Biomethane per km² and per person

The gas is where the people are not

Plate with three municipal maps of São Paulo and a chart. The first shows biomethane per km² in greens, darker in the north and centre of the state. The second shows biomethane per inhabitant, from cream to dark brown: the interior is dark and Greater São Paulo, the coast and the Ribeira Valley are pale; a callout shows the capital at 0.013 m³ per inhabitant per day. The third shows municipalities in four shades of green by the quarter of the state’s potential they belong to: 25 municipalities in the first quarter, 43 in the second, 80 in the third and 470 in the last. The chart is the concentration curve of the potential, with points at 25, 68 and 148 municipalities. In the panel, bars show the six municipalities with the highest potential per km², led by Ariranha. — Fig. 055 São Paulo State (SP) EPSG:4674 Source: CP2B (Unicamp), IBGE

São Paulo’s residues could yield 16.9 million m³ of biomethane a day at the accessible level of the CP2B method. Divided by the population, that is 0.38 m³ per person per day. But the gas does not live where people live. Per km², the potential is densest in the sugarcane north: Ariranha reaches 1,326 m³ a day for each km². Per inhabitant, the leaders are small municipalities full of cane, such as Borá, with 41 m³ per person per day, while the capital, with the largest urban potential, stands at 0.013. The potential is also concentrated: 25 municipalities hold a quarter of the total, 68 hold half and 148 three quarters. Plate 050 shows how much each municipality has; this one shows how much that weighs on the ground and per person. First plate of the collection “Biogas on the ground”.

Beyond sugarcane

Without the cane, maize, poultry and the city appear

Map of São Paulo state with municipalities coloured by their largest biomethane source leaving out sugarcane: golden yellow for maize and soy straw, which dominates the south and south-west; dark blue for organic waste and pruning, covering Greater São Paulo, the coast and the Paraíba Valley and dotted across the west; clay red for poultry, in the centre and north; plum for cattle; brown for coffee, in the north-east; orange for orange bagasse, in the centre; pink for pigs; and light blue for sewage sludge, in Taubaté only. Callouts point to Bastos, with 73,000 m³ a day from poultry farms, and Itapeva, with 72,000 from maize and soy straw. In the panel, the legend gives how many municipalities each source leads and how much biomethane it adds up to in the state, and bars show the six municipalities with the most biomethane outside cane. — Fig. 056 São Paulo State (SP) EPSG:4674 Source: CP2B (Unicamp), IBGE

Sugarcane is the largest biomethane source in 370 of São Paulo’s municipalities and accounts for 82% of the state’s potential. The other 18%, 3.09 million m³ a day, draw a different map. With cane removed, maize and soy straw leads in 192 municipalities, scattered across the west and unbroken in the south and south-west, from Itapeva to Itapetininga; organic waste and tree pruning lead in 174, from Greater São Paulo to the Paraíba Valley and the interior’s mid-sized towns; poultry farms lead in 170, mostly in the centre and north of the state, from Bastos to Mococa. Dairy and feedlot cattle lead in 48 municipalities, coffee in 16, oranges in 13. The capital has the largest non-cane potential, 144,000 m³ a day, from waste and sewage; in the interior, the largest is Bastos, with 73,000, from its poultry farms.

Biomethane and gas pipelines

Countryside gas lies far from the pipe

Map of São Paulo state with municipalities in greens by biomethane potential, darker in the north and centre. On top, transmission pipelines in plum, with delivery points, along an axis that enters from the west, crosses the centre to Campinas and continues to the capital, the coast and the Paraíba Valley, and distribution networks in ochre, dense around Campinas, Sorocaba and Greater São Paulo. The north, the greenest part, has no pipeline. A callout points to Guaíra, 150 km from the nearest pipeline, with the state’s largest potential: 333,000 m³ a day. In the panel, bars show the share of the potential within 10 km, 10 to 25, 25 to 50 and over 50 km from a pipeline. — Fig. 057 São Paulo State (SP) EPSG:4674 Source: CP2B (Unicamp), EPE, IBGE

