Abstract

In this research, we investigated the reuse of synthetically produced greywater in the cultivation of micro greens. Microgreens are young plant shoots that already have cotyledons. In the cotyledon, there is a higher concentration of vitamins, minerals, and antioxidants that are important for us compared to the mature plant. The use of greywater for food production is associated with food safety risks, so our aim is to investi gate the effects of greywater on the micronutrient concentration and the yield in the microgreens. This was done by growing microgreens in clean water, untreated greywater and treated greywater that had under gone mechano-chemical treatment and observed the differences between the samples. The results showed that the edibility of the two crops was not drastically affected by the greywater, but the weight of the product was. The extent of this is plant specific. Further studies using real greywater samples are needed to establish the safe usability of greywater.
