“…sulphuraria) could be heavier than those from terrestrial (lignocellulosic) biomass/livestock manure. , The absence of concurrent reduction of CO 2 and oxidation of VMs to CO in Figure indicates that the role of CO 2 as a mediator enabling a shift in the carbon distribution from oil to gas could be strongly governed by the molecular size of the VMs. In other words, CO 2 susceptibility could be highly contingent on the molecular size of the VMs, considering that the steric factor is closely related to the heat transfer rate. , To prove this hypothesis, the experimental setup for the pyrolysis of G. sulphuraria under CO 2 conditions was modified.…”

Microalgal biomass has a high CO2 fixation and growth rate when using CO2 as a carbon source. Moreover, biomass can also be employed as a carbon resource to produce biofuels and chemicals. As the growth rate of extremophilic microalgae remains unaffected by harsh conditions, the present study proposes that these microalgae (such as Galdieria sulphuraria) are a rapidly growing carbon resource for syngas production. Hence, two different experiments were performed as part of this study: (1) cultivation of G. sulphuraria under outdoor conditions and (2) conversion of G. sulphuraria into syngas. The productivity of G. sulphuraria under mixotrophic condition (0.82 g L–1 d–1) was about 1.6 faster than a widely cultivated Chlorella sp. HS2. Moreover, G. sulphuraria was converted into syngas using CO2 as a co-feedstock. The simultaneous reduction of CO2 and the oxidation of volatile matter (VM) from the thermolysis of G. sulphuraria promoted syngas formation. The chemical reaction was influenced by the molecular size of the VMs. In the presence of the Ni catalyst, low-molecular-weight VMs were formed owing to chemical bond scissions. Syngas formation under CO2 doubled compared with that under inert conditions. The findings suggest that G. sulphuraria is a feasible carbon source for CO2 fixation and chemical production.

“…Besides the applications for food and feed, insects can also be used for other industrial applications. There are many publications on the production of biodiesel or transportation fuel from lipids from the black soldier fly reared on organic waste (Jung et al 2022;Park et al 2022). Franco et al (2022) describe the process to arrive at skincare products from purified fat from black soldier fly larvae which improve skin conditions such as smoothing, revitalizing, moisturizing, and tightening.…”

An overview is given on recent developments in insects as food and food by reviewing the literature which has appeared during the last few years on edible insects. An outlook to the future is provided. About a decade ago, the attention shifted from harvesting insects in the tropics to farming insects all over the world for food and feed applications. Most production is targeted towards pet food, but it will turn to aquafeed in the next two decades. More than 80% of all publications dealing with edible insects appeared during the last five years. Crickets and mealworms are used for human food while the black soldier fly is the main species used as animal feed. The criteria to choose insect species are automation, cheap substrates, disease avoidance, and market potential. Genetics are increasingly explored to improve production. The environmental impact of producing insects compares well to other alternative proteins, in particular their capacity to degrade organic waste streams. Edible insects are not only a good source of nutrients but also seem to provide health benefits not only for humans and animals, but also for plants (left over substrate). The challenge of convincing Western consumers is reviewed and whether sustainability is an issue. Processing techniques are being developed. The sector of insects as food and feed is developing fast thanks to an increasingly conducive legislative framework. It will progress further, provided that the insect industry, academia, governmental organizations, and public society closely cooperate.

“…One of the strategies aimed at combating the menace of food waste is the conversion of unconsumed and discarded food items into usable products. In recent research, Mohanty et al [4], Jung et al [5], and Kazemi et al [6] studied the conversion of wasted food to bioenergy, biodiesel, and bioethanol respectively. Chhandama et al [7], Sharma et al [8], and Mahssin et al [9] also posited that food waste can be converted to biogas, biohydrogen, biofertilizer, bioplastics, asphalt binder, and other bioactive compounds.…”

Access to timely, affordable, and good quality food is a sine qua non for human existence. Unfortunately, huge volumes of edible foods are wasted or lost along the food value chain thereby impacting food security. Recycling and conversion of food waste ensure the appropriate utilization of the untapped resources in food waste. The current study reviews the biological (landfill, composting, anaerobic digestion, and fermentation) and thermochemical (incineration, pyrolysis, gasification, and hydrothermal carbonization) technologies for the conversion of food waste into clean energy, chemicals, and other utilizable products. The process, products, benefits, and drawbacks of these conversion technologies are also discussed. Commissioning of multidisciplinary and collaborative research is recommended to garner expert perspectives towards achieving cost-effective, ecofriendly, sustainable, and practicable food waste conversion technologies.
