How does sugarcane capture carbon and reduce your carbon footprint?
Plants take in carbon dioxide from the atmosphere through small pores in their leaves. They need carbon dioxide for photosynthesis, which leads to the production of sugars, and eventually more complex molecules for use by the plant in growth and metabolism. The carbon dioxide captured during the sugarcane cultivation process (from sugarcane growth until its production) remains stored during the plastic's entire life cycle (as long as it is not incinerated). Every kg of sugar plastic captures and stores approximately 2kg of CO2 from the atmosphere (6).
Are sugar plastic bottles 100% kerbside recyclable?
Yes. Sugarcane-based HDPE (high-density polyethylene) is physically and chemically identical to traditional petrochemical plastic. This means it can be recycled in the same chain used for recycling traditional (#2) from petrochemical sources (unlike other bio-based plastics which can’t be recycled this way). Across the ecostore range we’re now incorporating recycled plastic into our bottles, in a 50:50 mix of sugar plastic and recycled plastic – which is also 100% kerbside recyclable and refillable.
Is it biodegradable?
No, it is not biodegradable or compostable. Current technology requires biodegradable plastic to go through a commercial composting facility. This is not readily available in Australasia, so as a result biodegradable plastic ends up contaminating recycling streams or ends up in landfill where it is slow to biodegrade so less than ideal. Like plastics made from petrochemicals, sugar plastic is a recyclable material and in fact can be recycled normally using the facilities we already have. If our sugar plastic bottles did biodegrade or is incinerated, the captured carbon dioxide would be released back to the atmosphere and it would then be carbon neutral. The fact that it is recyclable is a benefit as it reduces carbon emissions.
Why is sugar plastic so important?
Sugar plastic reduces the need for fossil fuels. Polyethylene (plastic) is conventionally produced from raw materials such as oil or natural gas, which are non-renewable, as they are derived from pre-historic fossils and are no longer readily available once used. The extraction processes used to obtain fossil fuels are associated with many negative environmental impacts including risks of oil spills, destruction of wide areas of land and resulting ecological imbalance.
Are there additional benefits from using sugar plastic?
Processing facilities that make the sugarcane ethanol operate almost exclusively on renewable energy that comes from the sugarcane by-products. Sugarcane bagasse, a waste product from the crushing process, is often used to generate power to supply the entire ethanol production process, which makes it energy self-sufficient. Any surplus power is sent to the grid, adding energy to Brazil's energy matrix. The production process of sugar plastic uses over 70% less fossil fuels than traditional petroleum-based (HDPE) plastic.
What % of the bottle comes from sugarcane?
92% of each bottle is made from renewable sugar plastic (7). Sugar plastic is made only from sugarcane (ethanol) suppliers certified by Bonsucro who are a global non-profit organisation dedicated to reducing the environmental and social impacts of sugarcane production while recognising the need for economic viability. Note: our bulk containers (4.5kg, 5kg, 5L and 20L) are made from standard HDPE plastic.
How many of your bottles contain sugar plastic?
All of our bottles now contain a mix of recycled and sugar plastic. This currently, excludes our caps, lip balm tubes and our bulk containers which are made from standard HDPE plastic. We are working on changing these as well, but first wanted to focus on the majority of our packaging to make the biggest difference.
Is there any noticeable difference in the plastic?
No, you won’t notice the difference in terms of look, texture or strength, as sugar plastic is physically and chemically identical to traditional petrochemical plastic. The same performance you love and expect, but in a more sustainable bottle.
Is the use of pesticides and fungicides a regular practice on sugarcane plantations?
The main diseases that threaten the plants are treated using biological controls and genetic improvement programs. This way, the use of pesticides on sugarcane plantations in Brazil is low and the use of fungicides is practically non-existent.
Do you use genetically modified sugarcane crops?
No, genetically modified sugarcane is not sold in Brazil, which is where our sugarcane is grown. This is currently restricted to cotton, corn and soybean only.
Does sugarcane cultivation use only rainwater?
Sugarcane in Brazil is practically not irrigated. Water needs, in the agricultural phase, are resolved naturally by the rainfall of the producing regions, mainly the center-south of Brazil, and is complemented by the application of vinasse, a co-product of ethanol production that is rich in water and organic nutrients, in a process called fertigation.
Where does the sugarcane come from?
