Application

Design takeaway

Prioritize biodegradable or recyclable materials for consumables like pots and explore alternative, sustainable growing mediums to minimize the environmental burden of urban agricultural systems.

How to apply

When designing or specifying components for urban agriculture or similar controlled environment systems, conduct a life-cycle assessment of material options, focusing on end-of-life impacts and resource depletion.

Project actions

  • 01When choosing materials for your design, think about where they come from and where they go after use.
  • 02Consider the energy needed to run your design and look for ways to make it more efficient.

Method & Evidence

AimTo assess the environmental impacts of an urban vertical hydroponic farm in Stockholm, Sweden, using a life-cycle perspective and identify areas for improvement.
MethodLife Cycle Assessment (LCA)
ProcedureAn environmental performance evaluation was conducted for a case study vertical hydroponic farm. This involved assessing impacts from materials (growing medium, pots), energy consumption, and transportation, and comparing these to potential improvement scenarios.
ContextUrban vertical hydroponic farming

Variables

IV["Type of pot material (plastic vs. paper)","Type of growing medium (conventional soil vs. coir)"]
DV["Greenhouse gas emissions","Acidification impacts","Abiotic resource depletion"]
CV["System type (vertical hydroponic)","Location (urban)","Crop type (implied)"]

Strengths & Limitations

Strengths

  • +Utilizes a robust methodology (LCA) for environmental assessment.
  • +Provides specific, actionable recommendations for improvement.

Limitations

The specific environmental benefits of material substitutions can depend heavily on local recycling infrastructure and energy grids.

Reliability & validity

The reliability of LCA studies depends on the quality and completeness of the data used. Validity is enhanced by adhering to established LCA standards and conducting sensitivity analyses.

Think critically

How might the energy source for the vertical farm (e.g., renewable vs. fossil fuels) alter the overall environmental benefits of using paper pots and coir?

05

Design Principles

"Minimize the embodied energy and waste associated with consumables in closed-loop systems."

This research highlights that material choices in urban farming systems have substantial environmental consequences. Designers and engineers can leverage these findings to specify more sustainable materials, reducing the ecological footprint of food production within cities.

06

What This Means for Your Design

Using paper pots and a coconut-based soil alternative (coir) instead of plastic pots and regular soil in city farms can make them much better for the environment.
