Biomass Lab Design Research Question: How will the amount of soil added to the pot affect the growth of the plant? Background Information: Plants gain biomass through photosynthesis which sunlight produces energy and converts carbon dioxide along with water to carbohydrates and oxygen. Plant materials such as soil and fertilizer can also be used to produce biomass and produce biofuel from the nutrients. Hypothesis:
If more soil is added to the plants pot, then more biomass will produce in the plant. Explanation:
I predict the more soil the plant has, the more biomass it will have, because if the plant has more soil it will be supplied to more nutrients to absorb. As a plant absorbs more nutrients it will grow with the amount it takes in causing more biomass to be produced. Independent Variables:
The amount of soil Dependent Variables:
The total amount of biomass produced Materials:
● Beaker
● 3 Pots
● Soil
● Basil Seeds
● Water
● An area with accessible light
● Textbook or a heavy book
● Scale
● Pencil
● Paper Towels
● Measuring Cup

1) Gather all materials and buy things as needed from a local store such as Home Depot. You will need a Beaker, a pot, soil, basil seeds, water, an area with accessible sunlight, a textbook or an heavy object, a scale, a pencil, paper towels , and a measuring cup
2) Set up a shelf or empty area in front of a window and display the pot so that the plant will have access to a sufficient amount of sunlight.
3) Fill up the each pot with the designated amount of soil. One pot will have one cup of soil.
Another will have 2 cups of soil, and the third one will have 3 cups of soil.
4) Use the eraser side of a pencil to indent three holes about 1 inch deep in the soil that forms an equilateral triangle.

Biomass Energy in Ruse Region

...GENERAL OVERVIEW - BULGARIA Current Status of Biomass Energy There exists a large potential to utilize biomass as an energy source in Bulgaria. Bulgaria has a total land area of approximately 110,000 km2, of which some 6,200,000 ha, or approximately 60 percent of the overall land area, consists of arable and agriculture lands, and 3,903,000 ha, or approximately 30 percent, is forest cover. While information regarding the use and potential of biomass has been limited, there have been recent developments through pilot projects and preliminary evaluations that do begin to highlight Bulgaria’s full potential. Next to the country’s hydro resources, biomass accounts for a sizable share of Bulgaria’s final energy consumption, approximately 3.7 percent or 409,000 toe of the calculated 10,918,000 toe total consumption (Sofia Energy Center data report). Due to the lack of reliable nationwide assessments and data, it is estimated that in practice this number is much larger. The majority of the biomass energy consumption exists mainly in the rural areas, where fuelwood, followed by the residential consumption of wood briquettes produced from forestry wastes and sawmill byproducts amount to approximately 2 million m3 per year. In addition, wastes generated from agricultural and farming activities are produced in large quantities and exploitation of these wastes can prove to be significant source for energy generation. As the land of Bulgaria is rich and fertile, farming activities...

Biofuel and Biomass

...Biomass & Biofuel Biomass & Biofuel: The Future Umaer Ahmed SBI4U-03 Badgery, J. 01/02/13 Biomass & Biofuel: The Future Biofuels are a recent development that has stemmed a great deal of research into the issue of alternative energy. The energy that we get from biofuels originally came from the sun. This solar energy was captured through photosynthesis by the plants used as feedstock (raw materials) for biofuel production, and stored in the plants’ cells. This energy-containing biomass is converted into biofuel through biochemical, chemical, and thermo chemical conversion processes. For example, ethanol, today’s largest volume of biofuel, is produced through a biochemical process. In this process, yeasts ferment sugar from starch and sugar crops into ethanol. Most ethanol is produced from sugar canes and cornstarch. Biochemical conversion techniques allow us to make use of more abundant “cellulosic” biomass sources such as grass, trees, and agricultural residues. A simpler chemical process used to produce a biofuel is the production of biodiesel. Biodiesel facilities start with vegetable oils, seed oils, or animal fats and reacts them with methanol/ethanol in the presence of a catalyst. Algae and plants can serve as a natural source of oil which refineries can convert into jet fuel or diesel fuel. Once the biomass has been converted into biofuel, the biofuel is......

...A RENEWABLE ENERGY WORLD - FUELING THE FUTURE WITH BIOMASS Malathi.N I year MBA, School of Management Sri Krishna College of Engineering and Technology, Coimbatore. ABSTRACT Concerns about the availability and long-term supply of petroleum-derived fuels have caused the search for alternative sources of energy. After a century of unprecedented growth in science, technology, and the economy, we now face tremendous challenges to our ability to fuel the future: a fluctuating oil price, a changing climate, and continued dependence on unreliable energy sources. These problems are increasingly personal, and the demand for solutions becomes increasingly urgent. The ultimate solutions will only come from fundamental innovations in science and technology. Liquid fuels will for some applications be necessary for an indefinite period of time. Therefore, defining relevant feedstocks, producing fuels from these feedstocks and the properties of these fuels are critical issues. The utilization of biomass resources assumes importance due to the soaring crude price and depleting reserves of fossil fuels coupled with the rising environmental concern. Ethanol derived from renewable ligno-cellulosic biomass of non-edible variety has been identified globally as the future solution for meeting the energy demand. Apart from fuel and energy, biomass can also be the source of large number of derivatives. Biomass can be used for fuels, power production, and products that would otherwise be......

