Global breakdown of solid waste types in Sappi (%)

Global breakdown of "other" solid waste types in Sappi (%)

Disposal methods of solid waste (t/adt)  
 

Comment:

In SEU, on-site combustion decreased mainly to the closure of the bark boiler at Stockstadt ill which in turn increased the off-site combustion. The situation in SNA was stable, while in SSA, increased beneficiation led to a decrease in landfilled waste.

 
Specific landfilled solid waste (t/adt)
 

Comment:

Globally, there was a decreased in waste sent to landfill. However, there was an increase in SEU, due mainly to the acquisition of Rockwell Solutions and a higher amount at landfilled soil waste at Gratkorn Mill. The decrease in SNA was due a reduction of landfilled dregs at Cloquet mill and less boiler ash being sent to landfill at Westbrook Mill. The decrease in SSA was primarily because of an increase in ash sales at Ngodwana Mill.

Disposal methods of solid waste (%)

Comment:

In SEU, onsite combustion decreased mainly due to the closure of the Stockstadt Mill bark boiler which in turn increased offsite combustion. In SNA, landfilled was stable, while in SSA, levels decreased because of higher levels of benefication.

Beneficial use of solid waste (%)

Comment:

Globally, there was an increase year-on-year. SEU was stable and there was a slight increase in SNA, due to a reduction in landfill, improved sludge burning at Cloquet Mill, increased bark burning at Somerset Mill and lower offsite landfilling at Westbrook Mill. In SSA, Saiccor Mill beneficiated more ash (used in blockmaking and cement production), while Ngodwana Mill increased ash sales.

CASE STUDY

Reducing pallet wrapping film at Ehingen Mill

In 2019, at Ehingen Mill, we worked to reduce the amount of wrapping film used to cover pallets of paper for shipment. By lowering film thickness and optimising the wrapping processes in the finishing department, we have been able to decrease the amount of film used to pack paper pallets about to be shipped. Through simple measures like cutting the protective wrapping film more precisely, we save 35.4 tons of film per year and have reduced the volume of eventual waste for our customers. The new process still ensures that goods arrive at the customer safely and well protected. The initiative was the result of in-house lean updates and active brainstorming among colleagues.
