This framework seeks to create production techniques that are not just efficient but are essentially waste free. Glass is 100% recyclable, and can be recycled an infinite number of times with no loss of quality in container manufacturing. There are numerous examples of companies investing in eco-innovation strategies to generate significant cost savings, both in the middle and long term, thereby improving turnover and increasing margins. They also claimed that ‘Where Sainsbury's cannot use compostable material, it uses recyclable’ (J Sainsbury plc, 2006b). Cradle to Cradle society must all come from what is termed ”current solar income”, defined as photovoltaic, geothermal, wind, hydro and biomass. This would later become the Cradle to Cradle design framework, which is the practical approach to product 3 Although the ES concept is still in its experimental stage, it has been recently used as a starting point for elaborating plans and measures in some new development projects by VLM in Flanders. In 2007 (not shown in Fig. There are stringent tests required to demonstrate compliance with the guidelines. Thus it is divided into several steps (Figure 12). Also, paper and paperboard represents the largest proportion by weight of packaging material used. In the end, the government (G) is likely to accept the advantages of the C2C approach and will also move from a “vertical” command-and-control mode into a “horizontal” participatory mode, expressed by permitting controlled self-regulation. Figure 2 illustrates that this “wicked” problem had no simple, straightforward answer nor that only researchers possessed the required knowledge. When the materials are safe, then the consumer is safe, and perhaps more importantly, the ecosystem is safe. Mono-layer recycled bottles are used for detergents, bleach and other household chemical bottles. Figure 2. Two lines are presented in Fig. The qualities of the landscape and the services they provide were taken as a starting point for the social and economic development of the area. Cradle-to-cradle processes include biological and technical cycles: A biological cycle includes materials that can be safely returned to the soil through a degradation process. Choose a single recyclable material for all components of the package, e.g. Recycling rates for some countries are provided in Table 10.2, although the methodology used for data collection may not always be consistent between countries; they should be used as a guide only. Multiple trips in an RPC closed operating system led to material efficiencies that created relatively low environmental burdens that were only partly offset by backhaul and cleaning steps. A key component of Cradle to Cradle® design is the recognition of and design for the two nested cycles – biological and technical. Pellerano, in Encyclopedia of Toxicology (Third Edition), 2014. It is also important to consider the cost of the package in relation to the value of the product (Chiellini, 2008). Technical nutrients are manufactured products that can be reprocessed continuously through industrial systems. When production of starch (the source for the lactic acid) is optimised, the environmental advantages for corn increase. While the UK produces plenty of clear glass, much of it is exported as bottles for spirits. By comparison, a large amount of green glass, principally as wine bottles, is imported and collected for recycling. In general Exergy Analysis and LCA have been developed separately even though they are strongly linked. Table 11.1. It is difficult to compare packaging costs without also including, for example, the costs of shipping containers, depreciation costs of packaging machinery, labour requirements, etc. As can be seen from Table 7.1, the overall production in 2010 had recovered to what it was in 2007 before the 2008 economic crisis. All constituents are chemically harmless and recyclable. We use cookies to help provide and enhance our service and tailor content and ads. Pro: Environmental Concerns This is the obvious and most attractive feature of the cradle-to-cradle design system. The next sequence of workshops focused on provisioning and regulating services. An LCA study comparing egg packaging made from PS or recycled paper (Zabaniotou and Kassidi 2003) found that PS packages contributed more to acidification potential and smog, while recycled paper packages contributed more to heavy metal and carcinogenic substances impact. Embodied energy savings per kilogramme in the production of recycled product, compared to virgin product. Within a rather large area of about 20,000 ha, 13 important stakeholders, including the Province of Limburg and seven municipalities, asked for territorial development in De Wijers.” Several previous attempts to start up this process had not succeeded. These materials, therefore, present a commercial opportunity for retailers, brand owners and packaging suppliers to enhance their brand image and demonstrate corporate social and environmental responsibility. In 1998, Dutch researchers devised a mineral