One-Sentence Definition
Recycled Acrylic (r-PMMA) is polymethyl methacrylate (PMMA) that has been recovered from post-industrial or post-consumer waste and reprocessed—mechanically or chemically—into new acrylic products with properties comparable to virgin material.[Trinseo]
Detailed Explanation
Acrylic, also known as PMMA, is a transparent, lightweight, and durable plastic widely used in displays, furniture, and protective covers. r-PMMA refers to acrylic that has completed its first life cycle and is then collected, sorted, and recycled. There are two main recycling methods:
Mechanical recycling: Waste acrylic is ground and remelted into new products. This method is simple but may slightly degrade material properties over multiple cycles.
Chemical recycling: Waste PMMA is depolymerized at high temperatures (350–450°C) back to its original monomer (MMA), purified, and then repolymerized into new PMMA. This process can produce r-PMMA with mechanical, optical, and aesthetic properties nearly identical to virgin acrylic, enabling true closed-loop recycling.[PMC Article]
Key Components of r-PMMA
Source Material: Post-industrial scraps (e.g., offcuts from manufacturing) and post-consumer products (e.g., used display stands, furniture).
Recycling Process: Mechanical (grinding, remelting) or chemical (depolymerization, purification, repolymerization).
Quality Control: High-purity recycling ensures r-PMMA matches virgin PMMA in clarity, strength, and durability.
Environmental Impact: r-PMMA can reduce carbon footprint by up to 70% compared to virgin acrylic, supporting circular economy goals.[Trinseo]
Real-World Applications
Recycled acrylic is increasingly used in:
Retail and Exhibition Displays: Sustainable display stands and signage.
Home and Office Products: Storage boxes, protective covers, and custom furniture.
Automotive and Construction: Lightweight, durable panels and trim.
Sustainable Packaging: Eco-friendly alternatives for brands seeking green credentials.

Related Concepts
Virgin Acrylic: PMMA made from new, non-recycled raw materials.
Sustainable Materials: Materials designed to minimize environmental impact throughout their lifecycle.
Circular Economy: An economic system focused on reusing and recycling resources to reduce waste.
Recycled Plastics: Plastics recovered and reprocessed from waste streams, including r-PMMA, r-PET, and r-PE.
Mechanical vs. Chemical Recycling: Mechanical is physical reprocessing; chemical breaks down polymers to monomers for higher purity.
