Waste-to-energy machine designed in
SolidWorks
Bouldin and Lawson cultivates a green approach with waste-to-energy machine designed in SolidWorks.
One of the country's largest horticulture machine makers blazes new trails with 3D CAD software Horticulture equipment maker Bouldin and Lawson is at the forefront of the "green" movement using SolidWorks 3D CAD software to design a series of machines that will convert household waste into biofuels and electricity

Designing the machines for the company's WastAway sister division, Bouldin and Lawson engineers have developed a system that is already converting waste for all of Warren County, Tennessee (population 38,276, according to 2000 Census figures).
The process yields a wood pulp-like substance called Fluff used for everything from construction material to park benches to potting material for plants.
Bouldin and Lawson began in 1959 as a way to automate horticulture processes so nurseries can get more plants on the shelf faster.

3D CAD software is first in industry to be highlighted in popular series renowned for clarity, humor, and gentleness.
Now the company has more than 80 different machines that automatically trim geraniums, pot and plant zucchini seeds in large plastic flats, water cactus plants, transplant tomatoes, wrap roses, and even clean soybean seeds.
The company has standardized on SolidWorks software for all new product design.
"Our designs have evolved from soap stone sketches on a concrete garage floor to 2D AutoCAD sketches and now 3D models," said Larry Flatt, executive vice president at Bouldin and Lawson.
"That evolution has opened new doors to design creativity, streamlining routine CAD functions so we can focus on discovering new approaches to machine design".
"This is at the heart of the designs for the latest generation of the WastAway process, which converts waste products to usable energy".
On its first project using SolidWorks, Bouldin and Lawson cut design time in half, from 12 weeks to six, ensuring the company could introduce a new watering system and a new trimming machine in time for the industry's largest trade show.
This reduction in design time has also given engineers more time to explore more design options for both its horticulture machines and the WastAway process.
While the horticulture machines can be as long as 25 feet, the WastAway process is massive, involving a series of machines requiring a building 265 feet long and 100 feet wide.
It has multiple shredders that break down incoming waste and also includes Bouldin and Lawson's patented steam chamber, which is the only component of its nature to continuously sterilize the processed waste.
The steam chamber makes the transformation much faster, more economical, and more environmentally friendly than other waste conversion technologies.
Design confidence.
SolidWorks enables engineers to reduce prototyping costs by enabling them to ensure moving parts such as two 20-inch blades running at 1,000 RPMs don't collide.
They can also make sure motors fit correctly within machines and still have the space to run efficiently and cool properly.
"SolidWorks gives our designers a sense of satisfaction when they can build a model and know that it works and is production-ready," said Flatt.
"It gives them the courage to try things they wouldn't have dared in 2D".
Engineers depend on SolidWorks' sheet metal capabilities to design each enclosure, mount, and assembly to exact specifications.
This precision is especially important for the WastAway system, which must efficiently process thousands of pounds of waste per day.
The next generation of WastAway - slated to be in production in a year - will convert fluff into biofuel and/or electricity.
"The green movement is fast becoming a mandate that requires solutions sooner rather than later, and Bouldin and Lawson is taking the lead in engineering waste-to-fuel technologies that are efficient and have less impact on the environment," said Rainer Gawlick, SolidWorks vice president of worldwide marketing.
"Innovating early in the design process is a huge advantage, and one that Bouldin and Lawson is capitalizing on - perhaps to set a standard for how we'll manage waste in the future".
Bouldin and Lawson works with authorized SolidWorks' reseller MK Technologies Corporation for ongoing software training, implementation, and support.