accounting system (MINAS) for the government (boxes 6 and 7) to satisfy the nitrate guideline in a major research effort applying K3 level knowledge (box 6). ), GAIA (Quezon City, Philippines, and Berkeley, Calif.), the Zero Waste International Alliance (ZWIA), and others. The FDA will provide a ‘letter of no objection’ to the use of a particular resin in a particular application, if the recycler is able to demonstrate that there is negligible risk of contaminants migrating from the container into the contents. List some examples from your own experience. This was achieved through the purchase of wind-power-derived renewable energy certificates (RECs), which serve as an offset to cover all of the emissions from the energy used for the production of PLA. There are many different plastics used in packaging (see Table 10.3) but the most recyclable are PET and HDPE. Of an estimated 4500 landfills operating in the United States in 1993, only 127 had gas-to-energy operations (Denison, 1996, p. 215). HDPE, high-density polyethylene. Both the level of participation and the outcome of the workshops were satisfactory. In nature, the “waste” of one system is food for another. (2001, p. xi). More emphasis should have been given to environmental monitoring providing specific data, using, for example, new automatic sensors that are available now (Bouma, 2011). Overall, the paper package had less environmental impacts than the PS. Figure 19.6. Sep 10, 2020 - Biological and technical nutrients (C2C) - Cradle-to-cradle design - Wikipedia An earlier focus on preserving wild lands and protecting endangered species has been expanded to include the need to protect all living things. Coated fibre-based packaging is expanding into new applications; for example, a coated paperboard butter tub was used by Carrefour, France for its home-brand butter in 2000 (Scandinavia Now, 2000). They are also investing heavily in biomass energy, which usually involves wood chips/wood waste. Recently Peter Brabeck-Letmathe the former CEO of Nestlé, the world’s largest food and beverage company, warned that the growing use of such crops as wheat and corn to make biofuels is putting world food supplies in peril. Environmentalists such as Lester Brown, president of the Earth Policy Institute, question the morality of turning a foodstuff into packaging when so many people in the world are hungry. By 2050, global food supply will need to increase by around 70%, which is disproportionately higher than the population growth of approximately 30% predicted by the United Nations from 7 billion people currently (FAO, 2009). Table 7.3. According to a Confederation of European Paper Industries (CEPI; www.cepi.org) survey of its membership, paper and paperboard used for packaging accounted for 43% of output in Europe during 2009. In an attempt to improve its environmental profile, NatureWorks™ announced in 2005 that it will achieve a GHG-neutral position for its PLA, making it the first, and only, commercially available GHG-neutral polymer in the industry. To this purpose, they established a farmers’ cooperative also exploring introduction of various product–market combinations leading to higher future farmer's income. Technical nutrients can be recycled or reused with no loss of quality and biological nutrients composted or consumed. (2007) reported that compared with the life cycle of gasoline and diesel, ethanol and biodiesel from corn rotations reduced global greenhouse gas (GHG) emissions by ~40% and from switch grass and hybrid poplar by ~115%. In 1994, a law was passed requiring farmers to inject liquid manure into the soil rather than spread it at the surface. The Cradle to Cradle® design concept recognizes two cycles for materials: the technical and the biological cycles. Recently, a cradle-to-polymer-factory-gate life cycle inventory data (eco-profiles) for the 2006 and the near-future PLA production systems was published (Vink et al. For every life process the total inflow and outflow of energy and material is computed, thus, LCA is similar to Exergy Analysis. ), the Zero Waste Network (Austin, Tex. Cradle to Cradle utilises renewable energy, protects the ecosystem and uses natural resources efficiently. The cradle to cradle framework requires packaging to be designed for either technical or biological cycles. The following lessons can be learned when analyzing the flow of knowledge in Fig. This was intended to reduce ammonia volatilization that, in turn, was expected to result in less deposition in adjacent nature areas. This framework seeks to create production techniques that are not just efficient but are essentially waste free. The US environmental movement is very large, diverse, and growing. It is not necessary, nor is it technically feasible, to recycle everything in the municipal waste stream. By contrast cradle-to-grave (in the authors’ view) refers to a company taking responsibility for the disposal of goods it has produced, but not necessarily putting the constituent product components back into service. Governmental agencies were strictly