Key Findings

  • 01The production of bone graft materials from femoral heads is environmentally viable.
  • 02Chemicals used for degreasing and deantigenization are significant contributors to environmental impact.
  • 03Electricity consumption is a major factor across most impact categories.
  • 04Bone graft granulates have a slightly higher environmental impact than bone blocks, partly due to packaging.
02

Application

Design takeaway

Prioritize the selection of less impactful chemicals and energy-efficient processes when designing or specifying the production of allograft bone materials.

How to apply

When designing medical devices or procedures that require bone grafting, investigate the feasibility of using ethically sourced and processed allografts derived from repurposed human tissue.

Project actions

  • 01When considering material sourcing, explore options that align with circular economy principles.
  • 02Quantify the environmental impact of your chosen materials using LCA tools if possible.
03

Method & Evidence

AimTo assess the environmental impacts associated with the production of bone graft materials derived from repurposed femoral heads for dental implantology.
MethodLife Cycle Assessment (LCA)
ProcedureA cradle-to-gate LCA was conducted on the production of cancellous bone blocks and granulates from femoral heads. Environmental impacts were quantified using the ReCiPe midpoint and endpoint assessment methods within OpenLCA software.
ContextMedical waste management and dental implantology

Variables

IVProduction method of bone allografts (from femoral heads vs. other sources).
DVEnvironmental impact metrics (e.g., CO2-Eq, ecotoxicity).
CVType of bone graft material (block vs. granulates), processing chemicals, packaging.
04

Strengths & Limitations

Strengths

  • +Application of a recognized LCA methodology.
  • +Focus on a specific, relevant medical application.

Limitations

The specific chemicals and energy sources used in the study might not be representative of all tissue banks.

Reliability & validity

The study's reliability is supported by the use of established LCA software and methods. Validity is enhanced by focusing on a specific production process, though generalizability may be limited by variations in practice.

Think critically

How might the environmental impact of this process change if the source of the femoral heads or the processing facility's energy grid were different?

05

Design Principles

"Embrace waste valorization by integrating byproducts from one process as resources for another, thereby closing material loops."

This research demonstrates a practical application of circular economy principles within the medical field. By repurposing a surgical byproduct, designers and engineers can reduce waste and the demand for virgin materials, contributing to more sustainable healthcare practices.

06

What This Means for Your Design

Using bone from hip replacements to make bone grafts for dental implants is better for the environment than making new materials.
