“…As observed, electricity generation doubled in two decades, demonstrating this energy source as an interesting way to contribute, among other renewable energies, to the sustainable development of Africa. Indeed, interesting work has been carried out regarding the use of local biomass in boilers, as in the case of Cameroon [8].

The global energy scenario is becoming a vital aspect of the sustainable economic development of regions and countries. Current changes in energy production, mainly due to scarcity and geopolitical factors, have proven the need for changes in energy distribution towards a lower energy dependence. Moreover, a considerable amount of biomass waste is generated in many regions, because of agro-industrial activities, whose management could contribute to energy production. The aim of this work was to study the optimization of the combustion process in a biomass stove by using different raw materials as fuels, such as pine, poplar, and plum tree pellets. For that purpose, power, excess air, and biomass content were optimized, among other parameters, and exhaust gases were analyzed with a Testo 335 analyzer, while temperatures were recorded with temperature probes. In conclusion, high yields were found for the optimized parameters of the studied biomass products (ranging from 91.1% for poplar pellets to 92.34% for pine pellets), making these three biomass fuels suitable for combustion in the abovementioned stove. Also, increasing biomass flow by 25% in the stove contributed to a higher efficiency of the process, especially in the case of plum tree pellets.

“…Solid biomass has gained popularity in recent decades due to its ability to serve as a renewable source of energy and as an intermediate product for biomass refineries, which produce a wide range of high-value goods in established manufacturing networks. Power plants are enhancing simultaneous combustion and dedicated burning of biomass fuel to boost fuel versatility and lower greenhouse gas pollution (1) , (2) . With the need to phase out the use of fossil fuels, biomass has been identified as a potential alternative (3) .…”

Objectives: In metropolitan regions, management of solid wastes continues to be the main challenge. One of them is garden waste management. Garden waste generated in cities is either recycled into fertilizers or dumped on landfills, polluting the land. This study intends to discover sustainable waste management options for garden waste and to achieve a shift in energy from petroleum to renewable sources such as biomass, which can minimize emission of contaminants in the atmosphere. Methods: The pelletization method of managing garden waste was examined in this study. The garden waste including Palm, Jackfruit, and Ashoka leaves was collected separately from the college yard. Pelletization of these leaves was carried out after pretreatment and pulverization. The mechanical, physiochemical, and thermal characteristics of pellets were studied using several analytical techniques such as Thermogravimetric Analysis (TGA), proximate analysis, Energy dispersive spectroscopy (EDS) and scanning electron microscopy (SEM). Findings: The calorific value for pellets made from palm, Jackfruit, and Ashoka leaves was 3414.46 kcal/kg, 3304.02 kcal/kg, and 3833.88 kcal/kg, respectively. These values are reminiscent to those for sub-bituminous coal, lignite, and peat. Additionally, the very low levels of nitrogen and sulphur indicate a lower threat of contaminants in the air. Pellets have an over 90 percent impact resistance and durability , thus signifies resistance to damage and are simple to handle, store, and transport. The results of analyses indicate that pellets made from palm, jackfruit, and Ashoka leaves can be bonded strongly and display the appropriate thermochemical behavior to be used as biofuels. Novelty and applications: The pelleting of specifically Palm, Jackfruit, and Ashoka leaves has not been explored for biofuel use. The pellets generated can be used in boilers, reactors, and other combustion units along with coal to generate revenue and reduce air pollution to some extent.

“…During combustion, approximately 80% of the initial biofuel is converted into volatile products [24]. Likewise, the use of small-scale stoves has increased as an energy alternative using different types of pellets [25]. However, certain conditions are required for combustion to be completed, such as air supply, high temperatures, prolonged residence time, and a complete mixture of fuel components [26]; sometimes, it is difficult to guarantee with these stoves used.…”

Influence of Varieties and Organic Fertilizer in the Elaboration of a New Poplar-Straw Pellet and Its Emissions in a Domestic Boiler

Pollutants resulting from domestic combustion would have harmful effects on public health, causing disturbances in the atmosphere chemistry and the climate. In this work, the emissions from the combustion of pellets made of 80% poplar (organically fertilized) and 20% cereal straw (Triticum aestivum) have been analysed. Poplar wood from I-214 and AF-8 clones was obtained from fertilized and non-fertilized plots (CONTROL). Dairy wastewater treatment (MUD) and dehydrated sewage sludge (BIOSOLIDS) were the fertilizers employed. BIOSOLIDS-I214 pellets had lower quality standards, so its combustion was omitted. A flue gas sample was sampled together with the particles emitted. The I-214 MUD sample had the highest emitted CO value (1505 mg/MJ). Regarding HCl emission factors, there was a homogeneity in the results linked with the Cl content present in the raw material. A higher particle emission was associated with pellets with higher ash content. Particles were composed mainly for elemental carbon (26–80 mg/MJ), except I-214 MUD. I-214 pellets had the indicators of incomplete combustion and, therefore, major contaminants emission and major environmental impact. Thus, both the poplar clone and the organic fertilizer influenced the parameters and emissions analysed. Therefore, special attention must be paid to both characteristics.
