A new financing program for advanced biofuels, renewable chemicals and biomass thermal is now law.
Minnesota takes a significant step forward in implementing a new model for biomass establishment and utilization on agricultural lands. Biogas advocates and project developers have been abuzz since EPA expanded eligible biogas transportation fuel pathways to generate cellulosic RINs.
On the biogas front, 2015 was a good year, especially when compared to activity in previous years. A bill establishing a production incentive program for advanced biofuels, renewable chemicals, and biomass heat was recently heard in the MN legislature.
Legislative proposal aims to enable commercial production of advanced biofuels, renewable chemicals, and biomass thermal energy. As the Minnesota legislature moves into the final weeks of the 2015 session here is quick rundown of the status of the Bioeconomy bill.
There is renewed interest in deploying combined heat and power (CHP) technology to improve the efficiency of the energy generation and delivery system.
Biogas energy systems can also be a source of transportation fuel in compressed natural gas vehicles. Anaerobic digesters are being co-located at cellulosic ethanol production to recover biogas from waste material and provide a source of process energy for the plant. Amanda Bilek's first column for Biomass Magazine describes the incredible potential for the deployment of biogas energy systems.
August 2014 was a good month for cellulosic fuel production in the US, maybe just not from the the source you would expect. Variations among biogas projects make it difficult to adequately assess resource potential. Biomass utilization presents a large opportunity for clean energy projects, but responsible management will be essential to assure project sustainability. Organic waste such as banana peel, coffee grounds and other food waste, will be processed in a new plant in Norway which transforms it into biogas that can be used to power Oslo’s city buses.
The contract for plant construction is assigned to Norwegian company Cambi AS – a company that has been developing technology for converting biodegradable material into renewable energy for over 20 years. The new plant will produce biogas using a method known as thermal hydrolysis, whereby raw materials such as waste or sewage sludge are boiled under both high temperatures and pressure. The plant will be able to process 50,000 tons (100,000 pounds) of food waste per year, converting it to biogas fuel for 135 municipal buses as well as enough biofertilizer for roughly 100 medium-sized local farms. The waste from the biogas production process could be used as liquid fertilizer with roughly the same nutrient content as compound fertilizer. Cambi’s Research Council funding was provided under the Large-scale Research Programme on Clean Energy for the Future (RENERGI). We will arrange to take up the operation and will interact with the residents for source segregation and the segregated waste will be transferred to OWC room by the housekeeping staff.

Liquid manure or slurry can be collected and then sprayed onto your fields with a slurry tank. Solid manure is filled into a manure spreader using any front loader with silage fork or a shovel, then you can spread it on your field. In order to produce manure, you have to supply the cows with straw, while slurry is produced by feeding them with grass or with total mixed ration. Biogas systems have been early adopters of CHP and are well positioned to benefit from an increased focus on CHP implementation.


Even though there are practical project examples, there is a still a large amount of untapped potential.
This column from Biomass Magazine provides examples of projects in the US already using biogas to fuel large fleet vehicles. However, biogas projects have not typically been associated with grassland establishment, but a recent discussion at a grassland conference makes a strong case for why that should change. The new plant designed to perform that task will be located north of Oslo and it should be in operation from next year, and it will also be used to produce nutrient-rich biofertilizer that is already sterilized and odor-free.
So far the company has designed and delivered 28 plants for converting biodegradable material into renewable energy. Cambi has worked out a hydrolysis process that yields substantially more biogas compared to conventional facilities. Combined with Oslo’s 65 biogas powered buses which are powered by biogas produced from sludge from the city’s sewage treatment plant, the local bus company will have enough biogas for at least 200 buses, or an energy equivalent of 4 million liters of diesel fuel per year. What’s more, the biogas buses run quietly”, said acting plant manager Anna-Karin Eriksson of the Oslo Municipality Waste-to-Energy Agency (EGE). The new plant will supply both liquid and solid biofertilizer in addition to a liquid concentrate. The company is also an industry partner in the Bioenergy Innovation Centre (CenBio), one of Norway’s 11 Centres for Environment-friendly Energy Research. Boone Pickens talking about natural gas on TED 2012, and these plants would be a nice addition to the bridge to an oil-free future that produces useful biofertilizer as well. We optimise the biological processes in biogas fermenters in every type of system, and with every type of substrate. It continues with the production of a large range of biogas additives, which are based purely on precisely determined requirements, and are produced specifically for the individual biogas plant, according to a unique formula. They create the basis for our customers to be able to produce maximum biogas yields with their biogas plants. Dependence between methane yield from microalgae and their lipids, carbohydrates and proteins content. Potential methane yield from proteins, carbohydrates and lipids present in various algae species calculated according to Angelidaki and Sanders (2004). Fermoso2, Barbara Rincon2, Jan Bartacek3, Rafael Borja2 and David Jeison1[1] Chemical Engineering Department, Universidad de La Frontera, Temuco, Chile[2] Instituto de la Grasa (CSIC). The slurry is also produced at the biogas plant at the rate of 100 litres of slurry per 1000 litres of your biomass processed.
The core competences are rounded off by very specific consultation expertise, excellently employees, and comprehensive analyses.
Each data point represents one algae species while the error bars show the range found in the literature. The data on proteins, carbohydrates and lipids content in algae were extracted from Becke (2007), Sialve (2009), Griffiths and Harrison (2009) and Gonzalez-Fernandez et al.

