This range of products is identified with the common seal Green Line, and a brief explanation of its features. Thus, there are four product groups:

- 100% biodegradable seal, compostable and organic: products that are manufactured from organic materials that decompose naturally by reaction to light, humidity, temperature and action of microorganisms. These products may be disposed of in organic waste containers for composting and will degrade in nature after about 2 years.
- reusable bag seal, . This group includes polyethylene bags that can be used at least 15 times and then be recycled, as required by the recently created UNE 53942 norm, promoted by the ANAIP association (Spanish Association of Plastic Producers). It also includes bags made of new materials, fabric, raffia, non-woven, cotton, PET, etc., very resilient and preventing extraction of more raw materials.
- Sustainable Product seal 100% renewable and recyclable. It groups environmentally-friendly paper products.
- Bag with FSC seal: responsible forest management (Forest Stewardship Council). Paper bags fulfilling FSC norms. This seal guarantees the raw material origin: well managed forests certified in accordance with the standards of the Forest Stewardship Council.
- Oxodegradable seal: plastic products with an addition of components intended to ease their decomposition under optimal light and humidity conditions
To give further assurance to consumers, these products meet the relevant standards in each case.