Biomethane is renewable natural gas: to reach its users it needs a pipeline, or a lorry. In São Paulo, transmission pipelines add up to 1,892 km, along an axis that comes from Mato Grosso do Sul on the Gasbol, passes Campinas and runs down to the capital and the Paraíba Valley; the distribution networks of Comgás, Gás Brasiliano and Naturgy cluster around it. The potential does not. Measured from the centre of each municipality to the nearest pipeline, 55% of the state’s possible biomethane lies over 50 km from a pipe; only 18% lies within 10 km, in 156 municipalities home to 32 million people. Guaíra, the state’s largest potential at 333,000 m³ a day, is 150 km from the nearest pipeline; Morro Agudo, the second, 103 km. The sugarcane north is a gas field without a pipe.

Biomethane and the power grid

The wire reaches closer than the pipe

Map of São Paulo state with municipalities in greens by biomethane potential, darker in the north and centre. On top, basic-grid transmission lines in ochre (up to 230 kV), clay (345 and 440 kV) and plum (500 kV or more) cross the state in every direction, densest from the north-west to the capital; black dots mark substations. A callout points to Valparaíso, 52 km from the nearest substation, with 197,000 m³ a day of potential. In the panel, two sets of bars show the share of the potential by distance to a line and to a substation. — Fig. 058 São Paulo State (SP) EPSG:4674 Source: CP2B (Unicamp), EPE, IBGE

Where there is no pipeline, biogas can become electricity on the spot and leave by wire. In São Paulo, the basic grid, from 230 kV up, adds up to 19,100 km of lines and 91 substations, and covers the state far better than gas pipelines: 58% of the biomethane potential lies within 10 km of a transmission line, and only 1% over 50 km. The bottleneck is the substation, where power enters the grid: 65% of the potential lies over 25 km from one, measured from the municipality’s centre. Valparaíso, in the west, has 197,000 m³ of possible biomethane a day 2.6 km from a line, but 52 km from the nearest substation. On the previous plate, gas from the sugarcane north lay far from the pipe; here, the wire runs right over it. Fourth plate of the collection “Biogas on the ground”.

Biogas in operation

Of the potential, what has already become a plant

Map of São Paulo state with municipalities in pale greens by biomethane potential. Dark blue circles, proportional to authorised capacity, mark nine ANP biomethane plants, from Narandiba and Paraguaçu Paulista in the west to Américo Brasiliense, Piracicaba, Elias Fausto, Paulínia, Caieiras, São Paulo and Jambeiro. Clay-red rings, proportional to capacity, mark biogas distributed generation in 24 municipalities, the largest in the capital. A callout points to Piracicaba, with 130,000 m³ a day authorised, the largest capacity. In the panel, bars show each plant’s capacity and the share of biogas processed that month. — Fig. 059 São Paulo State (SP) EPSG:4674 Source: ANP, ANEEL, CP2B (Unicamp), IBGE

Of a potential of 16.9 million m³ of biomethane a day, how much has already become a plant? In April 2026, nine biomethane plants in São Paulo reported output to ANP. Together they hold 558,000 m³ a day of authorised capacity, 3.3% of the potential, and that month processed only 15% of the biogas they could treat: three of them stood near zero. The largest, Raízen and Geo’s plant in Piracicaba, has 130,000 m³ a day authorised, from vinasse and filter cake; the Caieiras landfill plant runs the most, at 45% use. In electricity, ANEEL lists 32 biogas distributed generation units in the state, with 21.9 MW, in 24 municipalities: most of it at landfills in the capital and São José dos Campos and at a mill in Narandiba; the rest, smaller, mostly from farm manure. The larger biogas power stations are on plate 028. Last plate of the collection “Biogas on the ground”.
