“…(0:0:6). When a biomass is burned and the volatile substances are released, a solid combustible residue known as fixed carbon (FC) is left behind, indicating a prolonged combustion duration of the biomass sample and an increase in the sample's heatharming potential (HHV) [15]. Given that it has a favorable impact on the energy potential of biomass, the fixed carbon content of biomass may be simply linked with the calorific value [16].…”

Energy sources that are sustainable and renewable include biomass resources. Efficient use of these biomass resources to provide a worldwide energy supply that is sustainable. The techniques that enhance this biomass's energy potential require a thorough grasp of its physicochemical characteristics. The energy content of biomass resources (HHV or NHV) is a crucial factor to consider when determining their suitability for energy production. In this work, proximate assessments of biomass materials (agricultural residues) and their blends were developed based on some published empirical model equations to investigate the impact on their net and high heating value.EFB, corncob, and groundnut shell blends' computed net heating value (NHV) and high heating value (HHV) were found to be between 16.157 and 18.483 MJ/kg. According to the findings, agricultural residues are excellent substrates for the generation of solid fuel. The energy values of biomass samples might also be calculated using the empirical formulae based on their nearby characteristics.

“…Microwaves are currently used as sources of relatively high energy, in addition to heating food, mainly in technological processes [28][29][30]. In this section we present the application of microwaves to selected ceramic materials in order to obtain an efficient and cheap source of heating for living and utility areas.…”

The sustainability of human civilization depends largely on green energy management. This work represents one way to achieve this goal. The work is devoted to converting microwave radiation to heat. The article analyses different ways of heating residential and utility areas. Materials suitable for converting microwave radiation to heat from ceramic composites, concretes, fire clays, and bauxite with water glass are enclosed. For all materials we have measured DTA/TG (Differential Thermal Analysis/Thermogravimetric Analysis) curves, XRD (X-Ray Diffraction) patterns, chemical composition of samples, the specific heat capacity c p [J/kg.K], thermal conductivity k [W/m.K] and diffusivity α [m 2 /s -1 ]. The cooling curves of these materials after microwave heating are characterized in detail. The paper also presents a description and construction of a microwave reactor together with the parameters of the living space heating.Sustainability 2020, 12, 55 2 of 15 and oceans or the environment. The most suitable sources of this origin for heating modern homes are solar energy and energy from biomass. Wind energy is less advantageous; it can rather attract enthusiasts but its potential for family houses is not so great simply because such types need an open environment exposed to appropriate weather conditions. However, as mentioned, placing an object in such an environment increases the heat loss. The solution would be expensive and complicated, which would not pay off. Solar energy, on the other hand, is useable with a good potential in almost every family house or industry. The solar radiation after the impact on the surface area creates values from 1000 to 1250 kWh per year, thus using a photovoltaic panel or solar collectors can heat a household. Photovoltaic panels in the form of a sunroof have also entered the market, making use of two functions. There are also various collectors-window or wall. The window collector has a thickness of 20 to 30 cm and corresponds to a double window. Heat accumulated in the cavity is then consequently transferred to the storage tank by gravity or by a fan.Radiation heat has already been used for many centuries. A typical conventional heat is supplied, for instance, by a radiator or a typical electric heater (convector), through heating the air in its neighbourhood. At their surface temperature of 90 • C, infrared panel heaters radiate at the wavelength of approximately 9 to 10 µm, which is a suitable component for the human organism, influencing the growth of organism cells and psychological comfort.Microwave electromagnetic radiation represents another very efficient method of radiation heating. As opposed to other heating methods, higher temperatures can be achieved by a dielectric heating inside the heating body instead of on its surface [16][17][18].This paper contains an experimental analysis of the physical aspects of the conversion of microwaves to heat, while ensuring the safety of such a process. Specific ceramic materials were selected and experimentally checked for such a...

“…Many current literature reports suggested the use of pyrolysis assembly, which is specifically engineered to allow biomass heating at nominated temperatures, resulting in a product named as Biochar. In contrast to composting and landfilling, Biochar can cause a significant reduction in GHG emanations and can provide potential benefits to soil in terms of nutrient support (Aziz et al,2015;Azni et al, 2019). Another more efficient way of waste byproducts management and recycling is altering these wastes into a favourable source of functional components that could be used because of their promising nutritional and functional attributes.…”

Fresh and processed fruits represent a large segment in the nutritional and functional food sector and are highly popular among the health-conscious consumers. And the food processing operations are striving to meet that increasing demand for nutritious food products. Consequently, the fast-growing fruit processing businesses across the world have been generating great quantities of waste by-products including peels, pomace, husk, pods, stems and seeds which are usually discarded as waste. Although such fruit waste by-products are rich in nutrients and some functional ingredients, the inappropriate utilization and disposal is creating huge environmental problems. Hence, effective utilization of these by-products is essential. At present small amounts of certain fruit wastes are used as fertilizer or animal feed. However, a better economical and scientific approach to benefit from such waste by-products is to use them as sources of functional and nutritional ingredients. Moreover, the notion of resource optimization from the processing wastes could be a practical step towards achieving sustainable food production systems. This review focuses on the various scientific aspects and potential approaches for the utilization of fruit processing waste by-products, with special reference to fruit peels, in the food and nutraceutical applications.
