Every year, the global stationery industry generates:
12 million tons of plastic waste from production offcuts
28 billion liters of water consumed in manufacturing
6.5 million metric tons of CO₂ emissions
Traditional office supplies leave an invisible footprint long after leaving the factory. The LonGreen Series confronts this challenge through closed-loop manufacturing – transforming waste into opportunity.
LonGreen series products are made of post-consumer recycled plastics, reducing energy consumption, environmental pollution and greenhouse effect. Choosing these products, you will make a great contribution to a green future. Enjoy the beauty of nature at work.
Our proprietary Production System repurposes materials at three stages:
98.7% of manufacturing offcuts (plastic trimmings, metal shavings) are collected
Materials undergo laser-sorting and micron-level purification
Energy savings: 63% vs. virgin material processing
41% of each product contains recycled household/office plastics
Advanced PCR Plastic Stabilization prevents degradation
Carbon reduction: 2.1 kg CO₂ saved per kilogram of material
Water Recycling Rate: 89%
Renewable Energy Usage: 72% of factory needs
Byproduct Utilization: Even production dust becomes filler for packaging
Repurposed materials must meet exacting standards to rival traditional plastic products.
Our LonGreen series undergo quality checks from pellet injection to final assembly - identical testing to conventional Deli products.
We guarantee identical warranties for the whole product lines.
