USE BIOGAS TO SAVE ENERGY AND MONEY

 

Dati ufficiali forniti dal MiSE-DGSAIE l'anno scorso il nostro paese ha avuto bisogno di 70,3 mld mc di gas naturale (erano 74,3 mld mc nel 2019).

Quante sono le imprese agricole in Italia?

In Italia sono attive 1.630.420 aziende agricole e zootecniche di cui 209.996 con allevamento di bestiame destinato alla vendita. Nel complesso, la Superficie aziendale totale (Sat) risulta pari a 17.277.023 ettari e la Superficie agricola utilizzata (Sau) ammonta a 12.885.186 ettari (2021).

Nel 2017, le imprese agricole sono 413 mila (27,3% delle unità economiche che svolgono attività principale o secondaria nel settore agricolo), utilizzano il 65,3% della superficie agricola totale e occupano in media circa 2 addetti.Dec 2, 2019

Secondo l'Istat, in Italia ci sono 413mila imprese agricole, di cui 1 su 3 a gestione famigliare.

Quanti bovini si allevano in Italia?

In Italia si allevano 9 milioni di bovini, 9 milioni di suini, quasi 13 milioni tra ovini e caprini, 500 milioni di polli "da carne", 50 milioni di galline ovaiole, 100 milioni di conigli e centinaia di milioni di altro pollame (galline faraone, tacchini, quaglie, ecc.).

Quanti allevamenti estensivi ci sono in Italia?

Attualmente risultano aperti nel nostro Paese oltre 9 mila allevamenti avicoli — non solo polli quindi, ma anche tacchini e galline — con un numero di capi che supera i 137 milioni, cioè oltre il doppio dell'intera popolazione italiana. Nel 2019 i polli macellati in Italia sono stati 511 milioni.

Quanto guadagna un impianto di biogas?

Allora, poiché mediamente un impianto a biogas può lavorare 7.800 ore l'anno (in pratica, opera a ciclo continuo giorno e notte per 7 giorni alla settimana), un impianto a biogas fornisce ricavi pari a 2.184 euro per ogni kW di potenza.

MICRO AD PLANT INSTALLATION OF 44 KW CAN DELIVER UP TO 352,000 KWH OF ELECTRICITY AFTER A YEAR OF PRODUCTION.

MICRO ANAEROBIC BIOGAS SYSTEMS DESIGNED TO RUN ON ONLY DAIRY SLURRY

What do you need?

At least 1500 m³ liquid manure per year and about 200 m² space on your farm or a minimum of 80 cows.

How much biogas can be produced from 1kg cow dung?

Biogas from cow manure with 1 kg produced as much as 40 liters of biogas,while chicken dung with the same amount produced 70 liters. Biogas has a high energy content which is not less than the energy content of the fuel fossil. The calorific value of 1 m3 biogas is equivalent to 0.6 - 0.8 liters of kerosene

Biogas from Anaerobic Digestion

1 m3 biogas at 60% methane content converts to 6.7 kWh energy. Biogas can be combusted to produce heat alone.

How much energy is in 1kg of biogas?

This amount of methane then can be converted into energy of around 55.5 MJ/kg.

How do you calculate energy from biogas?

Electrical potential estimation was calculated with the assumption of 1 m3 biogas has a calorific value of 22 MJ, and 1 m3 methane is equal with 36 MJ. With assumption of electrical conversion efficiency of 35%, therefore 1 m3 biogas will yield 2.14 kWh (electricity) and 1 m3 methane will yield 10 kWh.

How much electricity is produced from biogas?

Each cubic meter of biogas contains the equivalent of 6 kWh of heat energy. The same volume of biogas converted to electrical power yields 2 kWh; the rest of the energy is dispersed as heat that can be reclaimed and applied to other uses.

How is Bio gas converted to electricity?

Biogas is converted to mechanical energy through an internal combustion engine. The mechanical energy rotates an electric generator which produces the electricity. Biogas engine - uses the biogas to generate mechanical energy.

How do you calculate biogas?

The gas demand can be defined on the basis of energy consumed previously. For example, 1 kg firewood then corresponds to 200 l biogas, 1 kg dried cow dung corresponds to 100 l biogas and 1 kg charcoal corresponds to 500 l biogas. The gas demand can also be defined using the daily cooking times

How much does it cost to produce 1 kg of biogas?

Biogas from cow manure with 1 kg produced as much as 40 liters of biogas,while chicken dung with the same amount produced 70 liters. Biogas has a high energy content which is not less than the energy content of the fuel fossil . The calorific value of 1 m3 biogas is equivalent to 0.6 - 0.8 liters of kerosene.

What is calorific value of biogas?

Biogas generally comprise of 55-65 % methane, 35-45 % carbon dioxide, 0.5-1.0 % hydrogen sulfide and traces of water vapor. Average calorific value of biogas is 20 MJ/m3 (4713 kcal/m3). Biogas like Liquefied Petroleum Gas (LPG) cannot be liquefied under normal temperature and pressure.

How can biogas be used to calculate electricity?

Electrical potential estimation was calculated with the assumption of 1 m3 biogas has a calorific value of 22 MJ, and 1 m3 methane is equal with 36 MJ. With assumption of electrical conversion efficiency of 35%, therefore 1 m3 biogas will yield 2.14 kWh (electricity) and 1 m3 methane will yield 10 kWh.

Is biogas cheaper than LPG?

Biogas- A 80% Cheaper Option For Cooking Than LPG.

How much electricity is produced by biogas?

Each cubic meter of biogas contains the equivalent of 6 kWh of heat energy. The same volume of biogas converted to electrical power yields 2 kWh; the rest of the energy is dispersed as heat that can be reclaimed and applied to other uses.

How much biogas is produced per day?

8 – 10 m³ biogas plant produces 1.5-2 m³ gas and 100 litres digested slurry per day using dung from 3-5 cattle or 8-12 pigs.
