Making Green Bay, Wisconsin a little greener every day.


Greener Bay Compost is the ONLY Curbside Compost Pickup Service in the Green Bay, Wisconsin metropolitan area. Founded in July 2021 by Cory Groshek, we currently serve residential customers in all of Green Bay, plus Allouez, Ashwaubenon, Bellevue, De Pere, Hobart, Howard, Ledgeview, and Suamico.

Our service, which is essentially a Waste Management service mixed with a Recycling operation, is modeled after similar services in other parts of the country, the intention of which is to reduce organic waste by diverting it from landfill and into our compost piles, where it will be upcycled into a product infinitely more useful and valuable.

Per the Wisconsin DNR’s (Department of Natural Resources) 2020-2021 statewide waste characterization study, approximately half of what ends up in our landfills is (or could have been, at some point) compostable, and we are not okay with that, especially whereas much of this material still has massive nutritional and vitamin value.

Accordingly, we have come into existence to tackle this problem head-on, by removing material from the waste stream and giving it a second life, as something that will help create new life in our local communities!


Every other week, we take our subscribers would-be organic waste (such as fruit and vegetable scraps, spent coffee grounds, egg shells, and plain paper/cardboard items), which would normally end up in a landfill, and turn it into a nutrient-dense soil amendment called “compost,” which we then sell for use in local gardens, flower beds, agricultural operations, etc.

The composting process we use is a process known as “hot composting,” which involves building piles, which are at least three feet wide by three feet long by three feet tall, using a wide variety of organic materials. The piles are well-mixed/layered to ensure a proper ratio of high-nitrogen materials (such as most food scraps, garden waste, spent coffee grounds, etc.) and high-carbon materials (such as shredded plain paper and cardboard, fall leaves, wood shavings, etc.), turned/aerated approximately once per week, and moistened, as necessary, to promote the proliferation of the tiny microbes that live inside the piles.

These tiny microbes are responsible for the breakdown of the materials that enter our compost piles into what will eventually become “finished compost.” As new materials are added to our piles, the microbes consume them, which results in the core of our piles rising in temperature to somewhere between 130 and 160 degrees for a week or two at a time. This is why, when we turn/aerate our piles, it is not uncommon to see plumes of steam rising from them; a very cool visual, if ever there was one, and a sure sign our process is working!

After approximately two months or so, the materials that entered our compost piles no longer resemble their original selves and appear instead as a dark brown, homogeneous material, which very closely resembles soil. At that point, we leave this material to sit for about another month or so, in what is known as the curing phase, to allow it to cool off and mature to the point where it is ready to use.


To collect the material for our compost piles from our subscribers, we use Food Safe, five gallon buckets, each of which comes with a lid on top, a BPI-certified compostable liner inside, and approximately half a pound of sawdust/wood shavings in the bottom to help absorb moisture and control odor.

After dropping off each subscribers initial bucket, we return to each subscribers household every other week to swap out their full buckets for clean, new ones.


As of the time of this writing, we have over 120 residential subscribers in the Green Bay metropolitan area, have diverted well over 18,000 pounds (nine tons) of our subscribers waste from landfill, have produced thousands of pounds of compost, and have been featured on/in the news three times (including on NBC26, Fox11, and Local 5 Live), and we are growing every day.

We are currently looking into the feasibility of providing a Compost Pickup Service for Businesses, On-Demand Pickup Services for large amounts of one-time organic waste (such as fall leaves, confidential paper documents, cardboard, etc.), and a Compost Drop-Off Service for individuals and groups whose living situations do not lend themselves well to our cornerstone Curbside Compost Pickup Service. We also plan to, at some point, expand our Curbside Compost Pickup Service into the Fox Valley area, which includes Appleton, Combined Locks, Grand Chute, Kaukauna, Kimberly, Little Chute, Menasha, and possibly Neenah. For now, however, we remain focused on providing the best and most sustainable service possible to our existing, Green Bay area subscribers.
