Environmental Practices
McGinnis Institute of Beet Sugar Technology 2014Mr. Louis Knieper
Purpose
• Gain familiarity with the environmental issues that affect beet-sugar manufacture
• Understanding of why these rules exist• Gain familiarity of how beet-sugar
manufactures are complying with the rules• Understand that compliance is not optional
Topics
• General discussion on the environment• Environmental Rules• Air issues for beet-sugar manufactures• Water issues for beet-sugar manufactures• Solid-waste issues for beet-sugar
manufacturers• Enforcement of the rules
What is the Environment?
What is Pollution?
Who is a Polluter?
Who Protects the Environmental?
What does Toxic Mean?
How Much Should Companies Spend on Environmental Protection?
Minn-Dak Environmental Spending
From: Jeff L. Carlson, VP OperationsSent: Tuesday, March 15, 2005 3:11 PMTo:Steve M. Caspers, CFOCc: David H. Roche, CEOSubject: Environmental Expenses 1997-2005 Total Capital Projects $29.7 millionEnvironmental Projects 5.59 million (18.8% of total capital projects) FY 2004 Environmental Expenses$2,750,000 (this includes all mud, limestone, rock and trash, air pollution control,
wastewater processing, permitting and other expenses)
“But there are limits to how responsibly companies can behave when behaving responsibly raises their costs and consumers are unwilling to pay higher prices. The most important constraint on the pursuit of virtue is the market”
David Vogel, Professor. Haas School of Business, University of California, Berkeley and author of The Market for Virtue: The Potential and Limits of Corporate Social Responsibility
Beet Sugar Manufacturing and the Environment
Inputs for Beet Sugar Manufacture
• Sugarbeets• Fuel
• Coal• Natural Gas • Petroleum• Coke• Biofuels
• Air• Electricity
Inputs for Beet Sugar Manufacture
• Limestone• Processing Chemicals• Sulfur or SO2
• Cleaning Chemicals• Filtering Materials• Maintenance Chemicals• Maintenance Items (parts,
metal, wood,etc.,)
Inputs for Beet Sugar Manufacture
• Capital Assets• Buildings• Land• Equipment

Products and Byproducts
• Sugar• Pulp (wet or dry)• Molasses• Separator Concentrate
Every Step of Beet Sugar Manufacturing Generates Wastes
• Piling and Storage• Washing• Diffusion• Pulp Drying• Juice Purification and
Evaporation• Crystallization• Steam Production• Wastewater Treatment• Solid Waste Handling• Sugar Packaging• Sugar Shipping
Wastes from Piling and Storage of Sugarbeets
• dirt and rocks• weeds• beets and beet parts
Wastes from Beet Cleaning
• dirt and stones• weeds• beets and beet pieces• wastewater
Wastes from Diffusion and Purification, Evaporation and Crystallization
• Wastelime• Unburned rock from
limekiln• Combustion gasses from
limekiln• Noncondensable gasses• Spent chemical cleaning
solutions• Spent softener
regenerating solutions• Condensate
Wastes from Pulp Handling and Drying
• Discarded pulp• Combustion gasses• Water vapor• Condensed water• Ash• Dust from dust collectors
Waste from Steam and Power Generation
• Ash• Combustion Gasses• Pollution control wastes
(water, dust, chemicals, filters)
Wastes from Wastewater Treatment
• Sludge (biosolids)• Nutrients• Noxious gasses
Other Wastes• Used oil• Discarded parts and
equipment• Construction Wastes• Maintenance Wastes• Trash and Garbage• Discarded Beets• Contaminated Storm
water • Contaminated Soil

Strategies for Handling Environmental Compliance
• Prevention• Treatment for Reuse
or Release• Release to the
Environment• Storage
Prevention (avoids the problem of pollutants)
• Goes hand-in hand with cost reduction• Fuel efficiency• Lower Wastewater
Generation• Can take large capital
investment• Steam pulp dryer• Dry beet handling
Treatment for Reuse or Release (Removes or reduces pollutants to acceptable levels)
• Treatment for Reuse• wastewater• waste lime
• Treatment for Release• Stack Gasses• wastewater
• Treatment systems often generate their own wastes• dust (particle removal)• sludge (wastewater
treatment)
Release into Environment
• Limited Capacity to accept Pollutants
• Highly Regulated• Carefully Monitored
Almost all Discharges Are Regulated
• EPA• State Department of
Health • Tribal Environmental
Council• County Board• City Council
Penalties for not Obeying Environmental Rules
• Civil and Criminal • Fines• Jail• Disqualification• Escalating
Discharging to the Environment is Costly
• Large Amount of Material• Compliance Costs
• Permitting• Pre-discharge costs• Discharge monitoring• Post-discharge costs
• Fines if there are problems
Temporary and Permanent Storage (Staging Areas, Landfills and Ponds)
• Ownership and Operations
• Permitting• Ongoing Care• Liability
Strategy for Environmental Protection must Balance many Issues
• Balance Costs and Benefits
• Should fit into larger corporate strategy
• Should consider outside stakeholders
• Should consider short- and long-term consequences
Environmental Stewardship is the Right Thing
• Protects Nature• Good Neighbor• Reduces Expenses
(can make money)• Prevents Trouble• Part of the Job
