In 2018, the production of electricity from biomass energy products was 54,400 gigawatt-hour (GWh), which represented 9% of all electricity produced in Brazil. The two most used natural inputs for the generation of this type of electricity were sugarcane biomass and bleach.
The information comes from the Environmental Economic Accounts for Energy: Biomass Products, released today (9) by the Brazilian Institute of Geography and Statistics (IBGE).
The sum of the production value of the four main energy products from biomass (alcohol, biodiesel, charcoal and firewood) totaled R$ 84 billion, corresponding to 0.7% of the gross value of the total production of the economy for the same year . Alcohol had the greatest weight, with 73.9% of the gross production value.
The research is the result of a cooperation between the IBGE and the Energy Research Company (EPE), with the support, in its initial stages, of the German International Cooperation Agency for Sustainable Development (GIZ GmbH), through the Ministry of Environment Environment. The study provides information on the resources and uses of biomass energy products in Brazil.
"This is an important instrument to demonstrate the flow of resources and uses of natural inputs and energy products between the environment and the economy, both in physical and monetary aspects", said, in a note, the research manager Michel Lapip .
The national production of natural energy inputs from biomass was 91.3 million in 2018. This value represents about 30% of the total primary national production of energy products in the National Energy Balance, prepared by EPE.
Among the inputs are sugarcane biomass (bagasse, molasses and sugarcane juice); firewood; the bleach; and other energy sources from biomass such as biogas, biomass and vegetable oils. The two most used were sugarcane biomass (62.2%), coming essentially from bagasse, and bleach (27%).
According to the survey, from 2015 to 2018, the average growth of natural energy inputs from biomass was 1.4%. Biodiesel production had the highest average growth in the period (10.7%), followed by bleach (6.5%) and alcohol (3.0%). Firewood also increased (0.9%).
Increased consumption of firewood
The use of firewood per capita by families showed an average growth of 3.7% from 2015 to 2018, when it reached 112.1 kg per inhabitant. Per capita consumption of alcohol by families fell 0.8% in the period, with 122.4 liters per inhabitant in 2018. "Families use alcohol and biodiesel for transport and firewood and charcoal for cooking and heating", stated Lapip.
As for the shares of participation in the use of products, the study shows that alcohol has been used more by families than by economic activities. In 2018, the participation of the first group was 82% against 18% of the second, reaching BRL 86.2 billion and BRL 18.9 billion, respectively.
On the other hand, the share of expenditure on biodiesel by economic activities was 95.6%, reaching R$16.9 billion, while families spent only R$786 million on biodiesel (4.4%).
Spending on energy products from biomass by families totaled R$90.4 billion in 2018, representing 34.5% of expenses associated with total energy products, except electricity. The research manager explained the removal of electricity from the account.
“It is an expense that we cannot separate the origin. When we use electricity in our homes, we don't know how much of it comes from hydraulic energy or wind energy, and how much comes from sugarcane bagasse,” said Lapip.
Among the products used, alcohol concentrated the largest share of these expenses. Mainly used for transport, it represented 95.3% of household expenses, reaching R$ 86.2 billion in 2018, while biodiesel represented 0.9% of household expenses, with R$ 800 million.
