PDT® Life Cycle Assessment

Obtains this PDT® digital certificate the organization that has quantified the environmental impacts of a product, process, or service through a life cycle study (Life Cycle Assessment - LCA) and provides for the initial and periodic monitoring of potential environmental impacts during the entire lifetime, as declared in the PDT® digital certificate issued in Blockchain by IQC srl

To highlight the contribution of the Company to the sustainable development, relating the informative management of the environmental performances of the own product/process/service with environmental claims and the characteristics declared in the PDT® digital certificate. The continuos and discreet detection of the revelant information allow the trackability, the evolution monitoring and the assurance of inalterability and immutability of the characteristics declared in the PDT® digital certificate in Blockchain.

The study was conducted with an LCA approach that complies withe the standards:

• UNI EN ISO 14040:2006 - Environmental Managements - Assessment of the life cycle - Principles and framework of reference
• UNI EN ISO 14044:2006 - Environmental Management - Assessment of the life cycle - Requirements and guidelines

Environmental sustainability of the sterilizer NW50 life for the hospital solid waste management by Newster System srl.

The software used for data collection is Thinkstep Gabi Professional, combined with the Database for Life Cycle Engineering. The method selected for the analysis is EF 3.0, including all the environmental categories, recommended models at midpoint, together with their indicators, units and sources.

The present analysis aims at the environmental sustainability assessment of two steps of the Newster sterilizer (NW50): the manufacturing and the end-of-life.

The NW50 has been chosen for the analysis since it is the bestselling model. 

System boundaries considered for the LCA:

• Raw materials
• Manufacturing
• End of life

• The present analysis is not referred to a specific site, therefore the transport aspects have been excluded
• The electric cables considered for the analysis are considered as 3 wire cables
• Manual operations (without a relevant electricity consumption) have been considered for the sterilizer dismantling, therefore their impact has not been quantified
• As concerns the recycling impacts of steel, cast iron, aluminium and copper fractions, we considered an environmental load due to the average energy consumption for recycling operations, derived from the scientific literature
• The components that cannot be recycled are considered suitable for the incineration at a facility for urban waste

The functional unit selected for the analysis is a NW50 sterilizer, corresponding to 2315 kg of equipment.

The present report estimated load due to the phases of manufacturing and end-of-life of the sterilizer NW50, produced by Newster System srl. Overall, the LCA proved that the main composing materials, steel and aluminium, represent the weaknesses (for the high impact due to the mining and production) but also the strenghts thanks to their recycling potential, able to balance the environmental load of the equipment manufacturing.

The results show that the environmental benefit is able to balance around 60% of the impact due to manufacturing.
