Currently, the circular economy model is the most accepted to reduce the amount of waste generated in various production systems, such as agriculture. This sector has great relevance in the economy of Spain due to its favorable climatic conditions. The application of a circular economy model in the peninsular agriculture would contribute to the reduction of the high volume of waste, while revaluing its by-products through several alternatives. Among the most profitable and viable options is the recovery of bioactive and beneficial molecules for health, such as pigments or phenolic compounds, among many others (Figure 1). Today, the vast majority of crops are conventional, which means they use pesticides to prevent various diseases or pests from causing great economic losses in the sector. However, since most of the waste come from conventional crops, there is a possibility that they contain pesticides. When carrying out the process of recovery and purification of biomolecules, there is the risk that pesticides will also be concentrated reaching limits that are harmful to health. Therefore, it is essential to know which pesticides could potentially be present in different food wastes, in order to correctly assess their presence/absence in the final revalued product and determine if it meets food safety standards.
