"Receiving the Harvey W. Gershman Undergraduate Scholarship is truly an honor and a reminder that the work I have been doing to bring more visibility to solid waste management matters. As a student from Puerto Rico, I see firsthand how important this field is for islands with limited land and resources.

GBB Reading: Published Articles

As thought leaders, GBB consultants regularly contribute articles to leading industry publications, sharing insight and information on important topics. Recently published articles include:

Evaluating Commercial Composting Technologies


Steven Schilling, P.E., GBB Vice President


Waste Today – September 2026


With a need for increased organic waste diversion, commercial facilities and municipalities are re-evaluating how processing technology affects efficiency, odor control, and long-term costs. Choosing between turned windrow, aerated static pile (ASP), and covered aerated static pile (CASP) systems requires balancing capital expenditure, throughput speed, and available footprint.


In Waste Today, GBB Vice President Steven Schilling evaluates the operational trade-offs, technical advantages, and economic factors of each technology to help operators build a smarter composting strategy.

How Organic Waste Container Design Improves Collection Programs


Chris Lund, P.E.

GBB Executive Vice President


Waste Today – July 2026


Across the country, as organics programs expand, cities and haulers are rethinking how container design can make food‑scrap collection cleaner, easier, and more efficient. Features like tighter‑sealing lids, reinforced carts, and clearer labeling are helping reduce contamination and improve participation.


In Waste Today, Chris Lund explains how smart container choices strengthen organics programs and support long‑term system performance.

Factors to Consider When Expanding a Transfer Station


Chris Lund, P.E.

GBB Executive Vice President


Don Birnesser, P.E.

GBB Principal Engineer Associate


Waste Today – July 2026


As transfer stations evolve into central hubs for modern materials management systems, public agencies and private operators are expanding their capacity to manage higher throughput, longer haul distances, and a growing mix of material streams.


In Waste Today, Chris Lund and Don Birnesser discuss how thoughtful planning for transfer station expansions can lower long-term costs, support diversion goals, and improve system resilience.
