The starting point of this research is to change the raw material used in the production of disposable tableware, which today is mostly produced using petroleum-based inputs and is gradually replaced by inputs from renewable sources. This substitution process has intensified in recent years due to plastic pollution, becoming a trend driven mainly by laws in several countries regarding the obligation of faster biodegradation. This conversion of the raw material triggers changes in the end of life of these products that can be composted, allowing a more sustainable life cycle, a major problem encountered with similar plastics, whose end of life generates problems almost without solution. Faced with these new characteristics, and with the possibility of more sustainable production systems, we can think of benefiting from a habit we struggle to change, which is that of disposability. With more sustainable attributes, the new disposable tableware can help at a very important point in the maintenance of water resources. The water forecasts for the large Brazilian urban centers, especially in relation to the Southeast region, reveal the possibility of water collapse in 2040. In the washing of a cup, up to 1200 ml are spent, which indicates that the domestic water impact can be significant and the possibility of domestic use of compostable disposable tableware can represent an intermediate option and possible execution if necessary. This work seeks to stimulate this discussion and in advance of possible changes, to investigate why disposable tableware is not yet used domestically in order to identify possible barriers to the implementation of this new proposal. The results of the research confirmed that we are not yet in the habit of using disposable tableware in our domestic routine and that there are barriers created by the use of plastic and its implications. But that the behavior has been changing in a silent and fluid way, as more than 80 percent of the interviewees order food at home, configuring the use of disposables in the domestic setting. These disposables are still derived from oil, increasing plastic pollution and its impacts.
