# Reusable Candle Systems Sero Candles Swaps the Glass Jar for Recyclable Aluminum Inserts By Ben LoBue | Published 2026-08-05 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/sero-candles References: [serocandles](https://serocandles.com) & [serocandles](https://serocandles.com/pages/shop)  The Sero Candles system reimagines the candle around reuse and recyclability, replacing the disposable glass jar with a two-piece wood holder and a slim aluminum insert. When a candle burns down, the aluminum can be recycled alongside household cans while the wood container is kept and refitted with a fresh scent, cutting the waste that usually comes with premium candles. Each insert is poured with 100% soy wax, a natural wood wick, and phthalate-free fragrance oils, and it skips paper labels and glue in favor of laser-etched markings and welded wick clips. Designed and assembled in Tacoma, Washington, Sero offers three scents (Renew, Uplift, and Unwind) aimed at design-conscious consumers looking to cut single-use waste at home.
