Understanding Product End Life in Floriculture
In the floriculture sector, understanding product end life is key. It refers to the stage where a product, such as cut flowers, specialty cut flowers, or flower buds, is no longer useful and requires disposal or repurposing. Effectively managing this phase is vital for sustainability in the ever-changing floriculture sector. In this context, sustainable practices aim to provide easy access to compostability so that floral products can be returned to the earth for regeneration to take place.
Floriculture growers who have adopted at least one sustainable practice in their operation may be more receptive to adopting additional sustainable practices and pursuing certification (Hall et al., 2010).
Industry players, including growers, should prioritize their products’ end life. A focus on compostable packaging materials and methods can greatly lessen the floral industry’s environmental footprint. This approach not only benefits the environment but also enhances the quality and sustainability of the flowers that continue to grace our homes and events.
Different Phases of the Product's Life Cycle
The life cycle of cut flowers is a journey marked by four main stages, as flowers continue through:
- Pre-production
- Production
- Post-harvest handling
- Consumer stage
With each phase bearing its own sustainability considerations, the environmental impact of the floral industry on human health can be significantly influenced.
Pre-Production Phase The journey begins with the pre-production phase, where the groundwork for cultivation is laid. This stage involves various cultivation processes that growers must manage, including soil preparation, seed selection, and planting. This critical period sets the tone for the whole life cycle, highlighting the need for sustainable practices from the outset.
Production Phase Next comes the production phase, encompassing all activities related to the growth and maintenance of floriculture products until they are ready for harvest. During this period, growers must balance the demands of quality and sustainability, often making trade-offs between resource use and flower quality. As the stage where most of a flower’s environmental footprint is generated, the production phase is a crucial element in the life cycle assessment.
Post-Harvest Handling Once the flowers are harvested, they enter the post-harvest handling phase. Here, flowers are processed, sorted, and prepared for transportation and sale. This stage requires meticulous attention to detail to maintain the quality of the flowers while minimizing waste and energy use. Proper post-harvest handling can significantly reduce the environmental impact and ensure that the flowers reach customers in the best possible condition.
Consumer Stage The consumer stage is the last stage, involving the use and end-of-life management of cut flowers. This stage includes how consumers use and dispose of the flowers. At this stage, sustainability practices center around the disposal of flowers post-lifespan and potential recycling or composting.
Consumers in the United States have shown a preference for sustainable attributes in floral purchases, such as locally sourced flowers and recycling flower waste through composting (Etheredge, 2024). This preference aligns with the higher levels of pesticide applications used in cut flower production compared to other crops, with much of the floriculture industry production occurring in developing countries with potentially fewer environmental regulations than in the United States (Etheredge & Waliczek, 2022). So, by keeping a local chain of supply, greater levels of sustainability can be achieved.
Educating consumers on proper disposal methods can help extend the life cycle benefits and reduce waste.
Environmental Footprint of Cut Flowers
The product environmental footprint of cut flowers is a significant concern, encompassing various factors such as carbon emissions, energy consumption, and water usage. The complex logistics involved in the journey of flowers from field to vase contribute significantly to their overall environmental impact.
Imported cut flowers often travel thousands of miles in refrigerated airplane holds, resulting in substantial carbon emissions. For instance, flowers flown from Colombia to US airports for Valentine’s Day in 2018 produced about 360,000 metric tons of CO2. This highlights the significant environmental cost associated with long-distance transportation of flowers both by air and by sea.
Domestic flower production, especially in cooler climates, also poses environmental challenges. The need for heated greenhouses to grow flowers like sweet pea year-round generates high CO2 emissions, further adding to the environmental footprint. Cold-chain shipping, which ensures flowers stay fresh from harvest to delivery, significantly increases energy consumption.
Water usage in the cultivation of cut flowers, particularly in high-altitude greenhouses, can lead to chemical runoff and water waste, contributing to the industry's environmental footprint (Verdonk, 2023). High-altitude, industrial-scale greenhouses consume large amounts of water, often leading to chemical runoff and water waste. As the global flower trade strives to get a bloom from field to vase in three to five days, the industry’s environmental footprint continues to grow. With many flowers being cultivated, understanding the calculation rules for water consumption can help mitigate these issues.
Challenges with Bioplastics in Floriculture
While bioplastics such as PLA (polylactic acid) present a hopeful alternative to traditional plastics in floriculture, they also bring their own unique challenges (Sustainable Plastics Review, 2022). One of the primary issues is the higher production costs compared to traditional plastics, making them less economically viable for many growers.
The challenges associated with the production and adoption of bioplastics in the floral industry include:
- Longer production time
- Limited availability of processing facilities
- Supply chain challenges, such as availability of materials and processing capabilities, varying across different regions.
Environmentally, bioplastics are not without their drawbacks. Although they are derived from renewable resources, the environmental benefits of PLA are debated. For instance, the agricultural impact of gathering raw materials for PLA, including the overuse of fertilizers and potential habitat destruction, may result in negative effects on the environment. Additionally, not all bioplastics are industrially compostable, and those that do break down into inert material with no beneficial microbes or microorganisms.
