Each manufacturing site of Lonza Group maintains its waste disposal concept tailored to production, which is essential for an efficient, targeted and environmentally sound treatment and disposal of generated wastes. All manufacturing sites are dedicated to the Lonza waste reduction principles as set out in the Group EHS Policy:

AVOID > REDUCE > RECYCLE > TREAT > DISPOSE

while observing safe and environmentally sound processes and procedures.

Non-avoidable wastes are managed in a safe manner and with due environmental care according to state-of-the-art technologies. Variances in the yearly figures are dependent on total production as well as product mix and are reflecting the characteristics of the custom manufacturing business.

 

 waste generation

 

The total quantity of waste generated by Lonza in 2015 was 177 000 metric tons, of which 108 000 metric tons consisted of special (hazardous) wastes and 69 000 metric tons of non-hazardous wastes or inert materials.

NOTE: Restatement regarding 2014 HazWaste (4/29/2016): The total of 2014 hazardous waste amounted to 98 600 metric tons.

Categorization as hazardous waste or non-hazardous waste is guided by the applicable national regulations, which show some harmonization intra-regionally, though vary considerably extra-regionally (US, Canada, South America, EMEA, China, Asia, Oceania).

The volume of waste produced in both categories may be subject to substantial annual fluctuations. In particular new buildings and construction projects involving large-scale excavations or controlled deconstructions of existing buildings and installations may have a significant impact on the generation of both categories of wastes.

We some variation of the waste intensity year-on-year (waste generated per metric ton of finished goods) in the range of +/-10 %.
For year 2015 we report a hazardous waste intensity of 177 kg/t, up 11 % from 2014. (Just for comparison: the 2014 vs. 2013 change was -9 %.)

 

  waste haz categories

In the reporting year, 92 % of hazardous waste materials were incinerated, externally recycled or treated to render them non-hazardous; and 8 % went to secured landfills. Over the pastyears this is a repeated pattern for Lonza's production sites.

 

waste non-haz categories

Lonza has a specialized waste disposal concept at all its sites. Material flows are analysed and, as far as possible, waste is avoided or recycled. At some locations, including the large complex at Visp, Switzerland, Lonza operates its own waste and wastewater treatment installations for the comprehensive handling of wastes from cradle to grave. Where in-house treatment is not available, Lonza carefully selects its partners for waste transportation and treatment according to their sound performance and management in EHS terms.

Lonza ensures that the treatment and disposal of all its waste materials is conducted according to internationally accepted standards and conforms to the locally applicable regulations. The system and performance of waste managemnt at our manufacturing sites is subject to regular internal audits. Lonza proactively pursues an environmentally sound waste management.

All companies involved in the transportation, processing and final disposal of wastes are known to Lonza. Waste treatment is a matter of trust. The selection of the vendors is based on quality and EHS criteria as well as economic factors. As a matter of principle, we work only with reputable firms which comply with all legal requirements.
