What You'll Learn
Land O' Lakes' recycling programs
Land O' Lakes has been working on a closed-loop packaging system since 2018, when it partnered with Northstar Recycling in Longmeadow, Massachusetts, to recycle woven polypropylene (PP) feed bags. The company has been collecting and recycling its Purina cattle feed tubs, which are made from high-density polyethylene (HDPE). This is a tough and logistically complex task that has involved forging partnerships with dealers, a lumber manufacturer, and a Massachusetts-based recycler.
The process involves collecting the empty feed tubs, shredding and pelletizing them, and then turning them into lumber products such as park benches, fence posts, and floating chicken coops. This closed-loop system is an innovative and sustainable way to manage feed tubs while also creating a safe space for chickens during floods.
Land O' Lakes is now expanding its tub and bag collection and recycling programs in the Southwest, Midwest, and Northeast, with the primary products being benches and fence posts. The company is also looking to find more uses for the recycled materials, such as incorporating them into horse stalls and other agricultural products.
While the specific recycling programs and capabilities may vary by location, there are some general guidelines for recycling plastic tubs. Plastic tubs are typically made from materials like polypropylene (PP) or high-density polyethylene (HDPE) and can often be recycled through curbside recycling bins. However, black-colored tubs, tubs made of PP plastic, and oversized bulky tubs may require specialized recycling. It is always recommended to check with local recycling centers or authorities for the most accurate and up-to-date information.
Additionally, some alternative methods for recycling plastic tubs include donating them to thrift shops, giving them away on websites like FreeCycle, or recycling them through community hubs like Walmart.

Plastic lumber products
Land O' Lakes is working on a closed-loop packaging system, collecting and recycling its Purina cattle feed tubs, which are made from high-density polyethylene (HDPE). These tubs are being recycled into unique lumber products, such as park benches, fence posts, and floating chicken coops.
Plastic lumber is an eco-friendly alternative to wood, made from recycled plastics. It is long-lasting, maintenance-free, and can be cut and shaped with standard woodworking tools. Plastic lumber does not need to be treated or painted and is resistant to graffiti, splintering, cracking, chipping, moisture absorption, and rot. It is also unaffected by termites, rodents, worms, and other pests. Additionally, it does not leech toxins or carcinogens into the soil.
Plastic lumber is available in various grades, including moulded, structural, and premium, making it suitable for a range of construction projects. It is often used for decking, but can also be used for furniture, playground equipment, and even swim platforms. The lumber is typically sold with the same dimensions as wood lumber, as these sizes have become industry-standard.
Plastic lumber is a sustainable option, reducing the amount of plastic waste that ends up in the environment. By using recycled plastic bottles, detergent containers, and milk jugs, plastic lumber manufacturers contribute to the circular economy and provide a durable and aesthetically pleasing product.

Recycling plastic tubs
Plastic tubs are often made from materials like polypropylene (PP) #5 or high-density polyethylene (HDPE) #2, which are technically recyclable. However, recycling guidelines vary based on location, so it's important to check with your local recycling center or municipal authority for specific instructions. Some facilities may have specialized recycling requirements for black-colored tubs, tubs made of PP #5 plastic, and oversized tubs.
To recycle plastic tubs, start by checking if your local curbside recycling program accepts them. If not, look for drop-off locations or specialized recycling programs in your area. Before placing tubs in the recycling bin, ensure they are clean and dry, as residue can be a challenge for recyclers. You can also melt down HDPE tubs to create plastic lumber products, such as benches, fence posts, and floating chicken coops, which are more tolerant of contamination.
Some companies, like Land O' Lakes, have initiated closed-loop recycling programs for their Purina cattle feed tubs, partnering with recyclers to collect, shred, and pelletize the tubs for secondary product manufacturing. These programs aim to create sustainable solutions for their packaging and benefit the community, such as providing chickens with a safe retreat during floods.
If you have many plastic tubs to dispose of, consider donating them to thrift shops or giving them away on websites like FreeCycle. Additionally, some retailers, such as Walmart, offer community recycling hubs where you can recycle various materials, including plastic tubs. Remember that recycling practices can vary by region, so always check with your local guidelines to ensure proper disposal.
Lastly, it's worth noting that not all plastic tubs are designed to be recycled, and sometimes, it may be cheaper for manufacturers to use raw, virgin plastic. As a result, a significant amount of plastic packaging ends up in landfills, incinerators, or oceans. To combat this, some MRF operators are working with manufacturers to design more recyclable packaging, and consumers can play a role by increasing their recycling efforts, especially with highly desirable recyclables like plastic bottles.

