Energy to Bioenergy Advantages & Disadvantages

Bioenergy Advantages & Disadvantages

Energy is the basic requirement of development, and it is also needed by the existence in almost every aspect of society in the world. As presently the utilization of conventional energy sources can yield a series of problems because of their non-renewable nature. Unfortunately, the world energy consumption depends heavily (80%) upon fossil fuels. Another reason is the utilization of traditional fossil fuels can also be polluting sources that accelerate global warming & climate change, such as the increase of greenhouse gases and of carbon dioxide. The usage of energy to bioenergy advantages & disadvantages is the Solution to present and future problems related to energy utilization and generation.
Bioenergy, is the powerful renewable substitution of fossil fuel, to meet the growth of the world population, mitigate global warming and safeguard energy security. In this Blog/Article few methods will discuss how much bioenergy advantages & disadvantages are helpful in current energy consumption practices.

What is Bioenergy

In its simplest form, the energy came from biomass or can produce biologically is known as Bioenergy.

Prospects of Bioenergy advantages & disadvantages

According to (International Energy Agency, 2018), bioenergy was responsible for half of all renewable energy consumed in 2017, proving four times the greater contribution of solar and wind energy combined.Bioenergy features prominently in most recent scenarios for addressing climate change. A key factor is a fact that the regulations in many countries treat biomass as a zero carbon fuel under carbon pricing regimes and for setting climate targets. The development of bioenergy will also be shaped by the presence of competing energy resources and technologies for meeting policy goals such as energy security improvement and climate change mitigation. An important feature of bioenergy regarding climate mitigation option is that it requires land for biomass feedstock cultivation. Land can be used for mitigation of climate change in two steps By enhancing the land’s biospheric carbon (C) stocks (soils and standing biomass) and thereby withdrawing CO2 from the atmosphere. By supplying biomass as a substitute for fossil-based fuels and other products and thereby reducing the emissions of fossil CO2 to the atmosphere. Biomass provides a diverse source of energy, potentially improving energy security as an alternate of oil and natural gas. The usage of domestic bioenergy resources would generally contribute to the diversification of the energy mix. There are few types of disadvantages also which need to be highlighted. But in this blog we just try to sum up the entire v view related to the Bioenergy advantages & disadvantages. Lets understand and try to mitigate these prospects of Bioenergy for future.

water & Soil

The effects of bioenergy production on water quantity are mainly through the potential water consumption of bioenergy crops and conversion of land use. The soil erosion is also triggered in three main pathways corn acreage expansion, residue removal, and land use change. Both soil and water are the main factors in the generation and production of Bioenergy. Increasing energy mix into bioenergy will affect the quantity, quality, and fertility directly. A significant water quality concern with respect to increasing cultivation of bioenergy crops is nutrient pollution resulting from surface runoff and infiltration to groundwater. Soil erosion, a very common problem, is also a major point of concern in the bioenergy production, because erosion diminishes soil quality and thereby reduces the productivity of natural and agricultural ecosystems.

GHG Emissions

Bioenergy processes can act very differently with regard to GHG emissions. Appreciating where bioenergy can have the greatest impact on GHG emissions reduction relies on both an understanding of the emissions resulting from different bioenergy routes and the importance of bioenergy in reducing emissions in a particular sector. Reduction of emissions like GHG is one of the most important terms considered in bioenergy production.
Among the GHGs, CO2 and N2O are two primary components because of their large quantity and multi approaches to production. One of the examples to mitigate is corn cultivation needs much more fertilizer compared with other crops, especially the nitrogen fertilizer,in the soil denitrification process, aggravating N2O emission directly. The other aspect is CO2 emissions resulting from the direct use of biofuels are far less than the utilization of fossil fuel, which has been proven by many studies.