Figures (a), (b) and (c) show experimentally obtained methane yields, figures (d), (e) and (f) represent theoretical methane yield for the given algae composition calculated according to Angelidaki and Sanders (2004). IntroductionMicroalgae, the common denomination for a broad group of photosynthetic prokaryotes and eukaryotes, are characterized by an efficient conversion of the solar energy into biomass.

A mathemathical model for dynamic simulation of anaerobic digestion of complex substrates, focusing on ammonia inhibition.
Microalgae are 10 – 50 times more efficient than plants in terms of CO2 fixation (Wang et al. Chemical structure of algaenans from the fresh water algae Tetraedron minimum, Scenedesmus communis and Pediastrum boryanum.


Thus, microalgae can fix 1.83 tonnes of CO2 per 1 tonne of produced microalgae (Chisti 2007). Microalgae can be produced on non-arable areas such as lakes, oceans or deserts, thus reducing competition with food production (Mussgnug et al. This advantage is a key factor when energy supply is considered in desert zones near oceans.Some microalgae can grow under saline conditions, which strengthen the use of microalgae as feedstock for biofuel production in desert zones near the ocean when freshwater supply is not feasible. Most of current efforts to take advantage of microalgae as a source of bioenergy are directed to biodiesel production, considering the ability of certain types of microalgae to accumulate lipids under controlled culture conditions. Microalgae biodiesel produced from microalgae lipids also presents technical advantages compared to lignocellulosic biomass based biodiesel. However, the biodiesel yield from algae is rather low compared to biodiesel from lignocellulose energy (Chisti 2007; Sialve et al. During biodiesel production from microalgae, energy consumption associated with culture mixing and pumping, lipid extraction, nutrients addition, drying is of particular importance (Scott et al.
Another drawback of biodiesel process is associated with the microalgae cultivation step, as nutrient requirements are 55-111 times higher than for e.g. Under these conditions, biodiesel production from microalgae may not be energetically and environmentally sustainable (Sialve et al. Microalgae as a source of biogasBiogas production through anaerobic digestion is an established technology where a wide variety of residues can be used as substrate.
The contribution of this technology to the reduction of carbon emissions, green energy and green gas policies has generated intense interest, especially over the past decade.
Two principal drawbacks are identified when biodiesel production from microalgae is considered: high nutrients requirements for microalgae growth and low energy efficiency of biodiesel production process. Anaerobic digestion may contribute to overcome such limitations, by enabling nutrients recovery and biogas production when spent microalgae after lipid extraction is used as substrate. This is based on the fact that biogas can be used as source of renewable energy and that during anaerobic digestion process, nitrogen and phosphorus may be recovered, creating opportunities for their reuse as nutrients. If oil extracted microalgae is used as substrate in anaerobic digestion process, methane produced would have a maximum theoretical contribution of 17MJ per kilogram of gross microalgae (thermal).
If the latter thermal energy is transformed into electricity, a maximum energy yield of 5.5 MJ per kilogram of gross microalgae would be achieved (assuming a conversion efficiency of 32%). Thus, a substantial increase in energy yield could be theoretically achieved, representing a considerable contribution to biodiesel sustainability and economic feasibility.
Energy contained in biogas can be used for both anaerobic digestion and trans-esterification reactor heating. Electricity obtained via co-generation can be used for different purposes such as photobioreactor mixing, microalgae harvesting and drying (Harun et al. Another alternative to recover energy from microalgae consists of methane production from whole microalgae.
CO2 biosequestration), microalgae species not capable of accumulating lipids may be also used as feedstock. Moreover, co-digestion with other types of biomass such as solid or liquid wastes is feasible.
Anaerobic digestion of algal and microalgae biomass has been previously studied by some researches (Vergara-Ferna?ndez et al.
Figure 1B shows the energy potential of Process 2, in which whole microalgae is used as substrate in order to produce biogas. The lower operational energy demands for biogas production, compared with biodiesel together with biogas, makes Process 2 very promising for energy recovery.3.
Anaerobic digestion of microalgaeReports of the anaerobic digestion of microalgae go back to the fifties when Golueke et al.
In this early study, 0.5 m3 of biogas was obtained per volatile kg of algal biomass, with methane content 63%. This is because cell walls are hard to degrade biologically and their presence avoids contact of anaerobic bacteria with the readily degradable content of algal cells. Microalgae cell wall is composed mainly of carbohydrates and proteins which represent 30-75% and 1-37% of cell wall, respectively.
