C211 - Mainland Products Ltd, Christchurch – Canterbury Region


Summary
A motivated and enthusiastic team with good staff representation and management support identified significant savings for the Food Solutions Bromley site in the relatively short time that was available to them. By focussing on reducing product losses through improved procedures and simple housekeeping changes, the team identified and implemented an estimated $117,000/annum of savings. Additional projects were identified (with savings estimated to be $160,000/annum), but were not implemented because of the announced plant closure.

Business Profile
Huttons Kiwi Ltd, as the original participants in the Target Zero programme, operated a small goods manufacturing plant at Bromley in Christchurch. In December 1997 Huttons Kiwi Ltd merged with Top Hat Bacon to become Food Solutions Ltd, which was 70% owned by Brierley’s. In December 1998, Brierley’s sold its stake in Food Solutions to Mainland Products Ltd. As Mainland already owned a ham and bacon plant at Oamaru and concluded it was not economic to keep both plants open, the Bromley plant was scheduled for closure in the latter part of 1999.

Type of Projects
Product waste reduction.

Reasons for Projects
In response initially to pressure exerted by the local authority, the management of Food Solutions soon realised that production efficiency and quality were closely allied to environmental performance. A department by department focus on product handling procedures readily identified opportunities to reduce product losses, increasing productivity and reducing the environmental impact on the trade waste system and the landfill.

Target Zero

The Food Solutions plant has been a participant in Target Zero, a two-year sponsored cleaner production programme involving 12 companies in Christchurch and 10 in Hawkes Bay during the period 1997-1999. The programme was sponsored by the Sustainable Management Fund of the Ministry for the Environment, Meridian Energy Ltd (formerly ECNZ), and the local authority and electricity company in each area.


The Projects

De-skinning operation sausage product loss

Description

A proportion of processed sausages was disposed to the landfill because of contamination as a result of dropping onto the floor from the de-skinning machine.

A larger two-tier tray was constructed and staff educated to remove the tray before it overflows.

Environmental Benefit

Reduced disposal of meat waste to the landfill.

Other benefits

Increased product yield.

Economic Benefit

Capital cost $1,000

Savings $15,235/annum

Payback < 1 month

Sausage skin product loss

Description

A proportion of processed sausages was disposed to the landfill because of the skins unravelling as a result of the end of the skin not being adequately secured.

A simple procedural change ensuring an additional twist to the skin prevented the unravelling and consequent product loss that had been occurring.

Environmental Benefit

Reduced disposal of meat waste to landfill.

Other benefits

Increased product yield.

Economic Benefit

Capital cost None

Savings $71,100/annum

Payback Immediate

Product transfer loss

Description

A proportion of processed sausages was disposed to the landfill because sausages drop onto the floor from transfer trolleys.

By simply adding a wire mesh tray to the bottom to catch any sausages that fall, the loss of product was significantly reduced.

Environmental Benefit

Reduced disposal of meat waste to landfill.

Other benefits

Increased product yield.

Economic Benefit

Capital cost $2,000

Savings $30,470/annum

Payback < 1 month

Ham loss

Description

The Langen machine tumbles ham with brine, but opens before all product has settled, spilling 70-100 kg of ham/day.

Installing a PLC to delay opening until mixture settled will eliminate the loss of valuable product.

Environmental Benefit

Reduced disposal of meat waste to landfill.

Other benefits

Increased product yield.

Economic Benefit

Capital cost $30,000

Savings $61,100/annum

Payback 6 months

Sausage mince loss

Description

A proportion of sausage mince was disposed to the landfill because the bowl-cutter was over-filled and product overflowed onto the floor.

By reformulating recipes to a consistent batch size compatible with equipment capacity and training staff to take greater care to prevent loss, product losses could be reduced significantly.

Environmental Benefit

Reduced disposal of meat waste to landfill.

Other benefits

Increased product yield.

Economic Benefit

Capital cost None

Savings $75,730/annum

Payback Immediate

Product returns

Description

One cause of product returns was found to be due to pinholes in plastic webbing caused by creasing at the corners of rectangular bacon packs.

By changing the packaging dye from square to round would reduce creasing and the tendency to form pinholes in the vacuum packs.

Environmental Benefit

Reduced disposal of meat waste to landfill.

Other benefits

Increased product yield.

Economic Benefit

Capital cost $2,000

Savings $23,230/annum

Payback 1 month
