The predecessor of the attempt to better systemise the bio-based input streams, is the industrial WW guide of the Better Efficiency for Industrial Sewage Treatment (BEST) project, funded by the Interreg Baltic Sea Region Programme 2014-2020 (Finnish Industrial Wastewater guide, 2022). This industrial WW guide describes the collaboration model between municipalities, water utilities and industrial enterprises. This guide also reports the legislation applied to industrial WW. The regulatory framework and the WW disposal limits are part of the questions the Industrial WW producers are subjected to as part of their interview in the WalNUT project. As part of this guide, the characteristics of industrial WW (i.e. bio-based input streams) are presented regarding:

Food industry

• Dairy industry
• Slaughterhouses and meat processing plants
• Breweries and the soft drink industry
• Potato and root vegetable processing plants
• Bakeries
• Fish processing plants

Metal industry

• Surface finishing plants
• Steel pickling plants
• Phosphating process plants
• Anodising plants
• Shipyards

Chemical industry

• Paint and coatings industry
• Rubber industry
• Explosives factory and blasting sites
• Pharmaceutical production plants
• Enzyme production plants
• Sulphuric acid production plants
• Printing ink factories

Printing industry

• Offset printing plants
• Silk-screen printing plants

Forest industry

• Pulp and paper industry

Textile and leather industry

Textile printing

• Tanneries
• Laundries

Manufacturing of mineral products

• Glassworks and fibreglass plants
• Concrete plants

Transport

• Ports
• Waste water from airports
• Energy production

Waste management

• Waste treatment plants and landfills
• Composting plants and facilities
• Biogas plants
• Sludges from septic tanks and cesspits

Services

• Hospitals
• Dental clinics

• Water of public indoor swimming pools

Construction

• Construction sites
• Remediation of contaminated soils

Other

• Laboratories
• Art workshops and hobby clubs
• Waste water from animal shelters
• Stormwater
• Sludge generated by other water utilities

This also acts as an exhaustive list for the better systemisation of bio-based input streams and their characteristics that render them potential candidates for nutrient recovery practices can be accessed in the (Finnish Industrial Wastewater guide, 2022).
