The Green Revolution: Sharing leading the way

In a world grappling with pressing environmental challenges, the call for sustainable solutions has never been more urgent. One such solution gaining rapid momentum is the sharing economy, a model that not only promotes resource efficiency but also leads us on the path towards a greener planet. The sharing economy actively encourages the sharing, renting, and borrowing of goods, services, and spaces, fostering a sense of community while simultaneously minimizing our ecological footprint. In this article, we explore why sharing and the sharing economy are indispensable for the planet and how they can shape a more sustainable future.

 

Resource Conservation

At the heart of the sharing economy lies its ability to optimize resource utilization. Sharing goods ensures that their lifespan is maximized, consequently reducing the need for overproduction. A prime example is the success of car-sharing services. Instead of each individual owning a car that remains idle for most of its life, car-sharing platforms enable multiple people to use the same vehicle, thus decreasing the number of cars on the road and the associated resource consumption.

Reduced Waste

In a world plagued by excessive waste production, the sharing economy provides a remedy by discouraging unnecessary consumption. Sharing platforms offer individuals access to items they need temporarily, effectively reducing the demand for single-use products. Tools, appliances, or clothing can be shared within a community, eliminating the need for every individual to buy these items individually. This practice significantly reduces waste generation and lessens the environmental impact linked to manufacturing and disposal.

Energy Efficiency

The sharing economy also champions energy efficiency by encouraging the utilization of existing resources rather than the creation of new ones. Home-sharing platforms, for instance, enable homeowners to rent out their unused spaces, be it an extra room or an entire house. By making use of existing housing infrastructure, we optimise energy consumption in contrast to constructing new buildings. Furthermore, these platforms incentivise homeowners to invest in energy-efficient practices and technologies, such as renewable energy systems or energy-saving appliances, ultimately reducing carbon emissions.

Sustainable Lifestyles

Embracing the sharing economy fosters a shift in mindset from ownership to access. Instead of relentlessly pursuing possession, people begin to prioritize experiences and the efficient use of resources. This shift in consumer behavior can lead to a more sustainable lifestyle. When individuals recognize the value of sharing and collaboration, they become more conscious of their consumption patterns, opting for sustainable choices that benefit the planet.

Strengthened Communities

The sharing economy has a profound social impact as it brings people together and builds stronger communities. Sharing platforms often connect individuals living in close proximity, facilitating interaction and trust-building. When people collaborate, share resources, and support one another, a sense of belonging and shared responsibility develops. These communities often extend beyond the digital realm, fostering increased social cohesion and support networks.

Innovation and Entrepreneurship

The sharing economy has opened up avenues for innovation and entrepreneurship, particularly in sustainable sectors. It has given rise to new businesses and start-ups focused on sharing services, renewable energy, sustainable transportation, and circular economy practices. These ventures have the potential to create new jobs, drive economic growth, and contribute to a more sustainable future.

Leading the Way

Companies like RentMy enable people to “share” everything they own with others in their community. From paddleboards to canoes, DIY tools to garden equipment, musical instruments to cooking appliances, you can earn money from all the items that are just sitting around.

Tentshare and Camptoo do the same but for niched products like tents, camping equipment, and camper vans, allowing people to experience an adventure weekend without the significant upfront costs for all the equipment.

Then there’s Bike Club, a subscription service for bicycles that allows your child to upgrade each time they outgrow their ride. For adults, there’s Spinlister, which connects people who want to ride bikes with bike owners all over the world.

 

Next Steps

Without a doubt, the sharing economy is here to stay, largely because the benefits it offers are immense. It’s a sustainable choice, reducing the demand for brand-new products. It also promotes community, particularly those with a local focus. It can save and earn you money, with peer-to-peer lending offering an alternative to buying expensive equipment outright and also providing additional income to those renting out their assets.

But what truly drives this fast-growing economy is trust.

This is what allows someone to take a car ride from a stranger or rent a room in a house from someone they’ve never met.

 

How Do You Build Trust?

The article, aptly titled “The Decline of Serial Killers and the Rise of the Sharing Economy,” suggests that the internet has played a significant role in increasing trust between strangers.