90% of sugarcane cultivation and harvesting in Brazil is concentrated in the South-Central region of Brazil, which is located more than 2500km from the Amazon rainforest. The expansion of planted areas is regulated by the Sugarcane Agro-ecological Zoning Policy, a regulatory framework implemented in 2009 by the federal government that prohibits planting in areas with high levels of biodiversity, including among other areas, the Amazon, Pantanal biomes, indigenous lands and environmentally protected lands.
Does the growing consumption of sugarcane ethanol for sugarcane plastic production have any impact on food production?
Today Brazil has 330 million hectares of arable land, only 1.4% of all arable land in Brazil is dedicated to ethanol production, and the consumption of ethanol for the production of sugarcane plastic represents about 1.7% of the total production of ethanol, or 0.02% of Brazil's arable land (8). The existence of available land, combined with a possible intensification of livestock production, makes Brazil a country with room for expansion of agriculture. The use of land for the production of products other than food, even in a very optimistic scenario for the growth of the production of chemicals from renewable sources, should continue representing a small percentage of the total land available. The government has accepted a proposal to limit the expansion of sugarcane cultivation to 7.5% of Brazil’s landmass (65.7 million hectares). This proposal took into account the environmental, economic and social aspects in order to coordinate the sustainable expansion of sugarcane cultivation.
How many tons of sugar plastic is produced per hectare of sugarcane?
53.5 hectares of land are required to produce a year’s supply of sugar plastic for ecostore; this is accounts for 0.00002% of Brazil’s total arable land. In one hectare, approximately 82.5 tons of sugarcane is produced, which can produce 7,200 litres of ethanol. This volume of ethanol produces three tons of ethylene, generating around three tons of sugar plastic.
Is sugarcane cultivated in a socially responsible and sustainable manner?
Sugarcane cultivation is conducted in accordance with Brazilian law and the rules and labour conditions established by the International Labour Organization (ILO) that should be followed by all employers, which are subject to regular inspections by the government. Our sugarcane-based HDPE supplier also has implemented a Code of Conduct for Ethanol Suppliers that is part of the “National Commitment to Social Assistance” program, which ascribes rights to workers and ensures them a better quality of life. The code of conduct covers 5 pillars – reduction of cane burning, conserving biodiversity, good environmental practises, respect for human rights and life cycle assessment. This is guaranteed by a third party auditing programme.
Why is sugarcane burned and will this practice continue?
Traditionally, sugarcane is burnt before manual harvesting, to make the activity of cutting sugarcane safer by burning its straw. The introduction of mechanical harvesting means sugarcane no longer needs to be burnt prior to harvesting which is great news for reducing CO2 emissions. The deadline for the end of burning is provided in Brazilian Law. Additionally, in 2007 the Protocolo Agroindustrial do Estado de São Paulo (Agroindustrial Protocol of the State of São Paulo) was voluntarily launched, which set more restrictive targets than the law. The mills signing this protocol commit to the anticipation of the deadlines to quit burning in legislation. In mechanized areas, the term is from 2014 to 2021, while in areas considered non-mechanized by current technology, the deadline is 2017 to 2031. In 2009, over 95% of all ethanol produced in the state of São Paulo, the largest Brazilian producer state, was produced in mills that signed the Protocol.
Why do you use plastic bottles?
Plastic packaging is one of the world’s big problems. It’s also a real challenge for us here at ecostore: how to make our packaging safe, stylish and easy to use while also being sustainable. We’ve always opted for the best options available at the time – even when that’s meant making difficult choices like using plastic, as stepping stones towards more sustainable packaging solutions. Our bottles are made from a mix of renewable sugar plastic and recycled plastic, which is 100% recyclable, and a much more sustainable alternative to virgin petroleum-based plastic.
Why don’t you use glass packaging?
We don’t use glass bottles for a few reasons, including that it is heavy to ship and generally requires extra packaging to enable it to travel safely – all these factors increase its carbon footprint. Safety of consumers is also an important consideration for us, and there is a risk of glass chipping and breaking. We believe our sugarcane plastic is the most responsible packaging option we can choose currently to store our product. We also supply bulk products and refill stations to help reduce further waste. As brands embrace sustainable business practice we hope the use of bio plastics will become the norm. As early adopters of the renewable plastics innovation (starting in 2014), we are proud to be an inspiration to all brands/consumers and show leadership in ethical business.
Can recycled plastics be recycled over and over?
There’s often a finite number of times materials can be recycled before they have to go to landfill. The polymers that make up the different types of plastic can get cross-contaminated, or absorb particles from the substance they contain. Recyclable plastics can usually be recycled 7-9 times, while aluminium, glass and steel can be recycled forever as these materials don’t lose integrity during recycling.
