Why Eco-Friendly Reselling Is Booming
Sustainable reselling has never been hotter! Today’s shoppers are becoming much more cognizant of the environmental impact of fast fashion, overproduction and land waste. Eco-minded sellers now have a wealth of reselling options through online resale platforms like eBay, Poshmark, ThredUp, and through Facebook Marketplace.
· Environmental Awareness: Consumers are starting to search for second-hand items instead of purchasing new ones in an attempt to lower their carbon footprints.
· Cost: Second-hand items are often sold at a discount of 30-70% from retail prices, which makes the second-hand option preferable for cost-conscious buyers.
· Circular Economic Expansion: Reselling encourages a longer usable life of merchandise over disposal and discarding, which is in line with global trends towards sustainability and circular economies.
According to ThredUp’s 2025 Resale Report, it is anticipated that the secondhand market will reach $367 billion worldwide by 2029. Eco-friendly reselling is a chance to earn an income from product categories in the long-term.
