The International Conference on Advanced Research on Sustainability and Intelligent Manufacturing RESIM 2022, held on the 2^nd and 3^rd of June 2022 was a great success.

Over 60 researchers from around the world. One of the most distance was Professor Javier Nakamatsu  at la Pontificia Universidad Católica del Perú over 9000km from Marinha Grande but beaten by Professor Seeram Ramakrishna of the National University of Singapore, at almost 12,000km .

This, the third edition of RESIM2022 was held in a hybrid format, with a presential session at CDRSP coupled to an online Zoom Session. Researchers at CDRSP were joined by researchers from other Portuguese Institutions. Enabling anyone, anywhere, to join the conference supports the Open Science Policy at CDRSP and also ensures that the carbon footprint of the event was kept to a minimum. Another first for the 3^rd edition was the introduction of a video poster session. In this the authors prepared a short video of 3 to 5 minutes which dealt with the key points of the poster and these were shown on the Big Screen at CDRSP and beamed to ZOOM Participants. AT the end of playing the video, one of the authors was present or online to answer any questions raised by the Audience. The standard of the video posters was very good and these can be observed on the RESIM2022 website.

Participants were welcome by Professor Geoffrey Mitchell from CDRSP, one of the chairs of the conference, who recalled the history of the event and its purpose. He highlight the keynote lecture for the morning of the 3^rd June which cam entirely from partner organisations in India. The was followed by a welcome from the President of the Polytechnic Professor Rui Pedrosa, who emphasized the alignment of RESIM and the activities of CDRSP to the sustainability policy of the Polytechnic and he welcomed the Open Science Policy in place for this conference.

The Opening Plenary Lecture was presented by Professor Seeram Ramakrishna of the National University of Singapore. He is listed as one of the most influential scientific  minds in the world. He presented remotely  his lecture titled “Net zero and circular economy shaping the future: Role of Materials”. This opened the conference perfectly with a focus on the  17 UN Sustainability goals, the challenges in recycling. It generated a lively discussion at the end of the lecture.  The first keynote lecture on  “Sustainable Biomaterials of Bacterial Origin and their use in Biomedical and Environmental Applications” was given by Professor Ipsita Roy of the University of Sheffield UK. She described fascinating research on polyalkylonoates  produced by bacteria. Professor Roy showed numbers applications in the medical applications including tissue engineering. The final keynote lecture was presented by Professor Artur Mateus of CDRSP which was titled “Circular Seas – the great challenge for plastics” and was focused on the CircularSeas Project at CDRSP which is exploring how to prepare high value goods for the Maritime Industries  using waste plastics recovered from the sea. He showed some exciting photos of large scale objects such as urban furniture and bus shelters which were 3d printed from a mixture of recycled plastics and calcium carbonate also recovered from sea shells.

The morning session was completed with two contributed lectures on  “Production of Hybrid Structures by Solid-State Welding” from the Polytechnic of Lisbon and on “Computational evaluation of sustainable water-cooled heat sinks manufactured by powder bed fusion” from Eva Silva a PhD student from the University of Minho.
