Division Applicability

The level of detail and the degree of formalisation of the EMS will generally be related to the nature, scale and complexity of the installation, and the range of environmental impacts it may have.

BAT 2. In order to increase resource efficiency and to reduce emissions, BAT is to establish, maintain and regularly review (including when a significant change occurs) an inventory of water, energy and raw materials consumption as well as of waste water and waste gas streams, as part of the environmental management system (see BAT 1), that incorporates all of the following features:

1. I..

   Information about the food, drink and milk production processes, including:

   1. (a)

      simplified process flow sheets that show the origin of the emissions;

   2. (b)

      descriptions of process-integrated techniques and waste water/waste gas treatment techniques to prevent or reduce emissions, including their performance.

2. II..

   Information about water consumption and usage (e.g. flow diagrams and water mass balances), and identification of actions to reduce water consumption and waste water volume (see BAT 7).

3. III..

   Information about the quantity and characteristics of the waste water streams, such as:

   1. (a)

      average values and variability of flow, pH and temperature;

   2. (b)

      average concentration and load values of relevant pollutants/parameters (e.g. TOC or COD, nitrogen species, phosphorus, chloride, conductivity) and their variability.

4. IV..

   Information about the characteristics of the waste gas streams, such as:

   1. (a)

      average values and variability of flow and temperature;

   2. (b)

      average concentration and load values of relevant pollutants/parameters (e.g. dust, TVOC, CO, NO_X, SO_X) and their variability;

   3. (c)

      presence of other substances that may affect the waste gas treatment system or plant safety (e.g. oxygen, water vapour, dust).

5. V..

   Information about energy consumption and usage, the quantity of raw materials used, as well as the quantity and characteristics of residues generated, and identification of actions for continuous improvement of resource efficiency (see for example BAT 6 and BAT 10).

6. VI..

   Identification and implementation of an appropriate monitoring strategy with the aim of increasing resource efficiency, taking into account energy, water and raw materials consumption. Monitoring can include direct measurements, calculations or recording with an appropriate frequency. The monitoring is broken down at the most appropriate level (e.g. at process or plant/installation level).
