How to Choose Which to Attend

A practical decision framework:

For brand-side sustainability and packaging teams: SPC Engage or SPC Impact. The depth of brand-side networking and the regulatory/strategic content fit the role best.

For restaurant or foodservice operators: National Restaurant Association Show plus BioCycle CONNECT for the industry-specific perspective.

For compostable product manufacturers: SPC plus BioCycle CONNECT plus selected ICC events for downstream relationships.

For industrial composting professionals: ISWA plus Industrial Composters Council. Both provide infrastructure-focused content not available elsewhere.

For policy professionals: ISWA for international perspective plus relevant US-focused policy conferences (varies by jurisdiction).

For brand strategy and marketing: Sustainable Brands plus selected industry-specific events.

For most professionals, attending 1-3 conferences per year is realistic. The selection should match role specifically; cross-domain conferences add networking but generally less direct operational value than role-specific events.

What to Do Before, During, and After

Before the conference:

• Review the agenda and identify must-attend sessions
• Identify specific suppliers, brands, or contacts you want to meet
• Prepare 2-3 specific questions or research objectives
• Schedule meetings in advance with key contacts (most conferences offer scheduling tools)
• Bring business cards (still useful at industry conferences)

During the conference:

• Attend sessions strategically; don’t try to attend everything
• Take detailed notes for specific products, suppliers, and contacts
• Ask follow-up questions in informal settings (lunches, breaks, reception)
• Collect contact information from key contacts
• Photograph interesting product samples and supplier materials

After the conference:

• Review notes within a week of return
• Follow up with key contacts within 2 weeks
• Share relevant findings with team members
• Document specific action items for the next quarter
• Subscribe to ongoing communications from suppliers/orgs of interest

The conference value compounds with proper follow-up. Many professionals attend without active follow-through and capture only a fraction of available value.

Beyond the Major Conferences

Several smaller events worth considering:

Local sustainability events. State or regional sustainability associations often run smaller conferences. Lower cost, more accessible, but narrower audience.

Vendor-hosted events. Major suppliers (World Centric, Eco-Products, Vegware) sometimes host customer events with industry experts. Low or no cost; vendor-aligned content.

Trade publications’ webinar series. Packaging Strategies, BioCycle, Resource Recycling all run webinar series that supplement conference attendance.

Online courses and certifications. Sustainable Packaging Coalition and several universities offer professional certifications for sustainability professionals.

Industry-specific workshops. Smaller events focused on specific topics (lifecycle assessment, regulatory compliance, supplier evaluation).

For professionals on tight conference budgets, the smaller events plus webinar series can substitute for major conference attendance. For those with budget for both, the larger conferences provide concentrated value while smaller events provide ongoing professional development.

ROI Considerations

A reality check on conference investment:

Time cost. A major conference is typically 2-4 days plus travel. For senior professionals, opportunity cost is substantial.

Direct costs. Registration ($1,000-3,500) plus travel ($500-2,000 depending on location) plus lodging ($500-1,500). Total typical conference attendance: $2,000-7,000.

Value generation:

• Supplier relationships: meaningful for operators, sales teams
• Industry intelligence: meaningful for strategists
• Regulatory updates: meaningful for compliance and policy professionals
• Networking: variable depending on use of relationships

Annualized value: A single relationship that develops into a supplier partnership can pay back the conference investment 10-100x. Most attendees don’t capture this value because they don’t follow up effectively. For those who do, conferences are highly leveraged investments.

For most professionals, attending 1-2 major conferences per year is good investment. Attending more without strategic follow-up generally produces diminishing returns.

Tips for First-Time Attendees

For professionals attending an industry conference for the first time:

Don’t try to attend everything. Major conferences run 6-12 simultaneous sessions across 3-4 days. Attempting full coverage leaves you exhausted and shallow. Pick the 5-8 most relevant sessions and treat the rest as optional.

Eat lunch with strangers. The cafeteria-style lunches at major conferences are when networking actually happens. Sitting at a table with people you don’t know surfaces relevant contacts faster than session attendance.

Treat the expo floor as research. Walk through the supplier expo with a specific shopping list. Compare 3-5 suppliers in your priority category side-by-side; note specific differences in performance specs and pricing approach.

Ask the same question to multiple sources. Asking “what’s the biggest issue in your part of the industry right now?” to ten different attendees produces a richer picture than any single keynote.

Carry a notebook (paper). Phone-based notes get lost in the conference deluge. Paper notes you write deliberately stay top-of-mind for follow-up.

Bring small printouts of your business or product. Even when you have business cards, having a one-page reference document (your operation’s specs, your supplier needs, your area of focus) helps the people you meet remember the conversation specifically.

Sleep at the conference hotel. The 30 minutes saved on commute compounds across 4 days. Several casual but substantive conversations happen in lobby and bar areas during evenings — being present matters.

Plan a decompression day after returning. The conference produces information overload. Take a day on return for note review, contact organization, and follow-up planning before diving back into normal work.

For first-timers, returning home with 5-10 specific contacts to follow up with, 2-3 specific products or suppliers to evaluate, and a small list of regulatory or industry updates is a strong outcome. Quality of follow-up matters more than quantity of conference activity.

What This All Adds Up To

Industry conferences in the compostable and sustainable packaging space provide concentrated value for professionals working in the segment. The seven conferences above represent the major options for different roles and objectives. Each has specific audience, format, and value proposition.

For most professionals, the right approach is:

1. Identify your role and specific objectives for industry attendance
2. Match objectives to specific conferences
3. Attend 1-3 conferences per year strategically
4. Invest in pre-conference preparation and post-conference follow-up
5. Build a small portfolio of relationships and information sources to maintain over time

The compostable industry is moving fast. Material innovations, regulatory developments, and industry consolidation all happen quickly. Conferences are one of the few venues where multiple sources converge — academic research, regulatory updates, supplier innovations, brand-side perspectives — making them efficient ways to stay current.

For new professionals in the space, attending one major conference (SPC Engage or SPC Impact) builds foundational understanding. For experienced professionals, ongoing attendance maintains industry currency and relationships.

The specific conferences listed above represent options at the time of writing. The conference landscape evolves; new events emerge and existing ones change focus. Periodically reviewing the available options and adjusting attendance choices is part of the ongoing professional development process.

Beyond conferences specifically, the broader pattern of professional development in this industry includes ongoing reading (BioCycle, Packaging Strategies, Resource Recycling publications), online networking (LinkedIn, industry-specific groups), supplier-direct relationships, and regulatory monitoring. Conferences are a piece of a larger professional development program rather than a standalone investment.

For operators, the conference investment makes most sense in the context of operational decisions — picking suppliers, evaluating new materials, understanding regulatory pipeline. The time at conferences feeds back into specific decisions made over the following 12 months. The right conferences accelerate those decisions; the wrong conferences add cost without proportional value.

Picking well requires understanding your role, objectives, and the specific conference offerings. The seven options above are the starting point; specific conference choice within or beyond this list is the role-specific work.

Background on the underlying standards: ASTM D6400 defines the U.S. industrial-compost performance bar, EN 13432 harmonises the EU equivalent, and the FTC Green Guides govern how “compostable” can be marketed on packaging in the United States.
