Originally scheduled for 2020, The International Conference on the Physics of Semiconductors was held from 27 – 30 June 2022 at the International Convention Centre (ICC) Sydney, Australia and attended by 391 participants from around the world.

The main objective of the Conference was to integrate social, economic and environmental sustainability practises and by minimising the carbon footprint by giving first consideration to sustainable products.

This was achieved through the promotion of public transport on the website, use of sustainable name badges, removal of printed products including satchels and program books, use of venue digital signage and ePresenter digital posters. ICPS 2022 was the first in its history to convert to digital posters and this will be a continued legacy for future conferences. The program had several unique elements including:

  • An Equity and Diversity Panel focusing on solutions to make the semiconductor physics community more inclusive.
  • A Women in Science and Technology Breakfast providing successful individuals in the industry the opportunity to share their career top tips.
  • A Next Generation Science program whereby 50 high school students attended in person to meet with a Nobel Laureate and other experts to gain insight into a career in science.
  • Digital posters and mini oral presentations which past ICPS’ have not had. Initially 152 authors and presenters submitted for a digital poster and 107 submitted for a hardcopy poster. The closer we got to the Conference, the interest increased for digital posters due to our marketing which resulted in 26 hardcopy posters presented vs 180 digital posters and 46 mini oral presentations.

ePresenter is the better choice when reducing carbon footprint and incorporating more sustainable practices, compared to hard copy posters.

ePresenter does not have a capacity limit. You can have hundreds to thousands of digital posters displayed on one digital terminal versus printing hundreds of single-use posters that require a large space to display. Our client chose to use ePresenter for this reason and the additional following benefits:

  • Less waste at the end of the event when materials such as adhesives, paper and signage would normally be discarded. This waste would have included the ink cartridges and packaging used to create printed posters. Ink cartridges can take between 400 and 1,000 years to decompose in landfill. Approximately 14% of deforestation is to produce paper which equates to 4.1 million hectares a year – an area the size of the Netherlands.
  • Less equipment and infrastructure setup eliminated walling, stand building, power, paper, signage, velcro, adhesives, printouts and single-use plastic. We use LED screens which are expected to have a lifecycle of 100,000 hours and can broken down in parts to be reused.
  • Less energy consumed compared to filling large halls with posters. The ICC Sydney is an award-winning and Silver EarthCheck certified venue where a percentage of the energy for the digital poster terminals was powered by their rooftop solar panels.
  • Less freight where authors do not need to travel to print and collect posters or have them shipped to event venues; and elimination of the need to freight hundreds of heavy and bulky poster board walling to the venue
  • Less venue space required means less resources (electricity, lighting, air-conditioning, cleaning, staff etc) and reduces venue hire costs.


The client’s objective to run an event with better sustainable practices was achieved across economic, social and environmental impacts with using ePresenter. ePresenter reduced the event’s overall carbon footprint by eliminating printed posters, signage, freight and energy consumed with the bonus of saving money with venue hire costs. With effective marketing, the team was able to convert 81 (76%) of hardcopy posters to the digital poster format.
