An eco-friendly fertilizer

Putretti saves resources: physical, energy, emissions, time and human resources. The carbon footprint of Putretti is about 88% smaller than that of artificial fertilizers. The production process consumes fewer natural resources and less energy, while the amount of landfill waste is reduced. Putretti is produced from local materials, therefore reducing imports of fertilizers from abroad, ultimately improving Finland's self-sufficiency in fertilizers.
