In recent months, composting has gained significant prominence in waste management in Spain, establishing itself as a key strategy for sustainability, driven by both public action and citizen initiatives. Numerous autonomous communities and municipalities are developing projects and informational workshops, expanding infrastructure, and rewarding best practices in organic waste treatment.
In this context, the Valencia Interior Consortium (CVI) has stood out with its Compost Month campaign, which has involved schools, families, and town councils in five Valencian districts. This initiative has served to promote educational programs, creative workshops, and financial incentives that encourage ongoing participation in home and community composting.
Workshops, education, and awards for environmental commitment
The educational environment has played a significant role in recent initiatives . Schools have been recognized for their involvement in projects like Aula Composta (Composting Classroom), which aims to instill a culture of composting from an early age. The recognized schools participate in hands-on workshops and receive educational and promotional materials , reinforcing their learning and acknowledging their environmental commitment.
Meanwhile, in-person workshops at treatment plants and activities aimed at the public have introduced composting to people of all ages. Practical sessions, such as making Kokedama and vertical gardening, as well as botanical pressing, have been held, with dozens of participants.
The municipalities' commitment is evident in the fee discounts offered to families who demonstrate consistent and regular use of their home composters. This policy encourages citizens to maintain sustainable habits and register their organic waste contributions through dedicated apps.
New infrastructure and expansion of composting areas
The development of community composting areas continues to grow in northern Spain. Asturias, through Cogersa, has promoted the expansion and modernization of its facilities, allocating part of its financial resources to the creation of new areas and recycling centers adapted for the separate collection of biowaste . More than thirty municipalities will soon see improvements to their community composting spaces, and the implementation of local recycling centers is planned for all Asturian districts.
In Galicia, the O Carballiño Town Council has promoted the incorporation of fifty new single-family homes into its home composting program, supporting the initiative with the distribution of composters and manuals. Community management is also strengthened through ongoing supervision and guidance, as in the town of Lezo, where community composting is consolidated through regular visits and monitoring.
In the Canary Islands, the SUNA 2000 Recycling and Composting Plant remains a regional benchmark after more than 25 years. It has made progress in obtaining relevant permits, incorporating state-of-the-art machinery for shredding plant waste, and continuously producing compost and agricultural byproducts, thus facilitating the circular economy and the return of organic matter to the soil.
Local programs and citizen outreach
Promoting composting isn't limited to large-scale infrastructure or institutional programs. Numerous free workshops are available to the public, such as the one held at the "San José" Municipal Cultural Center as part of the GIRO program. These workshops offer basic tools for managing organic waste at home and introduce participants to vermiculture , raffling off materials and worm colonies to encourage continued composting.
Awareness is reinforced through creative and participatory activities that combine training, awards, and guidance to involve both families and educational groups . The entire process, from the initial treatment of organic waste to the use of the resulting compost, contributes to reducing the volume of waste sent to landfills and enriching soils in a more environmentally friendly way.
The numerous initiatives undertaken, from technical support to practical outreach , reflect the growing interest in and firm commitment to composting as an essential part of Spain's ecological transition. Institutional support, community participation, and environmental education are the key factors guiding progress toward more sustainable and efficient organic waste management.
