- Water usage reduced by 25%
The Business Challenges:
Van Belle Nursery in Abbotsford, British Columbia, Canada, had all the components of a high-tech nursery — state-of-the-art greenhouses, a complete environmental control system, and a conveyor system. But company general manager Dave Van Belle wanted to make sure all the pieces fit into an efficient production system.
The FlowVision Solution:
Van Belle enlisted the help of FlowVision, a Colorado-based Lean and flow manufacturing services firm, to evaluate the propagating and packing process and remove waste. “It’s been a real eye-opening experience. We have improved our productivity by about one-third,” Van Belle said. “More importantly, we’re changing our culture to continually look for incremental improvements that, over time, add up.” Van Belle grows woody ornamental as liners and gallon-sized material. The nursery propagates about 99 percent of everything it ships. With the help of Lean manufacturing, the nursery is aiming for about four turns per greenhouse per year. “The whole focus is to be set up like a bedding plant grower without the bedding plant prices,” Van Belle said.
Implementation:
The nursery completely changed its propagation process without “over-mechanizing things,” he said. Flats go through a flat filler and a watering tunnel. Next, the flats are dibbled and traveled through the conveyor to awaiting employees who remove the trays and stick them. Next, the trays travel on another conveyor, are loaded onto a rolling bench, and placed in the production area of the greenhouse. “We can propagate our plants so fast now, we’re either going to have to build more greenhouses or root plants faster,” Van Belle said. “We can fill a greenhouse with flats in two weeks, but plants don’t root that quickly.” Previously, employees pre-filled the flats on the benches, rolled the benches into the greenhouse, and stuck the plants on the bench.
Results:
Only a week after changing the packing process, it was operating faster than before, Van Belle said. The rolling bench system brings the plants directly to the packing line. The new packing line allows the nursery to pack two tractor-trailers a day, which equals about 60,000 plants. Because the nursery can’t pull 60,000 plants a day, Van Belle plans to revisit and improve that process. Lean manufacturing helped the nursery increase production by 20 percent, which doesn’t reflect the whole story because the new processes were implemented in June.
Typically the nursery starts production in April. The propagation and packing are done in a third of the space before implementing Lean techniques. The nursery is using the extra space as a holding area for outbound orders. Van Belle plans to use the extra space for more production during the next year or two. Van Belle Nursery implemented other efficiencies such as keeping only a four-day supply of boxes on hand and reducing the number of warehoused containers. The nursery reduced its water use by 25 percent each year in the last two years by changing irrigation nozzle sizes and misting less often.
