The challenges of a sustainable society cover a wealth of aspects, from transportation to energy production, from materials reuse to proper disposal of unavoidable waste. As the world becomes more city-centric, urban centers are becoming megapolis, and population densities reach extreme values, increasing pressures.Waste management becomes a critical activity in this context. The amount of waste produced in these megapolis is a major hindrance to society sustainability, and strategies for improving the eco-footprint of this waste are essential for our common future. These strategies resort both to less waste -through change of habits of the populations -and to improved recycling ratioswhich are achieved by improved technologies and (again) by changing population habits. Overall, the targets of the European Commission for 2020 impose a significant reduction of the landfill usage and require the establishment of a consensual circular economy where waste is seen as a resource.In this context, the strategies associated to pay-as-you-throw (PAYT) waste tariffs are deemed an essential economic instrument in waste management systems, promoting a change of perception on the generation and source-segregation of waste. The PAYT concept is one way to create a more efficient and fairer waste invoice bill calculation. Thus, waste tariffs cease to be collected in the traditional form of a fixed tariff (and/or associated with other factors) and are charged as a variable tariff, which depends on the quantity of waste produced. The advanced separation of waste that is inherently associated to a PAYT system acts as a positive reinforcement loop over the waste producers.Recently, in Portugal, Greece and Cyprus a novel project (LIFE-PAYT) was launched to assess the deployment (and associated reaction to) of pay-as-you-throw concepts in a diversity of scenarios (Dias-Ferreira et al. 2019). A total of five municipalities were engaged in the process, from large municipalities to small towns:

ResumoA intervenção de conservação e restauro de um estojo de faqueiro do século XVIII e o seu estudo histórico, material e técnico permitiram, não só restituir a integridade física e a função original do objeto, mas também aprofundar o conhecimento que se detém atualmente sobre os materiais e sistema construtivo deste tipo de mobiliário de conter, o qual materializa um importante testemunho das regras de etiqueta à mesa desenvolvidas na sociedade portuguesa de Setecentos, por influência da corte francesa de Luís XIV. O presente artigo pretende descrever o enquadramento histórico e estético em que este móvel surgiu, bem como as suas características técnicas e materiais com base nos resultados de análises laboratoriais.Palavras-chave: móvel de conter; estojo de faqueiro; estudo analítico; conservação e restauro. AbstractThe intervention of conservation and restoration of an eighteenth century cutlery case and its historical, material and technical study, allowed not only to restore the physical integrity and original function of the case, but also to deepen the knowledge about the materials and constructive system of the storage furniture, which embodies an important testimony of the table etiquette developed in the Portuguese society of the eighteenth century, under the influence of the French court of Louis XIV . This article aims to describe the historical and aesthetical context in which this piece has emerged and its material and technical features based on the results of the laboratorial analysis that were performed.