Low Input High Diversity Biomass

...Low input high diversity biomass Paper: Carbon-Negative Biofuels from Low-Input High-Diversity Grassland Biomass Author(s): Tilman, David; Hill, Jason; Lehman, Clarence Source: SCIENCE  Volume: 314   Issue: 5805   Pages: 1598-1600   DOI: 10.1126/science.1133306   Published: DEC 8 2006 Times Cited: 532 (from Web of Science) Due to the growing demand of energy needs in combination with global warming and the greenhouse gas emissions we have to develop a sustainable way of producing energy. One of the options for sustainable energy are biofuels. Most of these biofuels are produced on fertile lands that are in competition with food production. Beside this competition these biofuels increase the pollution form fertilizers and pesticides and threaten the biodiversity these lands. There are two major classes of biomass for biofuel production, monoculture crops and waste biomass. In the reviewed paper an experiment was performed on agriculturally degraded soil. 152 plots are planted containing various combinations of perennial herbaceous species. All plots were unfertilized and grown with low inputs. Biofuel production can be established in different ways which result in a different bioenergy. The conversion from low input high diversity(LIHD) biomass into gasoline and diesel synfuels and electricity via gasification and combined cycle technology with Fischers-Tropisch hydrocarbon synthesis ( IGCC-FT ) is the efficient one. An estimated 28.4 GJ ha-1. Due to this process 51%......

Biomass Power

...A REPORT ON INDIA’S BIOMASS POWER SECTOR SUBMITTED BY RAVI JAIN 1226109240 TO Prof. V.L.RAO IN PARTIAL FULFILLMENT OF THE COURSE BUSINESS ENVIRONMENT POLICY 17th December, 2009 GIIB, Visakhapatnam EXECUTIVE SUMMARY The total installed capacity in India is 1,50,000MW but we are facing a power deficit of around 10%. The per capita power consumption is 665 kWh and this figure is steadily increasing. To meet this increasing demand and reduce the current peak shortage, the Government has planned to double the existing capacity to 3,00,000MW over the next decade (2010-20). BIOMASS POWER SCENARIO India has a biomass availability of 150 million MT per annum which gives us a potential to install 16,000MW of biomass based power plants. But only 600MW is installed and another 600MW is under implementation. To realise this huge potential we need an investment of Rs.1,00,000 crore. Some reasons for lack of investments in Biomass sector are:   It costs around Rs.6cr/MW for a Biomass plant whereas a thermal plant requires only about Rs.4.5cr/MW. Availability of Biomass fuel with high calorific value (> 4000kcal/kg) PROMOTIONAL INCENTIVES       Accelerated Depreciation 80% in first year (Boiler and Turbine). Income Tax Holiday under Section 80 1A for 10 years. Concessional import duty; excise duty exemptions on equipments & components required for initial setting of the project. Sales tax exemption in some states. IREDA provides loans for biomass power projects.......

...English 101 Linda Martin Research Paper Jordan Hartt November 29, 2010 Slash/Burn and Chips An argument for Biomass Co-Generation Biomass co-generation is the historically proved approach to energy production. For thousands of years, the Plains Indians (then early settlers) used buffalo chips to build fires to heat their tepees (and sod huts). This was probably the first use of biomass energy in America. Early settlers learned from the Indians to heat their sod huts. After the buffalo became extinct, cow chips were used. On the plains there weren’t many trees and coal had not been discovered there, so this was a matter of survival (Whyte n.d.). Once the chips were dried in the sun they were almost odorless, and placed outside the tepees and sod huts. Western pioneers would modify their stoves to burn cow chips as they were plentiful along the cattle drive trails where the cattle were brought to the railroad cars for sale, and transporting to other areas. They compacted hay and then twisted it into twig-like bundles called cats. When the settlers started farming on the plains, they used corn stalks, corn cobs, and sunflower stalks as a source of fuel. In the United States, the first facility identified as a biomass power plant went on line in 1982. Using corn residues, rice husks, soy beans and sorghum residues, willows, switch grass, and organic waste from land fills as fuel, we could provide enough energy for all the homes in New England (Whyte n.d.).

