Technical Evolution, Industrial Dynamics and Strategic Factors in Polymer Recycling within the Global Context
Essay. Recycling of Post-Consumer Plastics. Chapter 1: The Global Plastic Recycling System
The global plastic recycling system is a complex, multilayered industrial structure in continuous transformation. It reflects not only the evolution of manufacturing technologies but also the economic, social and regulatory tensions that define our era.
It is a sector that has had to reinvent itself repeatedly, dealing with a material—plastic—that is both essential to the modern economy and problematic due to its environmental impact. Today, recycling is no longer a secondary activity within waste-management systems: it has become a cornerstone of the circular economy, a strategic arena for industrial competitiveness, and a concrete response to sustainability requirements from governments, businesses and citizens.
To fully understand the scale of this phenomenon, it is necessary to retrace its historical evolution, examine in detail the dynamics of the waste cycle, clearly define the technical differences between post-consumer and post-industrial streams, and analyse the drivers that are reshaping the rules of the sector.
Historical Evolution of the Sector
The history of plastic recycling begins long before sustainability became a global concern. In the 1950s and 1960s, when plastics began to spread on a massive scale, the industrial philosophy was entirely linear: produce, use, dispose. Polymers were seen as revolutionary materials—cheap, lightweight, versatile—and the priority was to develop new applications, not to close production loops. Recycling was therefore occasional and almost entirely limited to industrial waste—trimmings, off-spec granules, moulding residues—that some companies reintroduced into production purely for economic reasons.
A first shift took place in the 1970s.
The energy crisis and rising raw-material prices pushed industry to consider recovering value from waste. Yet this remained an embryonic form of recycling, technically rudimentary, often limited to simple shredding and remelting that produced heterogeneous, low-performance materials destined for low-value products.....© Reproduction Prohibited