Some of the drawbacks of bioplastics include:
- The agricultural impact of gathering raw materials, including overuse of fertilizers and potential habitat destruction
- Not all bioplastics are industrially compostable
- Bioplastics that are compostable break down into inert material with no beneficial microbes or microorganisms
The challenges of recycling bioplastics in the floriculture sector include:
- The underdeveloped infrastructure for recycling bioplastics in many areas
- The lower melting point of PLA compared to other plastics, which makes it difficult to recycle together with them
- The less economically viable recycling methods for bioplastics
At the end of its life cycle, PLA can be composted, however this compost is specialized and needs to be done in a controlled commercial environment. That requires an additional investment to the process. The compost also adds no nutritional value to the soil, as once it is processed, it becomes inert and the beneficial organic properties of its natural components are lost. (Studio, Design Gang. “What Are the Disadvantages of Pla?” Gianeco, www.gianeco.com/en/faq-detail/1/6/what-are-the-disadvantages-of-pla. Accessed 24 July 2024).
Recent advancements in bioplastics have led to increased attention towards polylactic acid (PLA) due to its technological advances in productivity and functionality (Escobar et al., 2018).
These challenges underscore the need for a comprehensive approach to integrating bioplastics into the floriculture sector.
Circular Economy Model in Floriculture
By focusing on waste and pollution elimination, product and material circulation, and nature regeneration, the Circular Economy model brought forth by the Ellen MacCarther Foundation provides a transformative approach to sustainability in floriculture. This model addresses global challenges such as climate change, biodiversity loss, and pollution, making it a key concept in improving sustainability within the floral industry.
One of the principles of the circular economy is to eliminate waste and pollution, which can significantly reduce threats to biodiversity (Ellen Macarthur Foundation, 2024). By circulating products and materials, the need for production from virgin materials is minimized, leaving more space for conservation of wilderness areas. This principle is particularly relevant in floriculture, where waste from pesticide containers can be repurposed to create plastic wood and cement.
Since 2013, the circular economy initiative in floriculture has expanded to include the management of various types of residues through alliances like Retorna, Lúmina, and Campo Limpio. These initiatives aim to strengthen the implementation of the circular economy among flower-growing companies by effectively managing packaging waste.
The circular economy model not only helps tackle biodiversity loss but also promotes economic activity that actively rebuilds ecosystems. By embracing this framework, the floriculture sector can contribute to a more sustainable future while maintaining its vibrant growth.
Regenerative Agriculture Practices
In floriculture, regenerative agriculture practices play a vital role in enhancing soil health, biodiversity, and ecosystem functionality. These practices aim to restore and enhance the natural environment, providing a sustainable foundation for growing plants and flowers.
Minimizing tillage is a fundamental regenerative practice that helps soils retain carbon and improve overall soil health. By reducing soil disturbance, growers can prevent erosion, enhance soil structure, and promote beneficial microbial activity. Cover cropping is another effective method, improving soil fertility, preventing erosion, and aiding in weed management.
Interplanting different crops, including native species, can maximize space use and support soil health by varying root structures and harvest times. This practice not only reduces soil erosion but also supports local ecosystems by providing diverse habitats for beneficial insects and other wildlife. Additionally, allowing livestock to graze can provide natural fertilization and pest control while minimizing soil disturbance.
Locally grown flowers, especially those native to the area, are typically more sustainable as they require fewer inputs and support biodiversity. By adopting regenerative agriculture practices, the floriculture sector can contribute to healthier soils, more resilient ecosystems, and a more sustainable future.
Composting and Disposal Methods
Composting serves as an essential, environmentally friendly method for floral waste disposal. There are two main types of composting: aerobic (hot) composting and anaerobic (cold) composting. Both methods can contribute to soil fertility and reduce waste sent to landfills, making them essential practices in sustainable floriculture.
Aerobic composting requires a holding receptacle that allows for breathing, which can be made from materials like pallets or chicken wire. A proper compost pile should have a balance of carbon materials (like dry leaves and dead garden debris) and nitrogen materials (such as fresh cut grass and coffee grounds) in a ratio of 1:1. Turning the compost pile with a pitchfork every three to four weeks ensures proper aeration and accelerates decomposition.
Anaerobic composting, on the other hand, involves breaking down organic matter without oxygen. This method is slower but can be useful for composting in areas with limited space or where turning the pile is not feasible. Both methods require proper moisture, temperature, and oxygen levels to enhance the decomposition process and produce nutrient-rich compost.
Incorporating composting practices not only aids in waste management but also enhances soil health, providing nutrient-rich compost that can improve the sustainability of the floral industry (Chadar et al., 2018).
By incorporating composting practices, growers can improve soil health and contribute to a more sustainable floral industry.
Case Studies: Sustainable Floriculture Initiatives
Sustainable floriculture initiatives demonstrate the industry’s ability to adopt eco-friendly practices without compromising high-quality flower production. These initiatives often focus on composting, using reusable or recyclable materials, and ensuring fair wages and healthy working conditions for workers.
One such initiative involves composting botanical scraps and using reusable, recyclable, or compostable vases and containers. These practices help reduce waste and promote a circular economy within the floral industry. Additionally, sustainable florists educate suppliers, colleagues, and consumers about ways to promote sustainability in the flower trade.
Fair wages and healthy working conditions are also essential elements of sustainable floriculture. Third-party certifiers like Veriflora, BloomCheck, Fair Trade, and Rainforest Alliance ensure that flowers meet sustainability standards and that workers are treated ethically. These certifications provide transparency and assurance to consumers that their floral purchases support sustainable and fair practices.
By adopting sustainable practices and obtaining third-party certifications, floriculture businesses can achieve greater sustainability and contribute to the well-being of the environment and the people involved in the flower trade.
