Key Findings

  • 01Cultivation is the primary environmental hotspot in both bread and beer production systems.
  • 02Innovative circular products generally exhibit lower environmental impacts than conventional products.
  • 03Circular strategies notably reduce land use and marine eutrophication, particularly in organic production scenarios.
  • 04The fully circular scenario outperformed the conventional system across 13 impact categories.
02

Application

Design takeaway

Prioritize the integration of waste streams into production processes and focus on optimizing upstream cultivation and processing to achieve maximum environmental benefit.

How to apply

When designing new food products or processes, conduct an LCA to identify environmental hotspots and explore opportunities for incorporating by-products from other industries.

Project actions

  • 01When researching a product, consider its entire lifecycle from raw material to disposal.
  • 02Look for opportunities to use waste materials from one process as ingredients in another.
03

Method & Evidence

AimTo evaluate the environmental impacts of producing bread and beer within a circular economy framework, comparing them to conventional production methods.
MethodLife Cycle Assessment (LCA)
ProcedureA cradle-to-gate LCA was conducted for innovative bread (using brewery-spent grain) and beer (using unsold bread) production, alongside conventional counterparts. The analysis covered upstream supply chain processes, including cultivation, milling, malting, and ingredient production, and identified environmental hotspots.
ContextAgri-food sector, specifically bakery and brewing industries.

Variables

IV["Production system (conventional vs. circular)","Product type (bread vs. beer)"]
DV["Environmental impact categories (e.g., land use, marine eutrophication, global warming potential)"]
CV["Cradle-to-gate scope","Specific upstream processes analyzed (cultivation, milling, malting, etc.)"]

Strengths & Limitations

Strengths

  • +Application of a robust methodology (LCA) to a relevant industrial context.
  • +Comparison of innovative circular products against conventional benchmarks.

Limitations

Conducting a full LCA can be complex; focus on key impact categories relevant to your design.

Reliability & validity

The study's reliability is supported by the use of the established LCA methodology. Validity is enhanced by comparing innovative circular products against conventional ones within the same defined scope.

Think critically

How might the 'allocation constraints' mentioned in the study affect the perceived benefits of circular products in different economic contexts?

05

Design Principles

"Design for circularity by identifying and integrating waste streams as valuable inputs."

This research highlights the tangible environmental benefits of adopting circular strategies within established food production systems. Designers and engineers can leverage these findings to advocate for and implement resource-efficient processes, reducing waste and minimizing ecological damage.

06

What This Means for Your Design

Making bread and beer using waste from the other industry is better for the environment than making them the usual way.

How to use in your project

  • 1.Use the LCA methodology to assess the environmental impact of your design choices.
  • 2.Reference the findings on circularity to justify design decisions that reduce waste and resource consumption.
