The devastating effects of plastic pollution are evident in heartbreaking images of sea turtles with plastic straws lodged in their nostrils and seabirds unable to eat due to ingesting excessive marine debris. These cases highlight the urgent issue of single-use plastic waste, with an estimated 8 million tons of plastic entering our oceans every year, posing a severe threat to marine ecosystems. Faced with this reality, we must ask ourselves: Do businesses have a responsibility to integrate sustainability into product development from the outset?
As a responsible supplier, SUNNYPRO recognizes that ESG (Environmental, Social, and Governance) considerations are not just a trend but an essential commitment for brands. Beyond providing high-quality products, we also help our clients build sustainable supply chains, reducing the risk of public relations issues related to environmental concerns. Through innovative product design, we can minimize single-use plastics, promote resource circulation, and contribute to a greener future.

The Five Pillars of Circular Design in Product Development
Cycle Marker is an eco-friendly product designed specifically for the circular economy. We incorporate sustainability at every stage of product development through five key cycles:
1. Cultural Cycle
Cycle Marker combines tradition and innovation, preserving art and design culture while promoting green technology. Inspired by classic oil paint tubes, we have modernized the design to ensure both aesthetic appeal and practicality. This product is not just a tool for creativity but a medium for environmental awareness.
2. Product Cycle
With a refillable design, Cycle Marker extends product lifespan and reduces dependence on disposable stationery. Our "fiber reservoir refill system" offers a user-friendly refill process that minimizes plastic waste while ensuring long-term stability and performance. This system enhances product value and usability.
3. Plastic Cycle
Cycle Marker features an easy-to-disassemble design that allows all components to be recycled efficiently. Unlike traditional multi-material composite products that hinder recycling, our design ensures that every part can be properly sorted and reintegrated into the recycling system.
4. Material Cycle
We provide three material options: virgin PP, GRS-certified recycled PP, and biodegradable PP. These materials are fully compatible with existing recycling systems, ensuring that Cycle Marker adheres to environmental regulations and minimizes ecological impact.
5. Carbon Cycle
Certified under PAS 9017 standards, Cycle Marker’s biodegradable materials can naturally decompose into water, carbon dioxide, and organic matter within two years, preventing microplastic pollution. Even if the product inadvertently enters the natural environment, it will not contribute to permanent plastic waste.
Cycle Marker is not just an individual eco-friendly product; it is a comprehensive green solution built on circular economy principles. Its flexibility and integration make it an ideal choice for brands seeking long-term sustainability.