enforcing the rules but ultimately open to change as evidenced by the experimental permits provided in the period 2006–2012. The sustainability credentials of a product and its packaging can serve as a point of differentiation for a brand and add value for consumers through assurance of ecological and social responsibility. Corrugated boxes and glass bottles are typically recycled in a closed-loop system. A recent application is beverage bottles, for example Biota Brands (US) for their spring water (Biota, n.d.) and Naturally Iowa (2007) for its natural and organic milk. Cradle design is about creating continuous cycles of both biological and … Independent certification provided by the Carbon Trust complies with the requirements of internationally recognized standards (BSI 2008): PAS 2050: 2011; the Product Carbon Footprint Protocol parts 1 & 2; and the certification requirements of the Carbon Trust’s Footprint Expert Guide (v4.1). Research analysis was carried out internally, therefore allowing not only for supply chain analysis to be carried out with complete transparency but also for capacity building within the business; allowing for continued and more varied environmental analyses to continue as knowledge develops. The idea is perhaps stated most simply in a book called Cradle to Cradle: Remaking the Way We Make Things by William McDonough & Michael Braungart: “Imagine a world in which all the things we make, use, and consume provide nutrition for nature and industry–a world in which growth is good and human activity generates a delightful, restorative ecological footprint.”. Verghese et al. In 1992, the FDA released guidelines on the use of recycled plastic resins in food packaging which have recently been updated (FDA, 2006). These substances were selected for inclusion on the Banned Lists due to their tendency to accumulate in the biosphere and lead to irreversible negative human health effects.

Adapted from Gertsakis et al. Sainsbury's is introducing compostable plastic packaging for many of its organic products. They concluded that recycling is not always necessarily the preferable waste management solution since it is limited by the second law of thermodynamics and obeys the law of diminishing returns. Wall thickness, pigments and coatings (particularly over-printing and lacquers) can be critical factors in the rate of degradation. In other words, industry can be modelled on natural processes, and these industrial materials can be productively cycled. This new approach has generated a host of innovative ideas including biomimicry, green chemistry, clean production, and zero waste. The ISO defines compostable as ‘A characteristic of a product, packaging or associated component that allows it to biodegrade, generating a relatively homogenous and stable humus-like substance’ which does not ‘negatively affect the overall value of the compost as a soil amendment’ or release ‘substances in concentrations harmful to the environment at any point during decomposition or subsequent use’ (Standards Australia and Standards New Zealand, 2000, p. 9). A study by WRAP (Hartley and Lee 2006) concluded that bulk containerisation had the greatest potential benefit on cullet recovery in the UK, these benefits being maximised if the required wine bottles were produced in the UK. When utilized correctly, C2C ensures the smallest possible environmental footprint. It is used to manufacture containers in one of two ways: by co-extruding the container with a layer of recycled resin sandwiched between two layers of virgin resin; by moulding mono-layer bottles with up to 100% recycled resin. Researchers (K) were primarily focusing on various forms of disciplinary research. The phrase ‘cradle-to-cradle’ used by the SPC was first coined by Walter Stahel from the Product-Life Institute in Geneva in the 1970s; it was popularised in 2002 by William McDonough and Michael Braungart in their book Cradle to Cradle: Remaking the Way We Make Things. Available from Amazon . A mill needs steam-heated drying rolls plus electricity for drying paper and board. The material is compostable but it also dissolves in water (Fig. Deemed to be ecologically safe, these materials are rapidly renewable and biodegradable. The very revolutionary concept of cradle to cradle is the base for the world of sustainable design and manufacturing. A final workshop focused on social and economic opportunities. In life cycle assessment (LCA) comparisons between fossil fuel and biofuel, the method used, especially the allocation method, determines outcomes, and is widely disputed within that research community (Huppes and Ishikawa 2007). Technical nutrients can be recycled or reused with no loss of quality and biological nutrients composted or consumed. The presence of iron oxide in cullet (for example from contact with rusty metal, or from plate glass with high levels of iron for ultraviolet light protection) gives glass a distinctive green hue. This means that all products return to the cycle of manufacture, consumption and renewal at the end of their