Biomass Market in India

...BIOMASS Biomass Power Plant market in India Vishal agarwal, EnErgEtica india Vishal looks at the biomass power plant options in India and studies the financial details for each option. ven today in 2013; over 400 million people in India have no access to electricity. Because of the remoteness of much of India’s un-electrified population, renewable energy can offer an economically viable means of undoing this undone. And what better than a biomass power plant. Today, about 32% of the total primary energy use in the country is still derived from biomass and more than 70% of the country’s population depends upon it for its energy needs in some way or the other. Biomass power generation in India is an industry that attracts investments of over Rs.600 crores every year, generating more than 5000 million units of electricity and yearly employment of more than 10 million man-days in the rural areas. We can divide the biomass power plant market in India into 3 categories. Biogas based power projects Present: • The current availability of biomass in India is estimated to be approximately energetica india E 640 million metric tones per annum. This converted to cubic meters of biogas comes to 12800 million cubic meters per annum (@ 20 cubic meters of biogas per metric ton of biomass). • This should lead to both electricity and heat generation of 25600 GWh and 51200 GWh per annum respectively (@ 2 KWh of electricity and 4 KWh of heat energy per cubic meter of biogas).......

...Biomass Biomass can be garbage, wood chips, sugar-cane remnants or grass. Almost all the renewable-energy power in Florida comes from biomass, including three plants in Miami-Dade and Broward. Biomass produces 1,100 megawatts of power for Florida, according to a recent study by Navigant Consultants. About half of that comes from 11 waste-to-energy plants that process local garbage and trash and the other half is the leftovers from timber and sugar cane industries. Miami Dade’s yard waste is used to produce 77megawatt biomass facility. The County’s Resources Recovery Facility is one of the most technologically advanced waste-to-energy facilities in the world, while featuring a state-of-art air quality control system. More than 1.2 million tons of waste is processed annually, with 270,000 tons of the material being processed into a biomass fuel for export out of Miami-Dade County. The RRF is supported by three County-owned and operated landfills and three solid waste transfer stations. While receiving waste from these facilities, they will separate all aluminum and ferrous metals, from the garbage, to be sold to recycling plants. The garbage is then shredded and used to generate electricity. Their process produces a biomass fuel which is used on site to supplement the refuse derived fuel. The remaining biomass fuel is sold to cogeneration facilities in Central Florida. The ash product resulting from the waste-to-energy process is 10% of the original waste material delivered......

...Biomass: Will It Be Too Late? Susan Bergeron NSCI 280 Nicole Finley Bryant & Stratton 11/24/2011 Biomass: Will It Be Too Late There are wide assessments of biomass energy’s role in expanding our national energy supplies. There are advantages and limitations in the U. S. ethanol industry which research is being done even more than ever because of such high petroleum prices. According to Choices magazine the main advantage of ethanol is cost reducing as a gasoline additive and as a gasoline replacement using E85, which are motor fuel blends of 85% ethanol and just 15% gasoline. The problem is there are not enough corn crops to supply the gasoline demands. Other technologies are needed if bio-energy is going to expand its role in the national energy scene. Biomass processing could become profitable in the future with improvement in technology. The most important benefit of renewable energy systems is the decrease of environmental pollution and using up our current resources. However the role of biomass-ethanol in natural energy supply depends upon the success of fuel processing technologies and the energy price increase. Is there enough public knowledge to help promote and fund the need of modern technology that is needed to supply us with ethanol and biodiesel? “Biomass is a generic term for all vegetable material. It is generally a term for material derived from growing plants or from animal manure. The term modern biomass is generally used to......

My Home-Made Biomass Gasifier

...My Home-Made Biomass Gasifier Making your own gasifier is easy I've built a lot of alternative energy projects over the years. See my home-built solar panel and wind turbine pages. I've always wanted to build a wood or biomass gasifier too. Why? Well, the internal combustion engine is really an important part of our society and the basis of a lot of our transportation and portable power technology. It isn't going to be going away any time soon. I've mastered making my own electricity from the sun and wind, but that doesn't help my truck go down the road, power the lawn mower, or run my generator on cloudy, windless days. Those all have internal combustion engines, and they all need fuel to run. I finally decided it was time to master making my own fuel. Why pay the Arabs for it if I can make a working substitute myself? So what is A biomass gasifier? Basically is a chemical reactor that converts wood, or other biomass substances, into a combustible gas that can be burned for heating, cooking, or for running an internal combustion engine. This is achieved by partially combusting the biomass in the reactor, and using the heat generated to pyrolyse or thermally break down the rest of the material into volatile gasses. A well built reactor will also convert combustion byproducts like CO2 and water vapor into flammable CO and H2 by passing them over a bed of hot charcoal where they will get reduced.    Thus the gasifier converts most of the mass of the wood (or......
