Abstract
Recently, the packaging sector started to aim at the reduction of the ecological impact of one of its main materials: plastic. Pictures of plastic marine litter among others democratized bad reputation of this material. Hence, alternatives and bans started to appear. However, plastic displays various important properties for content protection, which are difficult to reach by using alternative materials at industrial scale. In the past, several materials were supposed to replace synthetic plastic in packaging, including polylactic acid, without success. The usages of plastic packaging make recycling complicate, and thermal recovery plants and landfills are still widely used to process these plastic wastes. Nevertheless, innovations have the potential to change this sector. Among materials that could replace plastic, nanocellulose appears as a solid competitor. Regarding recycling technologies, the recent discoveries of plastic enzymatic degradation could solve contamination and diversity problems encountered with plastic packaging wastes.
