Sustainable Utilization of Ceramic Raw Materials

Introduction

As the global ceramics market targets $261.15 billion by 2026, the focus has shifted from mere mining to Circular Material Management. At Sunlets, we define sustainability not by what we use, but by how much we recover. By 2026, the industry is transitioning into a "Recycling First" model, driven by climate mandates and resource scarcity.

1. High-Content Recycled (HRC) Formulations

Circular economy execution is the defining trend of 2026.

The 85% Benchmark: Recent industrial projects have successfully produced ceramic bodies containing up to 85% recycled materials, including post-consumer glass and pre-consumer unfired scraps. According to research in the Journal of Cleaner Production, such HRC bodies can be sintered at temperatures 200°C lower than traditional stoneware, drastically cutting CO₂ emissions.

Internal Loop Excellence: Global leaders like LIXIL have reported a waste recycling rate of 95.3% in their 2025/2026 operations. In Battery Casting Machine workflows, sorting and grinding scrap by color for immediate reuse has become the standard for premium manufacturing.

2. Localization: Georesource Valorization & Logistics Decarbonization

Sourcing closer to the production plant is the "new normal" in 2026 to mitigate Scope 3 emissions.

Utilizing regional geological resources, such as Clay Schists, as sustainable alternatives to rare feldspar reduces transportation-related carbon footprints by 15-20%.

Process Adaptation: Sunlets’ high-pressure technology utilizes AI-driven formulation compensation to adjust for the mineralogical variability of local clays, ensuring that high-end sanitaryware maintains structural integrity and ±0.3% dimensional tolerance.

3. Cross-Industry Waste Valorization

2026 marks the year where "waste" becomes a primary feedstock via advanced materials science.

Beyond Traditional Clays: Innovative research (e.g., from the 2025 ICTECSS Conference) demonstrates the successful integration of agricultural residues (rice husk ash), electronic waste, and glass fiber into ceramic matrices for Functional Insulating Ceramics.

The technical barrier to using cross-industry waste lies in Rheological Control. Sunlets' proprietary Eco-friendly Deflocculants allow for the uniform suspension of heterogeneous waste particles in casting slips, enabling mass production of sustainable "Green Ceramics."