Thanks to the fact that nearly all of us have a virtual identity these days, it’s challenging to go completely under the radar, reducing our fear of strangers.

This means we are more willing to engage with those we don’t know, seeing “strangers” as “peers.”

Businesses operating within the sharing economy are also employing various tactics to build upon this trust. For example, we encourage users to upload profile photos and write detailed profile descriptions that help identify them on a personal level.

We have also addressed concerns about the risk of damage. This has been a vital part of the development of RentMy. We provide extensive insurance protection for all those on our platform, allowing lenders to loan their items out risk-free, knowing that we will cover any damage or loss.

 

Final Thoughts

In a world increasingly aware of the environmental challenges we face, the sharing economy has emerged as a beacon of hope, leading the way towards a more sustainable future. It champions resource conservation, reduces waste, promotes energy efficiency, and encourages sustainable lifestyles. Moreover, it fosters stronger communities, fuels innovation and entrepreneurship, and ultimately drives positive change in our society.

Companies like RentMy, Tentshare, and Bike Club exemplify how individuals and businesses can play a pivotal role in this transformative movement. The sharing economy is not only here to stay but also set to thrive, offering a sustainable, community-driven, and financially rewarding path forward.

But, as we embrace the sharing economy, we must recognise that trust is its cornerstone. The internet has been a key enabler, reducing our fear of strangers and turning them into peers. Building trust involves transparency, identity verification, and addressing concerns, such as the risk of damage. At RentMy, we take these concerns seriously, offering comprehensive insurance protection to assure both sharers and renters.

Trust is the bridge that allows us to share with one another, and as we continue down this path, it’s a bridge that will only strengthen and lead us towards a greener, more interconnected world. So, as we take that car ride from a stranger or rent a room from someone we’ve never met, we are not just participating in the sharing economy; we are actively shaping a more sustainable, connected, and trust-driven future for all.

Honeywell & Recipharm to reduce greenhouse gas emissions

Honeywell & Recipharm to reduce greenhouse gas emissions

Honeywell and Recipharm have partnered to utilize technology to reduce greenhouse gas emissions in respiratory care and to lessen its environmental impact
Technology giant Honeywell has announced a commercial partnership with global contract development and manufacturing organisation (CDMO) Recipharm to develop pressurised metered dose inhalers (pMDIs) that use Honeywell’s near-zero global warming potential (GWP) propellant.

Globally, as many as 646 million people suffer from either chronic obstructive pulmonary disease or asthma, both of which are often treated using pMDIs. However, pMDIs have a high global warming potential due to the use of hydrofluoroalkanes.

To counter this, Honeywell Solstice® Air is an alternative technology, proven to reduce the greenhouse gas (GHG) emissions pMDIs by up to 99.9%, in comparison to current inhaler propellants.

“As the first CDMO to partner with Honeywell for the use of Solstice Air, this collaboration significantly accelerates and simplifies our customers’ pathway to develop the next generation of low greenhouse gas pMDIs,” said Chris Hirst, president of Recipharm’s Advanced Delivery Systems business unit. “Our collaboration is supported by Recipharm’s investment in manufacturing with HFO-1234ze(E) cGMP at our Holmes Chapel, United Kingdom site, and the further development of the Bespak® valve range to ensure the required product performance.”

Honeywell: Using technology to create sustainable change

The business has invested more than US$1bn in research, development and new capacity for its Solstice technology. This technology can be used to improve the sustainability credentials of applications in refrigerants, blowing agents, aerosols and solvents, to name a few.

Consequently, the Honeywell Solstice technology has helped avoid the potential release of more than 326 million metric tonnes of carbon dioxide into the atmosphere. This is approximately equal to the carbon emissions generated from 70 million gasoline-powered passenger vehicles each year.

“Honeywell is making great strides to offer patients who rely on pMDIs a lower greenhouse gas solution to meet their medical needs,” said Laura Reinhard, Vice President and General Manager of Honeywell Foam and Industrial Products. “Through our collaboration with Recipharm, the increased use of near-zero GWP propellant used in pMDIs will help reduce the environmental impact of the life-saving medical treatments patients need, without sacrificing performance.”

