This study proposes employing acidified digestate solid fraction (DSF) as an effective P starter fertilizer for horticulture crops. Our investigation comprised two experiments to assess the effects of acidification and different application methods (mixed vs. acidified) DSF on use efficiency root growth in Acidification (7.5 % H2SO4, ww−1) reduced pH from 9.6 1.6 increased solubility 14 59 total P. In first experiment, we observed crop-specific responses placement, with all ten crops exhibiting significantly higher uptake when DSF, compared untreated mixed soil. Notably, (carrot, onion, fennel) beans demonstrated most favorable response placement. The second experiment focused six selected crops, comparing versus rhizoboxes. Bean, pea, broccoli, carrot, onion exhibited soil surrounding placement zone, due availability that boosted early-stage crop growth. Furthermore, also its sulfur value. conclusion, can make it efficient phosphorus fertilizer. However, is worth noting has low density, processing such pelletization may be needed facilitate handling allocation a biobased Moreover, further studies are required commercial yield, vegetable nutraceutical properties, optimal rates.

Sustainable Production of Coffee Husk Pellets: Applying Circular Economy in Waste Management and Renewable Energy Production

Resources, Год журнала: 2025, Номер 14(2), С. 26 - 26

Опубликована: Янв. 31, 2025

Improper waste disposal is one of the leading causes environmental pollution, impacting soil, water, and air quality. In coffee plantations, each kilogram beans produced generates an equal amount husk, emphasizing urgent need for sustainable practices to process this residual biomass into valued products. This study aimed evaluate potential husks pellet production. Three husk types were selected with distinct chemical compositions granulometries: I (>5.3 mm), II (>2.6 mm <5.3 III (<1.77 mm). The was characterized elemental, structural, proximate composition. Pellets two knife heights (15 20 mm) assessed moisture content, density, length, mechanical resistance, which compared EN 14691-6 standard (DIN, 2012). Pelletizer productivity also evaluated. from had ash content 12.09%, exceeding <10% requirement. Other treatments met standard, category B.

A concise review of technologies for converting forest biomass to bioenergy

Journal of Technology Innovations and Energy, Год журнала: 2023, Номер 2(3), С. 10 - 36

Опубликована: Авг. 18, 2023

The use of biomass is vital in reducing the negative effects rising fossil fuel consumption. Given its quantity and diversity, forest has garnered a lot interest among many kinds biomass. This study evaluates various strategies for transforming woody waste into usable biofuels. Carbon dioxide emissions from traditional energy generation systems could be mitigated through direct utilization Low conversion rates, as well soot residues, are some problems that come up when directly using sustainability also seriously threatened by lack constant access to Co-combustion with coal pelletizing two solutions proposed this issue. potential lower process's carbon monoxide, nitrogen oxides, sulfides. article reviews discusses biochemical thermochemical mechanisms can transform variety liquid gaseous Future research cutting-edge assessment tools like life cycle assessment, exergy, etc. should investigate processes bioenergy further.

This paper presents research findings on the pelleting process of pine sawdust using bakery waste in a pelletizer. The addition (white wheat–rye bread, whole-grain rye and pumpkin bread) to had beneficial effect kinetic strength pellets obtained, an increase up approximately three percentage points. density with also increased, while bulk decreased. positive power demand It was reduced from 3.08% (at 10% white 22.18% 20% bread), compared compacting pure sawdust. In addition, all containing lower energy yield (EY) determined based heating value inputs. index by 53 Wh·kg−1 for bread. greatest reduction, other hand, 173 pellets, each case, share additives resulted decrease obtained. smallest reduction EY found when bread used as additive (from 133 Wh·kg−1).

Exploring the Potential of Perennial Nectar‐Producing Wild Plants for Pellet Combustion

Advanced Sustainable Systems, Год журнала: 2024, Номер 8(6)

Опубликована: Фев. 6, 2024

Abstract Perennial nectar‐producing wild plant species (WPS) cultivation for biogas production helps improve ecosystem services such as habitat functioning, erosion mitigation, groundwater protection, and carbon sequestration. These could be improved when WPS are harvested in late winter to produce pellets briquettes solid energy carriers heat production. This study aims gaining first insights into the use of biomass resource pellet briquette combustion with focus on two perennial common tansy ( Tanacetum vulgare L.) mugwort Artemisia vulgaris L.), biennial yellow melilot Melilotus officinalis teasel Dipsacus fullonum L.). All found economically viable combustion. The main drivers i) low costs, ii) subsidies, iii) costs due moisture contents. However, high ash contents justify need blending woody‐biomass or supplementing additives attain international standards household stoves. approach appears technically feasible providing a research field significant potential impacts. As 70% market is demanded level, public concern about legal framework alternative must overcome develop this market.

Transforming Wine By-Products into Energy: Evaluating Grape Pomace and Distillation Stillage for Biomass Pellet Production

Applied Sciences, Год журнала: 2024, Номер 14(16), С. 7313 - 7313

Опубликована: Авг. 20, 2024

The by-products of the wine industry represent a global production 10.5 to 13.1 million tons pomace annually. This study examines chemical composition and energy potential distillation stillage, evaluating their suitability for pellet within ENplus® standards. Proximate analysis, elemental calorimetric analysis were conducted on samples two collected in local Distillery Portugal. results reveal that has higher volatile matter content (62.695%) than which, however, lower ash (3.762%) fixed carbon (31.813%). Calorimetric analyses show stillage superior low heating value compared pomace, with values exceeding 19 MJ/kg. Both by-products, exceed limits (≤0.70), nitrogen (≤0.3), sulfur (≤0.04) content, presenting challenges use as high-quality fuel pellets. Combining these biomasses other materials could reduce pollutant improve efficiency. highlights need pre-treatment strategies enhance combustion. Policy support sustainable practices is essential optimize renewable sources.

Torrefied pellets have gained more commercial importance due to their excellent performance in combustion, co-firing and gasification. The present investigation provides a conceptual design for torrefied fuel production via combined torrefaction pelletization technologies with without additives. entire contains unit, grinding, preparation of pellet formulation, pelletizing, finally cooling pellets. Two scenarios, scenario 1 (pelletization biomass additives) 2 any external were tested compared. economic analysis suggests that both scenarios are profitable. Both simulated using Aspen plus™, feasibility was estimated complete cash flow base case plant 40,080 tonne/y capacity. For cases, discounted is useful tool estimating the minimal selling price as well capital investment, cost operating costs. reactor used found be most important component system. lowest generated $103.4 $105.1 per tonne at gate 2, respectively. Sensitivity shows that, among all variable costs, labor has highest influence on net value (NPV) minimum (MSP) making scenarios.