useful life. This means that the raw materials of the product, which under the cradle-to-cradle model fall into the categories of “technical nutrients” and “biological nutrients” typically have little or no toxic or adverse effects on the environment or the end user. The primary energy saved is about 13% of the energy required to make glass containers from virgin raw materials. By continuing you agree to the use of cookies. It calls for a radical change in industry: a switch from a cradle-to-grave pattern to a cradle-to-cradle pattern. First, Dutch researchers, using a K3 approach, presented a so-called derogation plan to the EU allowing farmers to temporarily apply 240 kgN ha−1 from manure rather than the required 170 kgN. The upper (K) line represents more traditional, rather monodisciplinary research that certainly made significant contributions even though some (MINAS in boxes 6 and 7) did not work out. Unless recycled or reused, their use in packaging may possibly incur a high carbon footprint, particularly when used as an energy source. But lobbying by farmers, supported by a number of politicians, changed the scene. Modern, ‘sanitary’ landfills are built to avoid or minimise surface and groundwater contamination through careful siting and use of clay and plastic liners. Cradle to Cradle ® is a registered ... multiple technical and biological nutrient components (from thread to zipper) to reach product certification at the Gold level. What if there was such a thing as fifth-class postage that existed solely for the purpose of returning packaging to the manufacturer? World production percentage of paper and paperboard by region between 2002 and 2010. Cradle to Cradle ® Design transmits the principle “Quality equal Quantity” to industrial systems. In 1997, farmers organized into a small environmental cooperative, that was later expanded (box 4). Cradle to cradle models industrial resources to biological nutrients and explains a continuous transformation this nutrient. Do not use a compostable polymer for products that are similar or identical to those that already have an existing recycling programme, because there is likely to be cross-contamination. 2008) showed that fuel production from corn leads to higher environmental impacts compared with the fossil counterpart although the result depended on the energy demand of bioethanol production. Cradle to cradle can be defined as the design and production of products of all types in such a way that at the end of their life, they can be truly recycled (upcycled), imitating nature’s cycle with everything either recycled or returned to the earth, directly or indirectly through food, as a completely safe, nontoxic, and biodegradable nutrient. A series of papers on issues relating to packaging and the environment are produced by Europen (2016). manufacturing both pulp and board) in Cumbria, UK. All rights reserved. Leachate is recovered and treated. Once a C2C plan has been established and the materials have been sourced, the product can be manufactured at the same level of speed and quality. An increasing number of companies are specifying degradable or biodegradable polymers for packaging. But strict controls will be enforced to check the control mechanisms of the farmer cooperative. The environmental cooperative organized many meetings among its farmers to share experiences (at K1 level). A later energy-based evaluation (Hocking 1994) showed that paper cups consumed less energy than PS foam cups. Fig. If the package requires more than one material, and these materials are incompatible in the same recycling process, then they should be designed for easy separation by the consumer into different recycling streams (e.g. Cradle to Cradle® shapes nutrient cycles from the very beginning so that the materials and chemicals used are favourable for the technical or biological cycle. In their 2002 book Cradle to Cradle: ... Everything can be designed to be disassembled and safely returned to the soil as biological nutrients, or re-utilized as high quality materials for new products as technical nutrients without contamination. In their view, the best way to remove all the unfair barriers to the development of recycling would be a transparent procedure to generate realistic recycling targets. Principles climatex® considers nature, where waste equals food, to be its role model. Jan Verboven, Paula Ulenaers, in Ecosystem Services, 2013. There are a variety of new technologies available to sort glass and remove contaminants automatically. Ensure that the design of the product supports degradation. In the last quarter of the twentieth century, citizens began to insist that other valid ways of knowing must be brought to bear as well – perspectives of local knowledge, spiritual values, history, ethics, EJ, fairness, and democratic participation and consent in decisions by those who are affected. Since much of the transportation takes place by truck, mobile source emissions are likely to increase. Fellows, in Food Processing Technology (Fourth Edition), 2017. This follows