Parameters:

  • path (str) – Path to the directory containing the ecospold1 files or path to a single file.

  • db_name (str) – Name of the database.

  • use_mp (bool, optional) – If True, uses multiprocessing to parallelize extraction of data from multiple files, by default True.

Returns:

List of dictionaries containing data from the ecospold1 files.

Return type:

list

classmethod process_allocation(exc, dataset)[source]#
classmethod process_dataset(dataset: pyecospold.model_v1.Dataset, filename: str | pathlib.Path | io.StringIO, db_name: str)[source]#
classmethod process_exchange(exc, dataset)[source]#

Process exchange.

Input groups are:

  1. Materials/fuels

  2. Electricity/Heat

  3. Services

  4. FromNature

  5. FromTechnosphere

Output groups are:

  1. Reference product

  2. Include avoided product system

  3. Allocated byproduct

  4. Waste to treatment

  5. ToNature

A single-output process will have one output group 0; A MO process will have multiple output group 2s. Output groups 1 and 3 are not used in ecoinvent.

classmethod process_exchanges(dataset)[source]#

  • db_name (str) – Name of the database.

Returns:

List of dictionaries containing data from the ecospold1 file.

Return type:
