Biomass Waste

In recent years, research has shown the advisability of seeking new types of biofuel. It has been shown that apart from one-component fuel, it is also advisable to use mixtures composed of basic raw materials. These mixtures may have a favourable effect upon the overall recovery of such fuels. This paper focuses upon options for the energy use of various mixtures of biomass waste. Biomass waste originates from primary agricultural production and countryside maintenance. This mainly consists of plant residues, i.e. straw and hay. Pellets were made using the given biomass. The pellets were prepared by mixing plant residues with spruce shavings as well as from pure materials, i.e. wheat straw, hay and sawdust. Individual types of biomass were mixed in various ratios: 50% wheat straw + 50% hay, 50% wheat straw + 50% sawdust, 50% hay + 50% sawdust, 33% wheat straw + 33% hay + 33% sawdust. The following basic parameters of the prepared samples were monitored: humidity, calorific value and ash content. These parameters influence the environmental as well as economic aspects of options for using these plant residues as fuel. It was discovered during the tests that the highest calorific value was achieved using a sample of biomass prepared by mixing 50% straw and 50% hay. The highest humidity was found in a sample of sawdust and the highest ash content in a sample prepared by mixing 50% straw and 50% hay.

AbstractThe aim of the study was to assess the selected physical characteristics of the briquettes of English ryegrass waste biomass and its mixtures with waste components from the agri-food industry: pea husks and oat middlings. The raw materials used for the tests are characterized by high calorific value and low ash content. Among the tested raw materials, the most favorable values were recorded for oat middlings in this respect. The produced briquettes were characterized by high volumetric density and very diverse mechanical durability. At the same time, the results of the tests on the mechanical durability of briquettes indicated that the use of components of ryegrass mixtures selected for testing brought unsatisfactory results, as compared to other analyzed physical and energy features.

This paper presents a method of sorption using peat for elimination of emergency spills of crude oil and petroleum products and the possibility of energy use of oil-saturated peat. The results of assessment of the sorbent capacity of peat are presented, with waste motor oil and diesel fuel chosen as petroleum products. Natural peat has been found to possess sorption properties in relation to petroleum products. The sorbent capacity of peat can be observed from the first minutes of contact with motor oil and diesel fuel, and significantly depends on their viscosity. For the evaluation of thermal properties of peat saturated with petroleum products, experimental studies have been conducted on determination of moisture and ash content of as-fired fuel. It is shown that adsorbed oil increases the moisture and ash content of peat in comparison with the initial sample. Therefore, when intended for energy use, peat saturated with petroleum products is to be subjected to additional drying. Simulation of net calorific value has been performed based on the calorific values of peat and petroleum products with different ratios of petroleum product content in peat and for a saturated peat sample. The obtained results are compared with those of experiments conducted in a calorimetric bomb and recalculated for net calorific value. A satisfactory discrepancy is obtained, which amounts to about 12%. Options have been considered providing for combustion of saturated peat as fuel (burnt per se and combined with a solid fuel) and processing it to produce liquid, gaseous and solid fuels. Peat can be used to solve environmental problems of elimination of emergency spills of crude oil and petroleum products and as an additional resource in solving the problem of finding affordable energy.

Biomass Pellet

Solid Waste Processing Technology at the Source (TOSS) is an alternative method in processing organic and biomass waste on a communal scale. The processing of organic and biomass waste material is carried out in three stages of the process: biodrying which utilizes the aerobic activity of microorganisms; chopping which is intended to refine the material, and pelletization to compact the material into biomass pellets. The biodrying process in bamboo boxes is able to reduce the water content in organic and biomass waste within 4-5 days. Sorting of non-organic materials can be done at an early stage before or after the biodrying process. Sorting is required before chopping and pelletizing process to avoid unnecessary machine break down. The biomass pellet which is the final product has a diameter of about 10 mm with a length between 10-40 mm, a calorific value between 3000-4000 kcal/kg, and a moisture content of up to 15%. Compared to coal, biomass pellets tend to have higher volatile and ash content, while lower ash and sulfur content.

The construction sector in Costa Rica produces approximately 100 kg per square meter of residues, of which wood waste comprises 30%. Utilization of these wastes is still limited, but options are being sought and biomass is one of them. The aim of this work was to evaluate the characteristics of biomass produced from wood waste from construction, its energy potential, and its appropriateness for pellet manufacturing by determining its energy, physical, and mechanical characteristics. It was found that wood waste from construction is composed of different species with densities below 0.5 g/cm3, 26% moisture content, and 10% ash content; contamination with cement and nails can reach 6%. The process of pellet manufacturing can adapt adequately to using wood waste from construction, with an efficiency or yielding of 33%. Pellets presented a calorific value of 19573 kJ/kg, a bulk density of 1.25 g/cm3, an apparent density of 700 kg/m3, a failure force in compression of 467 N, and durability of 94.28%. According to different standards, the results obtained for biomass from wood waste are within the range established for pellet quality; therefore, wood waste from construction can be used to produce pellets, despite the disadvantage of it presenting high ash content.
