Abstract
The contamination of agricultural soils due to the excessive use of synthetic plastics
in the food production and supply chain has caused the translocation of
carcinogenic compounds and endocrine disruptors contained in their formulations
to water bodies and farms, getting onto the food chain, generating diseases, and
putting human health at risk. This research established the state of knowledge by
using the methodology of systematic literature review, enabling the establishment
of hypotheses leading to focused, objective, and unbiased conclusions. It was found
that there is ambiguity in the scientific literature regarding the terms that refer to
alternative materials, so based on the results, appropriate definitions were
proposed. The materials of most scientific interest were plastic films, mulching films,
and controlled-release materials, which are still emerging topics in terms of quantity
and collaboration between countries worldwide. Although some alternatives have
been suggested, only a few ensure total and safe degradability on the soil
environment. One of the gaps is the lack of methodology on the identification,
quantification, and interactions of plastic particles under field conditions with heavy
metals, phthalate esters, and organic matter contained in the soil. Agave Salmiana
fibers were obtained, treated with alkali, and spun into yarns and a piece of woven
textile fabric. These three products were impregnated with beeswax using a
vacuum bag; to compare them with their synthetic counterparts, the diameters and
weight loss of the materials were measured. The highest weight loss in all
specimens occurred in the wax-impregnated fibers, yarn, and nets in the range of
12-38% over a period of 30 days, with significant differences with the synthetic
products. These natural fiber yarns and netting are presented as a proposal to
reduce the excessive use of synthetic plastics in agriculture; however, mechanical
characterization is necessary for them to be considered a functional alternative.
