In the current scenario of climate change and growing environmental awareness, sustainability in agriculture has become a fundamental pillar.
One of the key elements in this field is crop protection structures. These structures, whether greenhouses, tunnels, shading nets, or mulches, play a vital role in protecting crops against adverse weather conditions, pests, and diseases.
The choice of materials for these structures can have a significant impact on the environment. That’s why more and more farmers are opting for sustainable materials.
What makes a material sustainable?
A sustainable material is one that has a low environmental impact throughout its entire life cycle, from production to disposal.
Some of the characteristics defining a sustainable material include being renewable, recyclable, and preferably locally sourced to reduce the carbon footprint associated with its transportation.
Sustainable materials often have a long lifespan and require less maintenance, reducing their long-term environmental impact.
Sustainable materials for greenhouses and tunnels
Greenhouses and tunnels are essential for many agricultural systems as they enable control over the growing environment and offer protection against the weather.
Traditionally, these have been constructed using petroleum-derived plastics or glass, both with high environmental impacts. However, sustainable alternatives are available.
Certified sustainably managed wood is a viable option for greenhouse and tunnel frameworks. It’s a resilient, durable, and renewable material with a significantly lower carbon footprint than metals or plastics.
Regarding covering materials, biodegradable and recycled plastics are gaining ground. These offer the same functionality as traditional plastics but with a reduced environmental impact.
High-energy-efficient glass, although initially more costly, can provide long-term savings in terms of greenhouse heating and cooling.”

Sustainable shading mesh or nets
Mesh or shading nets are essential for controlling the amount of sunlight reaching crops and protecting them from certain pests and birds. While synthetic nets are common, there are more sustainable options available.
Some current companies offer shading nets made from recycled materials. These have the dual benefit of reducing the demand for new materials and preventing plastic waste from ending up in landfills or oceans.
Sustainable ground coverings for soil protection
Mulching is a technique used to protect soil and crops. Traditionally, this is done with plastics, but there are sustainable alternatives available.
Organic mulching uses materials like straw, leaves, or compost, not only protecting crops but also enhancing soil health by decomposing and adding nutrients.
Biodegradable mulches, made from corn or potato starch, are another option. They offer the same functionality as plastic mulches but decompose in the soil at the end of the growing season, reducing waste accumulation.
A more sustainable future
Moving towards more natural agriculture involves the use of sustainable materials and a critical review of all aspects of our production systems.
