Unilever is leading the way in plastic recycling through cutting-edge technology, strategic collaborations, and a strong commitment to sustainability. The company’s initiatives focus on creating a circular economy for plastics by improving sorting efficiency, promoting consumer participation, and reducing environmental impact. Here’s a closer look at Unilever’s game-changing efforts.
1. AI-Enabled Sorting Machines
In collaboration with Alibaba Group, Unilever launched the “Waste-Free World” initiative in China, introducing AI-powered recycling systems that automatically identify and sort plastic packaging. These machines utilize artificial intelligence to classify plastic bottles by type and grade, enhancing the quality of recycled materials. Consumers participate by scanning a QR code with Alibaba’s Alipay e-wallet before depositing bottles, promoting responsible recycling behaviours.
How Is Unilever Using AI to Improve Plastic Sorting?
AI-Powered Material Identification
Unilever leverages advanced AI algorithms to classify plastic bottles by type and grade, ensuring higher-quality recycling and reducing contamination in the waste stream.
QR Code Integration
Consumers scan a QR code using Alibaba’s Alipay e-wallet, which tracks recycling activities and rewards users with coupons and green energy points.
Advanced Vision Systems
AI-driven deep learning analyzes the shape and size of plastic items for precise sorting.
Wireless Cameras & Cloud Connectivity
Some machines use wireless cameras to capture images, analyze waste types in real-time, and generate reports for enhanced consumer awareness.
Automated Sorting Mechanisms
Identified plastics are sorted into designated storage compartments, improving processing efficiency.
By combining these technologies, Unilever enhances recycling rates and incentivizes consumer participation in sustainability efforts.
Beyond AI-powered sorting, Unilever is tackling another major challenge: making black plastic recyclable.
2. Innovations in Black Plastic Recycling
Historically, black plastic posed recycling challenges due to its carbon black pigment, which optical sorting machines couldn’t detect. Unilever addressed this by developing detectable black colorants, enabling the recycling of black plastic packaging. This advancement has been applied to brands like Axe, with plans to extend to others such as TRESemmé, ensuring black plastic remains within the circular economy.
3. Commitment to Circular Packaging
Unilever has set ambitious goals to make all its plastic packaging reusable, recyclable, or compostable by 2025. The company is:
Reducing Virgin Plastic Usage: As of 2023, the company achieved an 18% reduction in virgin plastic use compared to 2019, aiming for a 30% reduction by 2026 and 40% by 2028.
Incorporating Recycled Materials: Increased recycled plastic usage to 22% of global plastic packaging (2023); aims for 25% by 2025.
Enhancing Recyclability:Currently, 53% of Unilever’s packaging is recyclable, reusable, or compostable—efforts ongoing.
Waste Management Investments: Partnering globally to collect and process 600,000 tonnes of plastic annually.
4. Broader Sustainability Goals
Unilever’s efforts extend beyond recycling, focusing on system-wide changes, including:
Refillable and Reusable Packaging: Encouraging consumers to adopt refill stations and reusable containers.
Alternative Materials: Exploring options like paper, glass, and aluminum as eco-friendly packaging substitutes.
Extended Producer Responsibility (EPR): Advocating for policies that hold companies accountable for packaging waste.
Support for Waste Collectors: Unilever Collaborating with organizations like UNDP in India to empower informal waste collectors.
5. Consumer Engagement in Recycling
Unilever actively involves consumers in its recycling initiatives:
AI-enabled machines in China reward users for depositing plastic bottles, fostering a culture of responsible waste disposal.
Digital tracking via QR codes ensures transparency in the recycling process.
Through these comprehensive efforts, Unilever is making significant strides in revolutionizing plastic sorting and recycling, contributing to a more sustainable and circular economy.
