The fact that a material is compostable means that it is biodegradable. This material can be recovered in the composting process. A biodegradable material decomposes under the influence of microorganisms, but can leave residue after a composting cycle and has no guarantee for toxic residues.

Experts offer these helpful tips for compostable labels:

• It is recommended that only compostable labels be applied to compostable packaging. This makes it easier for the end consumer to compost the product completely.
• Applying compostable labels to non-compostable packaging disrupts the recycling process and the labels end up in the landfill where the label is still intact, such as any glass or PET. It is necessary to take the time to evaluate the desired lifespan of the product and increase the likelihood that the package will end up in the right place, namely the customer's compost bin.

It is important not only to consider the desired end-of-life for the product, but also to make it as easy as possible for the consumer to achieve this eco goal. Providing clear instructions on end use of both the packaging and the label helps ensure that they are disposed of properly and do not end up in landfill.

• Both eco and performance goals should be considered for the label. Compostable materials perform slightly differently from the standard series due to their compostable adhesive. It is more sensitive to moisture, which affects label performance, and does not have the same shelf life as other non-compostable materials. For example, compostable thermal paper can be more easily marked or discolored than a standard thermal material.
• What is put on the label is also important. Consideration must be given to the types and use of inks and embellishments to ensure that the properties of the compostable label are not affected in a way that would alter the end-of-life solution. It is also important to know the amount of ink and foil applied to the label. A small amount will not affect recyclability, but too much can upset the balance.

These tips need to be incorporated into label design whenever there is an opportunity to pair compostable materials with compostable packaging.

As is known, once collected, recyclables are sent to central facilities to be sorted, cleaned and converted into new materials. Here, there are two different plant types according to the separation method. The first is the mechanical-biological treatment plants that separate mixed wastes for low-grade recycling. The second is material recovery facilities that focus on extracting reusable materials.

Our organization always follows domestic and foreign standards, applicable legal regulations and generally accepted practices in certification and labeling studies. In this framework, it also provides compost certification and C-Label (Compost Labeling) compost labeling services to businesses that request it.
