In the long history of human civilization, few materials have so profoundly reshaped our way of life while also prompting deep ecological reflection as plastic. Born in 19th-century laboratories, this synthetic material has, in just 150 years, evolved from "Celluloid"—a substitute for ivory—into everyday items that permeate every corner of modern life, ultimately becoming a serious challenge to our planet's ecosystems. So, who first invented plastic? Let’s trace the timeline and meet the key figures essential to plastic's development.

In modern industrial production, plastic recycling and reuse have become vital for resource sustainability. As a key pre-processing equipment in plastic recycling lines, the squeezer machine plays an essential role in handling film-based materials. Kitech semi-melting type squeezer is expertly designed to dehydrate and dry plastic films after crushing and washing, delivering dry material ready for pelletizing, extrusion, or molding processes. It can operate as a standalone unit or be seamlessly integrated into a complete plastic film recycling washing line.

Virgin plastic is made from basic materials like oil and gas. It goes through a full chemical process to become new, pure plastic that has never been used before. Recycled plastic comes from used plastic items that are collected, processed, and made into plastic again. Because it has been used and reprocessed, it often differs from virgin plastic in several ways. Here’s how you can tell them apart.

In recent decades, the widespread use of plastic products has led to the pervasive presence of microplastics in our environment. A growing body of research confirms that these tiny plastic particles can accumulate within the human body, having been detected in blood, lungs, kidneys, liver, the reproductive system, and even the brain.

Last week, Kitech Machinery celebrated a significant milestone with the successful test run of its KCP180 crushing and pelletizing system. This customized line was developed for a foreign furniture injection molding and recycling manufacturer. The system efficiently processes BOPP film, transforming it into high-quality recycled plastic pellets ready for reuse.

Plastic bags are a ubiquitous part of modern life, but their disposal presents a significant environmental challenge. The two most common endpoints for plastic waste are landfilling and burning plastic. When evaluating which method has a smaller immediate environmental footprint, the scale tips toward landfilling, though neither is a perfect or sustainable solution.

The global push for sustainable plastic recycling is driving significant regulatory updates worldwide. Recently, China, South Korea, and Japan have each announced important new rules for recycled plastics, set to take effect in early 2026. These changes will reshape the industry, requiring businesses to adapt their supply chains and upgrade technologies.

Kitech Machinery's KWPH series shredding and cleaning line mainly consists of an AGR series shredder, an AGH series crusher, a washing tank, a friction washer, a dewatering machine, and a drying and storage system. Large-diameter HDPE pipes are first shredded, then deeply cleaned through the washing tank and friction washer, dewatered by the dewatering machine, and finally dried and stored in the silo system.

China, as the world's largest producer of PET, faces significant hurdles in establishing a robust and high-value plastic recycling ecosystem. While all waste plastic is theoretically recyclable, the reality is a complex web of challenges that ultimately limit the availability of high-grade recycled materials, such as food or cosmetic-grade pellets, within the domestic market. This stands in contrast to developed nations, which successfully produce clear, pure, high-end recycled flakes. The core issues span the entire chain from households to industry and policy.

In today's booming plastic circular economy, efficiency, quality, and cost control are core concerns for recycling companies. Based on years of market experience, Kitech Machinery has launched the KSS series shredder and pelletizing machine—a highly integrated, intelligent, and efficient complete production line. It integrates crushing and granulation, specifically designed for processing complex waste plastics such as plastic scraps, plastic films, raffia, hollow products, and foamed materials. It is your ideal choice for reducing costs, increasing efficiency, and enhancing product competitiveness.

In 2024, global recycled plastic pellet production was approximately 34,613 thousand tons, with an average global market price of approximately $896 per ton. Its applications span packaging, automotive parts, building materials, and consumer goods, driven by both regulatory pressures for the circular economy and increasing corporate commitments to reducing their carbon footprint.

According to the "Plastics Industry Overview 2025" report released by Plastics Europe, global plastics production reached 430.9 million tons in 2024, a year-on-year increase of 4.1%, and an increase of over 16% compared to 2018. Despite regional differences in growth distribution, demand for plastics remains strong, particularly concentrated in the packaging, consumer goods, and automotive industries. However, the global production landscape is undergoing profound changes, with the center of production shifting from Europe and the Americas to Asia, reshaping the global industry landscape.
