SpartanBio Mulch: Functional Biodegradable Mulch Sheets

Plastic pollution in agriculture, particularly associated with the use of mulch sheets, has become a growing environmental concern. Mulch sheets, whether conventional plastic or biodegradable, can degrade over time into smaller plastic particles known as microplastics (microplastics (MaP, > 5 mm), microplastics (MP, 1-5 mm), and nanoplastics (NP, <1 µm)). These plastics can accumulate in soils, waterways, and ecosystems, posing risks to environmental and human health.

The scale of microplastic pollution from mulch sheets affects millions of people globally, including farmers, agricultural workers, consumers, and communities reliant on agricultural ecosystems for food and livelihoods.

 In India, plastic mulch sheets are extensively used in various crop cultivation practices, including vegetables, fruits, and cash crops like cotton. According to a report by the Central Pollution Control Board (CPCB) of India, the country generates around 26,000 tonnes of plastic waste daily, with a significant portion attributed to agricultural plastic waste, including mulch sheets.

Globally, plastic mulch sheets are widely used in intensive agriculture, particularly in countries with large-scale commercial farming operations. According to a study published in the journal Environmental Science & Technology, it is estimated that more than 1.3 million metric tons of plastic mulch films are used annually worldwide.

After 32 years of using plastic mulch film in an agricultural area at Shenyang Agricultural University in China, microplastic concentrations in the topsoil (0–10 cm) increased from 7183 to 10,586 particles/kg, averaging 8885 particles/kg.

In 19 provinces across China, a study revealed higher microplastic concentrations in fields where plastic mulching was used continuously for 24 years. Particle amounts ranged from 31–129.6, 169–446.1, and 728–1422.4 particles/kg soil in fields with 5, 15, and 24 years of continuous mulching, respectively.

Microplastics present health hazards to humans and wildlife upon ingestion or absorption, often carrying harmful additives and pollutants that can lead to toxicity, bioaccumulation, and adverse health outcomes. These microplastics, originating from mulch sheets, disrupt ecosystems, endanger marine life, and contribute significantly to environmental degradation. They also serve as carriers for pollutants and contaminants, extending their impact beyond their initial source and affecting ecosystems on a broader scale

Several factors contribute to microplastic pollution in agriculture like mulch sheet degradation, soil contamination, water contamination, ecosystem impacts, waste management practices, education and awareness, and regulatory measures.

Proposed Solution:

Replacing conventional or biodegradable mulch sheets with Spartan Bio Mulch, Functional Biodegradable Mulch Sheets, which utilizes natural polymers, agricultural waste composites like rice bran or coconut shell powders, plastic-degrading bacteria, soil-enriching bacteria, and herbicides, involves a multi-step process with advanced technologies and sustainable practices.

Switching to functional biodegradable mulch sheets achieves the following:

a) Converts into natural components, lowering soil microplastic contamination and promoting healthier soil ecosystems and sustainable farming practices.

b) Reduces microplastic runoff by decomposing into environmentally safe materials, lowering the threat of water contamination and harm to aquatic organisms. c) Lowers the buildup of enduring microplastics in ecosystems, lessening adverse impacts on wildlife, biodiversity, and ecosystem functionality, etc.

Functional biodegradable mulch sheets, such as Spartan Bio Mulch, offer an innovative and sustainable solution for agricultural practices. These mulch sheets are crafted from a combination of natural polymers, composite materials like volcanic ash or agricultural waste materials like rice bran or coconut shell powders, groundnut shell powder, corn cob powder, plastic-degrading bacteria, soil-enriching bacteria, herbicides, and natural UV absorbers.

The process of creating these mulch sheets begins with selecting natural polymers like polylactic acid (PLA) or chitosan, derived from corn starch or shrimp/crab shells, respectively. These polymers provide the base material for the sheets and impart biodegradability and eco-friendly properties. Agricultural waste materials are then incorporated into the mix to enhance mechanical strength, flexibility, and biodegradability.

 One of the key components of these mulch sheets is the inclusion of plastic-degrading bacteria, such as those from the Pseudomonas or Bacillus genera. These bacteria produce enzymes like polyhydroxyalkanoate (PHA) depolymerase, which breaks down synthetic polymers like PLA or polyethylene, aiding in biodegradation when the sheets are disposed of in soil or composting environments.

Additionally, soil-enriching bacteria are added to improve soil fertility and plant growth. These beneficial bacteria, such as nitrogen-fixing or phosphate-solubilizing bacteria, colonize the soil upon mulch decomposition, providing essential nutrients and enhancing soil structure.

To address weed control, herbicides or weed-suppressing compounds are incorporated into the mulch sheets as chemical actives. These compounds help manage weed growth under the mulch, reducing competition for nutrients and water with crop plants.

Moreover, natural UV absorbers are included to protect the mulch sheets and underlying soil from UV degradation. These UV absorbers prevent premature degradation of the sheets and maintain their integrity over time.

The production process involves extrusion or compounding technologies, where the blended ingredients are melted and formed into continuous sheets. Rigorous testing and quality control measures ensure mechanical strength, biodegradability, herbicide release rates, UV protection efficacy, and compatibility with soil environments.

Once validated through laboratory testing, the functional biodegradable mulch sheets are applied in agricultural fields. Field trials and monitoring assess their performance in weed control, soil enrichment, UV protection, crop yield, and environmental impact.

The preparation of functional biodegradable mulch sheets involves a comprehensive approach integrating biotechnology, materials science, and agronomy. This innovative technology provides sustainable solutions for weed control, soil health improvement, UV protection, and crop production enhancement while reducing plastic pollution and chemical inputs in agriculture.

The solution of functional biodegradable mulch sheets serves a wide range of stakeholders in the agricultural sector, including farmers, agricultural workers, consumers, and communities reliant on agricultural ecosystems. Here's how this solution impacts their lives:

Farmers benefit from functional biodegradable mulch sheets as they provide effective mulching while reducing environmental impact. These sheets break down into non-toxic compounds, minimizing the generation of harmful microplastics during degradation.