Biodiversity & Ecosystems

Biodiversity is the main factor related to food production and ecosystem services The impact of biofuel production on biodiversity depends on the initial land use condition, the type of bioenergy production system, and the landscape configuration. Forestry bioenergy advantages & disadvantages can give climate benefits over the next fifty years under 3 terms of conditions: First, when the source of the biomass is waste left over from other operations, Secondly when the goal of the biomass removal is improving the ecosystem through, for example, wildfire risk reduction and last when biomass is grown on land with low carbon stocks that would otherwise remain unused. These few highlighted implications can be the few solutions to improve and protect our Biodiversity and ecosystems.

Environmental function of bioenergy advantages

Climate change is altering rainfall patterns while water transpiration and evaporation will be increased by
rising temperatures. The net effect of this is not easy to predict, and large variations can be expected in regions of the world. The production of bioenergy will be a best option to mitigate the rainfall patterns changed consequences. Biodiversity loss may also occur indirectly, such as when productive land use displaced by energy crops is re-established by converting natural ecosystems into croplands or pastures elsewhere. A bioenergy chain, or route, consists of a series of conversion steps by which a raw biomass feedstock is transformed into a final energy product (heat, electricity, or transport biofuel). There are many potential bioenergy chains as a result of the wide range of raw biomass feedstocks (wood, grass, oil, starch, fat, etc.). Biomass-based power plants. The heat produced by direct biomass combustion in a boiler can be used to generate electricity via a steam turbine or engine. From these turbines and engines the remaining char can be used as a Carbon neutral for Environment.

Different generations of Feedstock

There are three different ranges of the Feedstock to generate biofuels. First Bioethanol from sugar and starch crops, Second Bioethanol from lignocellulosic feedstocks and third is Biofuels from algae. The by-products obtained from these feedstocks Advanced biofuels with properties closer to gasoline and diesel. such as syndiesel or renewable diesel, which could be blended at much higher levels. They can be used in conventional vehicles to completely displace fossil fuels. These all types of feedstocks can provide both intermediate and final products, i.e. food, feed, chemicals, and materials. They can produce more than one product, each with an existing (or shortly expected) market of acceptable volumes and prices. These are are sustainable: maximising economics, minimising
environmental impacts, replacing fossil fuel, while taking socio-economic aspects into account.

Sawdust from Waste to Wealth

Sawdust from Waste to Wealth

The use of biomass fuel such as composite briquettes of sawdust becomes a good source of renewable energy for household cooking and space heating. The business practice will be greatly beneficial for both economy and environment. The investigative analysis of sawdust from waste to Wealth is based on conversion of by products. Mainly from agriculture, coal dust and waste from wood into high energy valued briquettes for heating and cooking.

Waste into Wealth!

In many countries Sawdust is often burnt off or disposed at sites nearby or in sawmills thus causing heat generation uncontrolled and wastage of energy. The issue might be raised to how to best utilize this waste in an eco-efficient way. Furthermore, the production of these biomass briquettes also provides income to the enterprises that took part in the production and selling of these briquettes. In this way, maximum exploitation can achieve Sawdust from Waste to wealth while staying within the community rather than being exported for foreigners or foreign dealers. Usually, sawdust used as a fuel by direct combustion is not an efficient source of energy as compared with crude oil. Currently, biomass can be transformed into numerous forms of energy as an alternative to oil and coal by means of chemical, thermochemical and biological processes.

Sources of Sawdust

Furniture manufacturing and wood processing undergo through several stages start from ripping raw timber to required sizes and parts, transportable dimensions, shaping, polishing and assemblage. At different steps, a sizeable quantity of waste generated in form of large off-cuts, cuts, chips and fine graded sawdust. Another source is the forestry and agricultural residues.

Method of converting Sawdust in charcoal Briquette

To improve the features of forestry and agricultural residues of biomass one applicable method is charcoal briquettes. In this technique loose biomass is densified into the briquettes for better storage and handling characteristics. Also for improvement in the volumetric calorific values. In developing countries where large amount of sawdust and agricultural waste are readily available. An appropriate technology of briquettes production could enhance the bioenergy potential.

