Abstract
Purpose
This paper aims to present a proposal for the restoration of a silver crown by means of fitting pieces produced by the process of 3D modelling and rapid prototyping. It also analyses the benefits of this procedure in restoration of objects weakened by corrosive processes.
Design/methodology/approach
Elemental chemical analysis was carried out in the alloy used in the manufacture of the crown and the constructive and corrosive processes present were studied. Three fitting pieces were modelled and prototyped in wax casting by the stereolithography apparatus system aiming to restore the part and protect the original metal against impacts and external tensions which could speed up some deterioration processes.
Findings
The procedure presented in this paper has shown that formal and dimensional accuracy, only achieved by means of 3D technologies, made the restoration and mechanical stability of the crown possible without the use of adhesives or welding.
Originality/value
The proposed procedure is a new restoration alternative which causes minimal impact to the object and abides by the main standards for modern conservation. It is made with metal which is compatible with the original piece, retractable and easily identifiable.

Abstract
This chapter provides an overview of how, from a multi-stakeholder approach, Brazil can recover, fight against climate change and build an inclusive and sustainable future for itself. The interdependencies of the climate change action and current COVID-19 pandemic are discussed through extensive secondary data research to provide an updated context on Brazilian initiatives or the lack thereof. Through a multi-stakeholder methodological approach, the response and recovery actions of Brazil's government are assessed and future scenarios are developed for the country.
