General comment on data set | The conventional process of charcoal production in rudimentary circular kilns, of the hot-tail type, with low volumetric capacity and low gravimetric yield, when compared to the industrial rectangular kilns. The production of charcoal with these types of kilns is mostly done by small and medium producers and depends on the knowledge of the carbonizer. It represents about 70% of the charcoal production system in Brazil (CGEE, 2015). One of the important characteristics of charcoal suitable for use in the steel industry is the fixed carbon content (% FC), identified in laboratory analysis. However, there is no difference in the production process of charcoal for steelmaking or domestic use. |

Data set valid until | 2027 |
Time representativeness description | The data on charcoal production are based on on-site collection in a smallholder production unit in 2017, but the use of this technology is expected for at least 10 years. All calculations were made in 2020-2021. Other processes such as forest wood and polypropylene come from the EcoInvent v3.5 database. These specific flows are not available in the ILCD database, but their use is suggested to ensure completeness of the environmentally relevant material/energy flows. |
Technological representativeness | |
Technology description including background system | Carbonization of wood in circular masonry kilns in a craft process using wood from planted forests of the species Eucalyptus Dunnii Maiden with release of gases to the atmosphere. |

Data selection and combination principles | The data is based on a Charcoal Production Unit (CPU) located in the Campos Gerais region of Paraná. | ||
Deviation from data selection and combination principles / explanations | None. | ||
Data treatment and extrapolations principles | There are no missing data other than those that were not considered within the studies and scored as suggested, according to the Qualidata Guide. | ||
Sampling procedure | The data were collected through a production unit. However, the representativeness is on a national level, since the charcoal production process is used all over Brazil. The production of charcoal with these types of kilns represents more than 70% of the charcoal production system in Brazil (CGEE, 2015), emphasizing that variations can occur depending on the raw material and the conduct of the process. | ||