Now let’s start with few steps to understand the conversion of sawdust into charcoal briquettes.

Collection of Sawdust

Site visits and questionnaires will help to collect the data regarding the quantification of sawdust from furniture markets, sawmills, or other targeted sites. The Polyethylene bags can be used to fill with sawdust. After this clean the sawdust with the help of magnets to get rid of tiny metal particles. After proper drying with the help of sunlight. The sawdust is ready for any type of treatment.

Collection of sawdust

Carbonization of Sawdust

This is the main and simple step to convert sawdust into char. For this purpose just take a large drum and after cleaning this drum making small holes in the drum for limited supply of oxygen. Put Sawdust into the drum and ignite it with matchbox. This takes 3 to 4 hrs for complete carbonization. After this take the char out of the drum. Then introduce starch as a binding agent. It will help to give them any acquired shape. After this immediately put the feed(char+ starch) into the briquetting machine as shown.

2 step carbonization Pyrolysis and BRIQUETTE Machine
Drum & Briquette Machine

Binding agent

The starch was used as a binding agent. Starch is a carbohydrate mainly composed of glucose. The starch produced through the enzymatic physical and chemical transformation. For the preparation of binding agent add 150gram of flour with 1000ml of water in the container. Put this container on the stove and stirred it continuously with the help of spoon until it became thick and yellowish in color. The resultant product was starch. Put this starch into the char and mix it uniformly to get the slug-like form of char and binding agent.

Briquette machine

The machine was modified in the locally wood workshop with main parts main frame which was made of wood, molding unit, safety block and 2 hp motor. The prepared feed made from char and starch as a binding agent in the form of a lump. The modified machine as it was highly suitable and easily locally available all over the globe for the production of the briquettes.  As the char and starch mixed together became the agglomeration form. The machine with the 2HP motor can easily operate to form the cylindrical shaped charcoal briquettes. The motor and molding unit joined with the rotary wheel. The rotary wheel moves the extruder to uniform mixing and compression of feed towards mold. The feed was charged with the help of Hooper at the input section. The feed passes through the extruder and turned into the cylindrical shaped briquettes.

Final product characteristics

The collected waste from different furniture markets was gathered and charcoal briquettes were produced. The cylindrical shape of briquettes made them easy to handle, store and use. The briquettes were packed in the 40kg polyethylene bag for storage purposes. The cylindrical briquettes have a good shutter index value. For the sake of business, the transportation of briquettes may become very easy as these were less in weight as compared to the traditionally used. The charcoal briquettes can be transported into huge amounts as of the same truck can load and transport the charcoal lesser in quantity.

Burning of Briquettes from Sawdust
Final Charcoal Briquettes

Feasibility

The biomass residue readily available in different forms all over the world. These residues are agricultural or forestry-based can be used to form the same type of charcoal briquettes. As the cellulosic properties of different biomass residues are almost same. The starch can be used which did not deflect the damaging the calorific values or heating values. Thus providing the broad spectrum to be performed on the other types of residues. The modified boilers can use these charcoal briquettes as the feed emits less smoke and reduced Greenhouse gases. The production of briquettes from indigenous resources made them highly attractive for the competing energy depict as well as business concerns for micro level enterprises. The amount of sawdust used and no of briquettes produced sustainably fulfilling all postulates of Integrated solid waste management.

Operational Cost & Profit

The fixed cost and variable cost show the operational cost per day for the production of the briquettes per tonne was PKR 25,000 and profit range from 40,000 to 42,000 PKR. This shows the real value of Sawdust from Waste to Wealth.

Conclusion

The daily earnings potential on profit based on the daily operational cost is PKR 700 to PKR 800 with the existing deigned briquettes facilities. An individual initiative of charcoal briquette production by utilizing Sawdust from Waste to Wealth as a profitable source of income. A similar technology can set up in other countries could play a vital role in recovery of useable materials from municipal waste stream. This helped to eliminate poverty alleviation in rural parts of the world for the improvement of livelihood.
