“…The recollection and processing of waste avocado seeds can be a new source of starch and provide income opportunities, since this macromolecule is widely employed in different fields for textiles, pharmaceutical excipients as a binder and adhesive, food processing, beverages, and more. In addition, many biopolymers based on starch can be obtained [126,127].…”

Significant problems have arisen in recent years, such as global warming and hunger. These complications are related to the depletion and exploitation of natural resources, as well as environmental pollution. In this context, bioprocesses and biorefinery can be used to manage agro-industrial wastes for obtaining high-value-added products. A large number of by-products are composed of lignin and cellulose, having the potential to be exploited sustainably for chemical and biological conversion. The biorefinery of agro-industrial wastes has applications in many fields, such as pharmaceuticals, medicine, material engineering, and environmental remediation. A comprehensive approach has been developed toward the agro-industrial management of avocado (Persea americana) biomass waste, which can be transformed into high-value-added products to mitigate global warming, save non-renewable energy, and contribute to health and science. Therefore, this work presents a comprehensive review on avocado fruit waste biorefinery and its possible applications as biofuel, as drugs, as bioplastics, in the environmental field, and in emerging nanotechnological opportunities for economic and scientific growth.

“…According to Tesfaye et al (2018), the disposal of large food waste poses substantial environmental impacts, and there is growing attention to it due to its effect on the environment (Tesfaye et al, 2020). CP is the most effective approach for avoiding waste (Aschemann-Witzel et al, 2020).…”

“…According to Ingrao et al (2018), the growing demand for food and the reduced adverse impacts of related supply chains represent a significant challenge in the 21 st century. According to the European Union, food waste increased substantially, and it was estimated that 126 million tonnes could be produced in 2020 (Tesfaye et al, 2020). As food waste at the consumer level is a recent research topic, the related factors are still under analysis and discussion, and waste can be a valuable resource for producing chemicals, materials, and fuels (Sáez-Martínez et al, 2016).…”

“…As food waste at the consumer level is a recent research topic, the related factors are still under analysis and discussion, and waste can be a valuable resource for producing chemicals, materials, and fuels (Sáez-Martínez et al, 2016). Recycling of waste from food processing industries can also be in the form of livestock feed or by producing value-added products from the waste, as food wastes contain organic materials that are biodegradable and can be converted to bio-based materials (Tesfaye et al, 2020). Denham et al (2016) analyzed the environmental impacts of the fish fillet sector and reported that electricity consumption, leakage of refrigeration gas, and disposal of unused fish portions contributed to the higher greenhouse gas emissions in supply chains.…”

Adoption of cleaner production in a pupunha palm heart factory: a systematic literature review and a case study

2022

View full text Add to dashboard Cite

The pupunha (peach palm) palm heart production in the Vale do Ribeira (southern region of the State of São Paulo-Brazil) brings economic benefits to the region, and environmental risks with the generation of a large amount of waste. The Cleaner Production adoption in the pupunha palm heart factories is a strategy for reducing environmental impacts and generating profit, with consequent rational use of raw material, reuse of waste, and new equipment installation. This research aims to evaluate the Cleaner Production adoption's environmental and economic benefits in the reuse of waste generated in pupunha palm heart processing. The case study was carried out in a factory, using direct observation, interviews, and documentary data. The calculation of ROI was an adequate tool for economic evaluation, and the adoption of gondolas in the stages of material separation and waste treatment provided improvements in the production processes. The Cleaner Production application increased the theoretical knowledge about the treatment and use of the waste, reduced the environmental impact, allowed the development of a new business, and generated economic gains through the creation of employment and increase of income.

Starch Stärke

A sustainable food waste management methodology has been proposed for the discarded seeds of avocados (Persia Americana mill) where starch is extracted from the seeds through a microwave assisted heating process using only water, and this starch is modified through chemical treatment into acrylamide starch and carboxymethylated starch. Native as well as modified variants of starch are characterized using fourier transform infrared spectroscopy (FTIR), which confirms the extraction of native starch and its chemical modification. The extracted and modified variants are then analyzed for their antioxidant properties against oxidative stress by checking their scavenging activity against DPPH (2,2‐diphenyl‐1‐picrylhydrazyl). Moreover, the three variants of starch are tested for hemolytic activity in order to determine whether they are harmful to human blood, finally these three variants are checked for their activity against Escherichia coli and Staphylococcus bacteria, the root cause in most cases of bacterial infection in humans. The starch variants are found to be excellent antioxidants and all three starch variants indicate a very low hemolytic activity and significant antibacterial activity in comparison to widely used antibiotic Ciproflaxin. All these results indicate that avocado seeds waste can be an excellent non‐conventional source of starch that can be used for sustainable applications in food and pharmaceutical industries.
