Recyclable, compostable, biodegradable: what are the differences?
The practice aimed at encouraging the sustainable use of recoverable materials is now increasingly widespread, focusing attention on respecting the Planet and adopting increasingly eco-sustainable practices.
Recyclable, compostable, biodegradable: what are the differences? In modern society, there is an increasing focus on the health of the Planet thanks to good daily practices related to the correct management of waste recycling, but also to the knowledge of certain terms that concern precisely these actions. Terms such as biodegradable, compostable, recyclable, and non-recyclable materials are used. Having greater knowledge and awareness of these now commonly used terms means understanding what the real differences are in product disposal, in order to select and purchase objects, packaging, and materials knowing their disposal cycle in advance. So let's discover all the details. Read also: “Environmental labeling in packaging: what Italian regulations say”
What recyclable means
A recyclable material is a waste material that can be used again in production processes, such as glass, paper and cardboard, aluminum, plastic, and wood. In this regard, Directive 94/62/EC 17 recognizes the social and economic function of packaging. Packaging, in fact, must be designed to allow the recycling of at least a percentage of the materials used in compliance with European Community regulations, based on specific criteria concerning all stages of the packaging life, the so-called Life Cycle Assessment (LCA), the life cycle analysis that evaluates the environmental footprint of a product or service. In recent years, the percentage of recycled waste was recorded at 63% of national production; according to the 2021 Urban Waste Report, paper and cardboard account for 19.2% of the total. A figure that demonstrates how necessary it is to continue on this path, increasing the recovery of packaging as much as possible, making them more performing, reusable and, above all, recyclable. “The term recyclable is constantly used to define materials and products without a defined and shared reference. But the recyclability of a product goes beyond being technically recyclable: consumers must have access to a collection and recycling system, a recycler must be able to treat the material, and an end market is needed for the regenerated materials”. (Steve Alexander, President of The Association of Plastic Recyclers) The recycling of these materials has become possible only thanks to a correct and conscious waste separation operation, which allows these waste elements to be transformed into a resource, giving them new life, thus reducing materials that end up in landfills.
Non-recyclable materials
This refers to dry waste, also called unsorted or residual dry waste, waste products that cannot be recycled in any way. On the contrary, they must be disposed of in landfills, in a waste-to-energy plant, or in a facility where refuse-derived fuel is produced. Non-recyclable dry waste includes, for example: diapers, sanitary pads, cotton swabs, cotton, plastic objects that are not packaging, objects composed of various materials that are not easily separable, cash receipts, ceramics, ballpoint pens, dirty paper, sponges, etc.
What compostable means
A compostable material, after degrading, is transformed into compost, a substance rich in nutritional properties usually used as a fertilizer to enrich the soil. According to the UNI EN 13432 standard, a material is compostable if it is:
biodegradable;
disintegrable, meaning it consists of fragments smaller than 2 mm;
free of eco-toxic substances;
low in heavy metals and fluorinated compounds;
with pH, nitrogen, phosphorus, magnesium, and potassium values below the established limits.
Always according to European regulations, a product can carry the word “compostable” if it is biodegradable within just 3 months and if it passes ecotoxicity tests as proof that it cannot exert any negative effect on the environment. A classic example of compost is pruning waste and fruit and vegetable leftovers.
What biodegradable means
Biodegradable is defined as waste consisting of materials that decompose thanks to the action of microorganisms and bacteria, sunlight, or other natural atmospheric agents. Degradation can occur under two different conditions:
Aerobic - in the presence of oxygen: the substance produced can be used as a fertilizer or substrate in agriculture and floriculture;
Anaerobic - in the absence of oxygen: the substance produced, in addition to agriculture, can be used as a gaseous fuel.
A material can be defined as biodegradable if it is able to transform within six months; this means that what remains of the object must be able to be absorbed into the ground in the form of water, carbon dioxide, mineral salts, and other elements.
Difference between compostable and biodegradable
From what has been said so far, it is clear that for waste to be defined as compostable, it must inevitably be biodegradable and, conversely, a biodegradable material is not necessarily compostable because, for example, it might not disintegrate sufficiently during a composting cycle. The main difference between the two types of material therefore lies in the degradation speed, but also in the complete non-toxicity and chemical composition: this means that what is compostable returns to the earth as a nutrient substance in the form of compost, while the biodegradable returns to nature in the form of mineral salts and other simple elements.
Cart-One's eco-sustainable commitment
The main problem, until a few years ago, was the inability to dispose of packaging, containers, and other plastic objects made of non-recyclable materials, which therefore ended up in unsorted waste. Today, thanks to new circular economy models, it is possible to produce ecological, safe, and advantageous materials for the environment, health, and the economy. Cart-One, for example, has decided to invest more and more in sustainability and innovation, with great sensitivity towards environmental protection policies. Always a promoter and implementer of the circular economy, Cart-One has adopted the produce-consume-regenerate-recover model, thanks to which production waste becomes a reel and then a box again. In the packaging universe, these actions translate into the use of clean and innovative technologies, an eco-design understood as a packaging design that pays maximum attention to raw material savings, and with the continuous improvement of production processes aimed at reducing water, air, and soil impacts. ECOGRIP, for example, is the corrugated cardboard alternative to plastic shrink film, developed by the joint experience of the Paneuropean Alliance Blue Box Partners (BBP) of which Cart-One is a member. ECOGRIP eliminates the need to use a single-use plastic shrink wrap when transporting multiple bottles. It provides 100% biodegradable packaging, designed to fit any type of bottle on the market.
