Global warming is one of the most dangerous threats that the entire world is facing today. The emission of greenhouse gases is increasing the impact of global warming. In such a situation, reduction of greenhouse gas emissions and finding an alternative source of energy is more and more important. The production of biogas from food wastes is considered a suitable way for the reduction of greenhouse gas emissions. Biogas could provide a more sustainable energy source than wood fuels for rural households in sub-Saharan Africa. Food waste is increasingly becoming a major problem in universities imposing serious environmental impact. Conversion of the food waste using anaerobic digestion (a series of biological processes in which microorganisms break down biodegradable material in the absence of oxygen.) to biogas energy is the best option for the management of food waste and for replacement of traditional fuel used (coal) which has been employed for cooking and heating application. In addition, the slurry produced from the process provides digestate which is a source of fertilizer. This paper investigates the potential of food waste left over in the Hawassa University cafeteria to produce biogas.12.75 m 3 per day of biogas from 255 kilograms of food waste per day was produced by 1200 number of students. A fixed dome cylindrical Chinese biogas having a digester volume of 20.3148 cubic meters (m³) with a retention time of 60 days and the diameter (d) and height (h) of the mixing pit are equal, which is 0.76 meters was required for the biogas production. Anaerobic Digestion is a biological process that takes place naturally when microorganisms break down organic matter in the absence of oxygen. In an enclosed chamber, controlled anaerobic digestion of organic matter produces biogas which is predominantly methane. Besides, food waste is increasingly becoming a major problem in every society imposing serious economic and environmental concerns. For this reason, many contemporary researchers are emphasizing finding sustainable solutions to recycle and produce energy from such waste. In this context, this paper aims to study and optimize the production of biogas from food waste by designing a fixed dome digester.

“…Aforementioned are some latest studies where plants have been used as a starting material for bioplastic production. Arikan et al utilized potato peels to generate potato peel bioplastic that showcased complete biodegradability within a month along with better water absorption in comparison with commercial bioplastics (Bezirhan Arikan and Bilgen 2019 ). Starch-based bioplastics have been made from Manihot utillissima (cassava) peels using modified PVA and citric acid to improve its mechanical properties.…”

Plastics are undebatably a hot topic of discussion across international forums due to their huge ecological footprint. The onset of COVID-19 pandemic has exacerbated the issue in an irreversible manner. Bioplastics produced from renewable sources are a result of lookout for sustainable alternatives. Replacing a ton of synthetic plastics with biobased ones reduces 1.8 tons CO 2 emissions. Here, we begin with highlighting the problem statement—Plastic accumulation and its associated negative impacts. Microalgae outperforms plants and microbes, when used to produce bioplastic due to superior growth rate, non-competitive nature to food, and simultaneous wastewater remediation. They have minimal nutrient requirements and less dependency on climatic conditions for cultivation. These are the reasons for current boom in the algal bioplastic market. However, it is still not at par in price with the petroleum-based plastics. A brief market research has been done to better evaluate the current global status and future scope of algal bioplastics. The objective of this review is to propose possible solutions to resolve the challenges in scale up of bioplastic industry. Various bioplastic production technologies have been comprehensively discussed along with their optimization strategies. Overall studies discussed show that in order to make it cost competitive adopting a multi-dimensional approach like algal biorefinery is the best way out. A holistic comparison of any bio-based alternative with its conventional counterpart is imperative to assess its impact upon commercialization. Therefore, the review concludes with the life cycle assessment of bioplastics and measures to improve their inclusivity in a circular economy. Graphical Abstract

“…Further to these efforts, other researchers are working on lessening the dependence on land-demanding crops for plastic production by switching to biomass from areas hostile to agriculture [55]. Moreover, carbon sources other than plants (shellfish [56], food waste [57], poultry feathers [58,59], sheep wool [60], etc.) are also successfully being made into fully degradable plastics with highly competitive properties and added values.…”

Bio-Based Plastics Production, Impact and End of Life: A Literature Review and Content Analysis

The accumulation of plastic wastes is one of the most widely spread problems affecting the environment. The reality that plastics can be made from renewable resources and degrade naturally has prompted academics to think outside the box to develop “better for the environment” items. In this paper, a bibliometric analysis of the scholarly publications related to bio-based plastics within the last 20 years is presented. Annual progression, geographic and research area distribution, and keyword co-occurrence were all examined. Six distinct clusters emerged from keyword analysis, which were further categorized into three directions: production to marketing; impact on the environment, economy, and society; and end-of-life (EoL) options. The major focus was on how to counter the weaknesses and challenges of bio-based plastics and take opportunities using the inherent advantages of bio-based plastics. Comprehensive studies regarding the impact of bio-based plastics on the environment, economy and social sustainability are still deficient. Although there are many promising innovations in this area, most of them are at the research stage. The benefits of bio-based plastics and better EoL options can be enjoyed only after increased production.
