Transition toward circular economy in the agrifood seedling phase: A Life Cycle Assessment on tomato trays.

National and international guidelines call for greater environmental sustainability in agriculture through the introduction of the circular economy. Recent studies investigate the introduction of new technologies and methodologies in the field, however, few focus on initial stages at the plant nursery or the management of the involved materials, and none scientifically calculate their environmental impact. To fill this gap, this paper focuses on an Italian case study that quantifies the environmental impact of the traditional seed trays used worldwide for growing, transporting and transplanting tomato seedlings, proposing and evaluating two alternatives from a circular economy perspective.

Immunohistochemical localization of peroxisomal enzymes during rat embryonic development.

Peroxisomes are cytoplasmic organelles involved in a variety of metabolic pathways. Thus far, the morphological and biochemical features of peroxisomes have been extensively characterized in adult tissues. However, the existence of congenital peroxisomal disorders, primarily affecting tissue differentiation, emphasizes the importance of these organelles in the early stages of organogenesis.