Local recycling variations
The recyclability of plastic tubs, including those from Land O'Lakes, can vary across different localities. While some areas may accept plastic tubs for recycling, others may not due to various factors.
One factor is the type of plastic the tub is made from. Plastic tubs are often made from polypropylene (PP) or high-density polyethylene (HDPE), both of which are technically recyclable. However, the presence of additives or layering with other polymers in HDPE can complicate the recycling process. Additionally, small plastic items can cause issues for recycling equipment, and some facilities may not accept them.
The availability of specialized recycling programs in an area can also influence the recyclability of plastic tubs. For instance, black-colored tubs, tubs made of PP plastic, and oversized tubs may require specialized recycling and may not be accepted through standard curbside recycling programs.
The acceptance of plastic tubs for recycling can also depend on the capabilities and preferences of local recycling facilities. Some facilities may only accept certain shapes, such as bottles, jars, buckets, or round containers, while others may have specific requirements for preparing and cleaning the tubs before recycling. It's important to check with local recycling centers or municipal authorities for accurate and up-to-date information.
In some cases, local partnerships and initiatives can impact the recyclability of plastic tubs. For example, Land O'Lakes has partnered with recyclers and manufacturers to collect and recycle their Purina cattle feed tubs, converting them into lumber products like park benches and floating chicken coops. Such initiatives can vary across regions and may influence the recyclability of specific products.
It's worth noting that recycling guidelines can vary significantly from one locality to another. While some areas may have robust recycling programs that accept a wide range of materials, others may have more limited options. Checking with local authorities or using online recycling locators can help individuals determine the specific recycling variations in their area.

Plastic recycling challenges
Plastic recycling is a complex process that requires collaboration between manufacturers, suppliers, and other stakeholders to overcome various challenges. One significant challenge is the fact that plastic is not a single material but encompasses several hundred different kinds of materials with unique properties. This diversity in plastic types makes it challenging to recycle them effectively, as different plastics have different melting points and are not always compatible with each other. For instance, thermosetting polymers like unsaturated polyester or epoxy resin cannot be mechanically recycled due to their permanent cross-linking in the manufacturing process.
Another challenge arises from the combination of different plastic types and other materials, such as glue and metal, during the manufacturing of products. This makes it difficult to separate and recycle the plastic content, requiring specific expertise and knowledge of materials. Additionally, small plastic items, roughly 3 inches or smaller, can cause operational issues for recycling equipment, often getting caught or falling between the belts and gears, leading to them being treated as trash.
The recycling process itself presents challenges, such as the need for proper separation and disposal methods. While recycling is environmentally and economically beneficial, it is vulnerable to market fluctuations, with virgin raw materials sometimes being cheaper than recycled plastic. This can result in packagers opting for raw, virgin plastic instead of recycled alternatives. Furthermore, the lack of standardized recycling practices contributes to the complexity, as what is recyclable in one community might be considered trash in another.
To address these challenges, it is crucial to promote collaboration and knowledge sharing throughout the product chain. By working together, manufacturers, suppliers, and stakeholders can design products with recycling in mind, making it easier to disassemble and recycle end-of-life plastic products. Additionally, implementing policies that promote the use of environmental design principles can significantly impact recycling performance, reducing plastic waste and diverting it from landfills.
