In The Mix you can refill your own containers with Sesi washing up liquid, laundry liquid (bio and non-bio), fabric conditioner, hand soap, white vinegar for cleaning, surface cleaner, toilet cleaner and rinse aid. Re-using bottles reduces the amount of plastic in the waste stream and saves the energy spent in manufacturing or recycling. SESI products are vegan, biodegradable, cruelty free, and manufactured for SESI by an independent family firm in the UK. Since it was set up in 2006, SESI estimates that it has refilled more than 100,000 containers. You can find out more about Sesi here: https://sesi.org.uk/
You can pop in for refills during normal Mix opening hours, and also on the first Sunday of each month 10am-2pm alongside Scoopzerowaste dried food refill pop-up shop. You can bring any containers to refill, from old plastic bottles to glass jars or even milk cartons.