Climate explained: Why does geothermal electricity count as renewable?

Climate explained: Why does geothermal electricity count as renewable?

Geothermal electricity produces emissions but is categorised with wind and solar power as a renewable source of power. Why? Can we reduce the emissions geothermal plants produce?

Geothermal resources occur where magma has come up through the Earth’s crust at some point in the distant past and created large reservoirs of hot rock and water.

 In New Zealand, the Taupo Volcanic Zone has 23 known geothermal reservoirs. Seven of these are currently used to generate more than 15 per cent of New Zealand’s electricity supply.

Continuous but finite energy source

The geothermal reservoirs are vast in both size and stored energy. For example, the Ngatamariki reservoir extends over seven square kilometres and is more than a kilometre thick.

The geothermal resource is more consistent than hydro, solar and wind, as it doesn’t depend on the weather, but the geothermal heat in a reservoir is finite. Environment Waikato estimates that if the thermal energy in New Zealand were extracted to generate 420MW of electricity, the resource would likely last for 300 years. The current generation is more than twice this rate, so the reservoirs will last about half as long.

Geothermal energy is extracted by drilling up to 3km down into these hot zones of mineral-laden brine at 180-350 degrees Celsius. The engineering involves drilling a number of wells for extraction and re-injection of the brine, and the big pipes that connect the wells to the power plant.

The power plant converts the thermal energy into electricity using steam turbines. These plants generate nearly continuously and can last for more than 50 years.

Greenhouse gas emissions

The brine contains dissolved gases and minerals, depending on the minerals in the rocks the water was exposed to. Some of these are harmless, like silica which is basically sand. But some are toxic like stibnite, which is antimony and sulphur.

Some gases like carbon dioxide and methane are not poisonous, but are greenhouse gases. But some are toxic. For example, hydrogen sulfide gives geothermal features their distinctive smell. The carbon dioxide dissolved in geothermal brine normally comes from limestone, which is fossilised shells of sea creatures that lived millions of years ago.

The amount of greenhouse gas produced per kWh of electricity generated varies, depending on the reservoir characteristics. It is not well known until the wells are in production.

The New Zealand Geothermal Association reports the greenhouse gas emissions for power generation range from 21 grams CO2 equivalent per kWh to 341gCO2(equiv)/kWh. The average is 76gCO2(equiv)/kWh. For comparison, fossil fuel generation emissions range from 970 to 390gCO2(equiv)/kWh for coal and gas combined cycle plants.

The gases have to be removed from the brine to use it in the plant, so they are released to the atmosphere. The toxic gases are either diluted and released into the atmosphere, or scrubbed with other substances for disposal. The Mokai power plant supplies carbon dioxide to commercial growers who use it in glasshouses to increase the growth rate of vegetables.

 

Finding ways to use less energy

All energy-conversion systems can be made better by employing engineering expertise, investing in research and enforcing regulations, and through due diligence in the management of the waste products. All energy-conversion technology has costs and consequences. No energy resource should be thought of as unlimited or free unless we use very small quantities.

New Zealand is in a period of energy transition, with a goal of reducing greenhouse gas emissions to net zero by 2050. The production and use of coal is already in decline globally and oil and gas are expected to follow.

We tend to think about energy transition in terms of technologies to substitute “bad” energy with “green” energy. But the transition of how energy is produced and consumed will require a massively complex re-engineering of nearly everything.

The installed capacity for wind and solar has been growing over the past decade. In 2018, however, New Zealand consumption of electricity generated by wind and solar was 7.72PJ, while oil, diesel and LPG consumption was 283PJ and geothermal electricity was 27PJ. Another consideration is lifetime; wind turbines and solar panels need to be replaced at least three times during the lifetime of a geothermal power plant.

A successful energy transition will require much more R&D and due diligence on productsbuildings and lifestyles that need only about 10 per cent of the energy we use today. An energy transition to build sustainable future systems is not only possible, it is the only option.
