristics of wine by-products.

Alexander Parkes found the earliest plastic in 1850. American scientist John Wesley Hyatt achieved the first patent of plastic (1970) and inaugurated the first plastics industry (1873) with his brother in the world. From then on, plastics industry all over the world have experienced about 150 years development. Based on the learning from overseas industries, China gradually constructed and cultivated himself plastics industry system that is full of Chinese characteristics. The amount of plastics production, plastics products and plastics machine production as well as plastics consumption in China increased quickly. The value of plastics import and export trade rose year by year. Nowadays, China reaches an advanced level in the world no matter plastics machine production, plastic goods production, plastics consumption, or outlet of plastics machines and products. Plastic industry has be one of the important light manufacturing pillar industries in society and economics development of China.

Plastics are synthetic or semi-synthetic meltable substances that can be modeled in solid objects. In the modern world, it seems impossible today to live without plastic or synthetic polymers, which production and usage only go back to 1950. While plastics play a central role in modern society, the production of safer and cleaner products for potential use is required for decreasing the negative environmental effects. The purpose of this article is to analyze the plastic industry, the role of plastics in our social life, the situation in the plastics market, plastic recycling, and masterbatch compound production. For the purpose of this article, the main markets which have been analyzed are; Europe, Asia, and North America. There is a specific part focusing on Turkey who ranks 6th in terms of plastics processing capacity in Europe and has a huge plastic waste mismanagement problem. Finally, there is an analysis of the financial and operational side of global plastics trading, contract terms, and payment methods, which are being used today by the companies who are operating in the petrochemical industry and commodity trade financing generally.

As an important metallic powder, aluminum powders are used widely in coating, inks and plastic industry. However, it is necessary to treat the aluminum powders first to improve the properties of weather-resistance, anti-corrosion in acidic or basic media and compatibility with resin. The methods of surface treatment of aluminum powders including encapsulation and using corrosive inhibitors are summarized. The kinds of corrosive inhibitors used in the method of corrosion inhibition and their mechanisms are also reviewed. The processes and technologies of inorganic passivation, encapsulation by polymer absorption and by in situ polymerization are introduced. The research directions of aluminum powders are also presented.
