To celebrate the arrival of Spring, for all orders over €500 including VAT, add to your order form the part number 473365 and Dulis will plant a tree in your name! Also join our Reforestation Programme funded by Dulis. Visit our page dedicated to Sustainable Development to find out more. By our estimates, the transport of one tonne of consumables can generate up to 130 kg of CO2. A tree absorbs an average of 35 kg of CO2 per year, so you need to plant 4 trees to “neutralise” the impact of transporting a tonne of plastic.