massive investment, most notably in China, in large and fast machines as well as new mills. In addition, they suggested a “horizontal” self-governance approach requiring clear and transparent environmental guidelines. Technical and biological nutrients Cradle-to-cradle design means literally designing waste right out of the lifecycle of the package. Putting aside the present limited availability of renewable energy, this criterion is controversial in light of recent reports that raise questions about the ecological impacts of growing crops for biofuels, particularly when rainforests are cut down to plant crops such as palm oil (MacKinnon 2007), as well as the impact on the price of staple food items such as corn, wheat and soy beans when land previously used to grow these crops for food is now used to grow crops for biofuels. 2004). This was intended to reduce ammonia volatilization that, in turn, was expected to result in less deposition in adjacent nature areas. Use of the concept of ecosystems goods and services stimulated stakeholders to think on a more regional level and in a more integrated and sustainable way about the De Wijers project area. G.L. However, it is important that benefits of innovation for sustainability are clearly communicated, such that consumers can understand and fully appreciate them (refer to Section 7.2.1 for further discussion of this topic). Recyclable packaging also needs to be designed to minimise the number of different materials and to avoid materials that could contaminate the recycling stream (see Box 10.2). If as predicted biofuels are used to satisfy 20% of the growing demand for oil products, there will (in his view) be nothing left to eat; to grant enormous subsidies for biofuel production is morally unacceptable and irresponsible. Regarding the first criterion, whether or not packaging is beneficial is a subjective judgement; today all packaging on the market has to be safe and healthy for individuals and communities throughout its life cycle and this is reflected in the regulations such as (in the USA) the Code of Federal Regulations and, in particular, Volume II Parts 100–199 which includes lists of approved additives in packaging such as plasticisers. Adler et al. A combination of regulatory and economic pressures drives the use of clean production technologies and best practices by packaging manufacturers. These processes may involve specific materials, plastics and barrier materials, such as aluminium foil, to extend their packaging applications and the shelf life of the products they contain. Many landfills, such as Fresh Kills in New York City, were not lined. 2006) compared two types of containers that have been designed and are being used to pack and ship fresh fruits and vegetables: reusable plastic containers (RPCs) and single-use display-ready paper corrugated trays (DRCs). A sensitivity analysis indicated that high-energy demands for PLA production could tip the balance in favour of PS drinking cups. In the DRC system, a container is manufactured for each trip to retail. Growing concerns of consumers, brand owners and governments to address supply chain concerns regarding pack integrity, brand authenticity/product provenance, food safety, waste, product quality, counterfeiting, product tampering and theft. This would also be favorable for water and landscape quality and biodiversity by reducing nutrient loads (Bouma et al., 2008). In 1991, the EU nitrate guideline was introduced, limiting N applications in manure to 170 kg ha−1 with the objective to reduce the nitrate content of groundwater. An Australian study concluded that recycling materials rather than using virgin materials and sending waste to landfill, achieves an energy saving of up to 93% (see Table 10.1). This has important implications for packaging designers. In the United States, the Food and Drug Administration (FDA) governs the use of recycled resins in food, drug and cosmetic packaging. Do not recycle’. Cities send these materials forth into the world and receive them back as they move through closed-loop cycles. Oxo-biodegradable polymers (often called ‘degradable polymers’) combine a conventional polymer such as polyethylene with a controlled degradation master-batch additive. Despite some misconceptions, an environmentally sound production plan doesn’t have to be a more expensive option. Communication was hampered by unclear and nontransparent environmental rules and regulations. Cradle to Cradle ® Design transmits the principle “Quality equal Quantity” to industrial systems. 103–104, italics in original). The model confirmed the nonlinear nature of the relationship between recycling rates and primary pulp requirements. Clarity about the goals of recycling should make it possible to set priorities, selecting areas where the greatest quantities of useful materials can be conserved or recovered, and the greatest environmental gains achieved, at the lowest cost. The injection legislation of 1994 (box 3) was, however, based on K5 research at the time (box 2: Huijsmans et al., 2001).
