Use advice for data set The environmental impacts considered for the product stage cover the
manufacturing of raw materials used in the production as well as packaging
materials and other ancillary materials. Also, fuels used by machines, and
handling of waste formed in the production processes at the manufacturing
facilities are included in this stage. The study also considers the material
losses occurring during the manufacturing processes as well as losses during
electricity transmission.
The factory produces coated and uncoated birch plywood. Ancillary materials
and energy used in the factory have been allocated between the coated and
uncoated products since they are collected on factory level.
The products are packaged using cardboard, pallets and packaging film. The
mass of the packaging is 13.4 kg.
The electricity used in the factory is nuclear energy. The heat used in the
5 Coated Birch Plywood
factory is district heat, which is fuelled by Estply's production waste (wood
bark). Other wood waste is collected and mostly sold as input for pellets,
shaving. Co-product allocation has not been used.
The EOL scenarios are applicable to Europe.
Consumption of energy in demolition process is assumed to be negligible. It
is assumed that 100 % of the waste is collected as a wood waste and that
there is no mass loss during the use of the product. Therefore, the end-of-life
product is assumed to have the same weight as the declared product.
The product is considered to be 100 % collected for energy recovery.
Transportation distance to the closest incineration facilities is assumed to be
50 km and the transportation method is assumed as lorry, which is the most
common option.
In stage D it is assumed that in the end of life the product is used as a
substitution of virgin materials in heat and electricity production.
The efficiency of the incineration process in C3 is assumed to be 83%. 11% of
the energy goes towards electricity generation and 73% towards heat
generation (Eriksson O., et al., 2017). |
