Macnab-Lacey Prize

The Macnab-Lacey Prize is awarded to the undergraduate student design project team whose design project submission best shows how chemical engineering practice can contribute to a more sustainable world.

The objectives of the competition are to:

  • encourage students to think of sustainable development as a key element of their design projects
  • influence chemical engineering departments to position sustainable development at the heart of the curriculum
  • demonstrate that IChemE takes sustainable development seriously
  • provide a showcase for student talent, and reward achievement.

The winning entry will receive a prize of £750.

All design projects involving students on courses accredited by IChemE are eligible for entry. Each accredited department is asked to judge internally all of its student design projects and to choose one entry to submit to the judging panel. 

How to enter or nominate

The deadline for entry is the last Friday in June each year.

Detailed entry criteria can be found on the Sustainability Special Interest Group section of the website.

Entries should take the form of a summary of the project on no more than four sides of A4. The summaries will be reviewed by the judging panel, to select a short list of entries for the final round of judging. In this final round, entrants may be asked to make available their full design reports for detailed examination by the panel.

Entries should preferably be sent to

Alternatively they may be submitted on CD ROM by post.

The Macnab-Lacey Prize succeeds the historic Macnab Medal.
