Introduction
Overview of Sustainability in the Packaging Industry
Background: Packaging as the term denotes is a method of containing or storing the finished goods or products. Though packaging itself is not the mainstream product, businesses heavily depend on the kind of packaging it adopts for their product. There has been a long recorded history of the evolution of the packaging industry. Leaves, wood barks, and other naturally occurring materials were used as packaging materials during the middle ages. Gradually, as the industrial revolution began in the late 1750s, packaging methods and materials changed as well. This, in turn, created a high demand for packaging owing to the increased production of goods and transportation requirements. After World War-II, the packaging sector was disrupted by the use of plastics and aluminum foil. This provided the convenience of single-use and throw-away packaging, especially for Fast Moving Consumer Goods (FMCG) products. Current scenario and the need for sustainable packaging: Over the past two decades, plastics have dominated the packaging industry due to their ease of use and reliability. However, the use of plastics has left an irrevocable and damaging impact on the environment. It has been estimated that more than 8.3 billion tons of plastics have been produced since the 1950s, of which only 9% was recycled and 12% incinerated1. Over 70-80% of the single-use plastics get accumulated in landfills, thereby polluting the land. With growing awareness of the hazardous impact caused by using single-use plastics, sustainability surfaced in the packaging space in the late 2000s with a need to address the environmental footprint. If the below-mentioned criteria are fulfilled, the packaging is considered sustainable.- Meets market criteria for performance and cost
- Is sourced, manufactured, and recycled using renewable energy
- Is produced using the best industrial practice that does not leave an ecological footprint
- Is produced with materials that can be recycled or shall be bio-decomposable after single-use
- Shall be effectively recovered using biological/industrial closed-loop cycles.

Indicators & Metrics for Assessing Packaging Sustainability
Indicators are key pointers that may express a positive or negative movement towards the stated goal. There may be several indicators to ascertain whether the packaging is sustainable or not. These indicators allow stakeholders to understand the status of their packaging models and establish baselines for their future initiatives.2 The Global Protocol on Packaging Sustainability (GPPS) provides over 40 different sustainable packaging indicators and metrics that span material use, water use, energy use, clean production, transport, cost, and performance, among other areas, which impact the value chain. Some of the commonly used indicators primarily pertain to the eco-friendly friendly aspects of packaging and the recoverability after its use. A few of the critical indicators for sustainable packaging are illustrated below:
As stated above are some of the mainstream indicators in the packaging industry. However, there may be several other indicators based on case-to-case business needs, which stakeholders are required to address prior to undertaking business decisions.
Emerging Start-Ups & New Packaging Materials
Apart from the prevalent recycling and closed-loop mechanism to keep up with the demands of sustainable packaging, there is a steady increase in the development of innovative materials that may be an alternative to conventional materials used in packaging. Some of the trending alternatives are eco-friendly packaging materials, which are compostable and renewable and leave zero ecological footprints.The innovation of Packaging Materials in Existing Companies
Sustainable packaging may pose a challenge, as there are myriad parameters and regulations to be implemented that can have cost and time implications on mid-level and small manufacturing companies. The need for recycling shall be circumvented by investing smartly on the research and development of eco-friendly materials. Nowadays, several existing companies have invested in research and have been successful in implementing the much-needed change in materials. Some of the new materials innovated by existing companies are illustrated below:
Emerging Start-Ups
The awareness, as well as the demand for sustainable and eco-friendly packaging solutions, is increasing among consumers; this rising demand can be fulfilled by start-ups addressing various possibilities of developing sustainable solutions. There are several start-ups that address the need for disruptive packaging materials with zero waste, which leave no ecological footprint. Additionally, some start-ups focus on implementing sustainable solutions by various processes, such as recovering the total energy of the packaging waste by incineration or recycling the packaging waste in a manner that leaves no ecological footprint. Several start-ups have emerged successfully across the globe in this effort. A few start-ups using sustainable packaging solutions are listed below.
