EnviroStraw’s revegetation solutions deliver significant water efficiencies and cost savings

Water efficiency is critical on construction and mine sites, especially in remote and dry areas of Australia, and EnviroStraw has proven revegetation solutions that transform any soils using up to 40% less water than conventional products!

Water efficiency and your project

Targeting the best possible Water Use Efficiency (WUE) result on any project is a key goal for project designers and construction managers on large sites across Australia. But our harsh climate can make this very difficult to achieve as we face changing climatic conditions and longer periods of hot and dry weather.

There is also the impact on the environment to consider especially if water is needed to be withdrawn from local rivers and streams for a revegetation project. Costs increase while the surrounding ecology and aquatic wildlife can suffer.

Water savings with EnviroStraw

There are many benefits to using EnviroStraw’s innovative products and programs to quickly and sustainably revegetate any site. But one of the standout features of EnviroStraw’s soil science technology is the water savings.

This high level of water efficiency results in significant cost savings by reducing the need for ongoing maintenance and watering and lowering the risk of needing any expensive reworks. These water savings are also beneficial for the environment not only because you’re using less of this precious resource, but a reduced reliance on watering systems also means that there’s less degradation of the soil and greater erosion control.

World-first technology that works

Working with Australia’s leading soil scientists, EnviroStraw has developed products and programs that are proven and tested to use significantly less water during the application process compared to our competitors. Our low water usage solutions using our Hydromulch products can be tailored to the specific needs of each site.

We’ve also developed non-watering options that are delivered by including our EnviroBond Polymer which is a unique, high performance liquid soil binder. Then you can just sit back and wait for Mother Nature to provide the water for free which could save hundreds of thousands of dollars in watering costs on a large scale project! Here we explain how these ground-breaking solutions work.

Low water usage

EnviroStraw’s BioGrowth™ is a world first system that blends fertilisers and a long term control release nitrogen source with 22 specially selected microbes. This works to naturally and rapidly build up the levels of carbon and nutrients in the soil, increasing microbial activity which in turn enables an optimum level of water infiltration and moisture retention.

When combined with EnviroStraw’s range of specially designed Hydromulch products and applied to a site, the results are astounding. EnviroStraw Hydromulch products require up to 40% less water than conventional mulch products. As an example, using EnviroStraw Hydromulch will save 42,000 litres of water per hectare compared to using a standard sugar cane paper blend hydromulch product. And you’ll save more than 30,000 litres of water by using EnviroStraw Hydromulch compared to using a conventional wood fibre mulch.

Using the EnviroStraw Hydromulch programs substantially reduces the cost of running water trucks on site to fill the hydromulching machinery. This improves on site efficiencies with each tank of hydromulch covering more area per tank load compared to conventional products. It all adds up to significant cost and water savings for site managers.

Non-watering option

Often revegetation projects can be high maintenance requiring ongoing watering systems which can be very expensive when a site is located in a hot, dry climate. Trying to keep up with the watering requirements of the establishing vegetation and prevent it dying off can be an impossible task.

EnviroStraw has a non-watering option that’s easy to implement and costs cents on the dollar compared to a traditional watering program. Our special liquid soil binder, EnviroBond Polymer, creates a 3D honeycomb shaped matrix in the topsoil layers which can penetrate and bind any soil type, even sand. This protects nutrients and seeds and retains water, holding the soil and EnviroStraw Hydromulch layer in place for up to 12 months or longer while waiting for natural rain events to occur.

  • Some of the benefits of EnviroBond Polymer include:
  • No water required via water trucks saving you money
  • Natural rain events germinate the grass seed free of charge
  • Improved stability of the Hydromulch layer
  • Significantly reduces the risk of erosion
  • Protects the grass seed and holds it in place
  • Enhances germination
  • Improves water penetration into the soil
  • Improves the water holding capacity of the soil

Big ideas, world class results, proudly Australian made

The EnviroStraw difference – the benefits of Australian made revegetation solutions

Australian grown ingenuity and tenacity is proving its worth for those needing to revegetate commercial and civil sites. EnviroStraw had humble beginnings, but a big idea and a passion for doing things differently has seen it grow into an Australian success story proving you can find world-leading, proven revegetation solutions right here at home.

From humble beginnings to world-class provider

EnviroStraw was founded after the devastating Queensland floods of 2011 with a driving ambition to use only Australian renewable resources and support local jobs. That focus on providing high quality revegetation products created right here in Australia has paid off.

EnviroStraw is now the in-demand provider of advanced revegetation solutions for mine sites, commercial developments and infrastructure projects. Our products and innovative programs transform highly disturbed soils into lush, green grass quickly and cost-effectively all while supporting Australian farmers, workers and communities.

A challenging road to success

It wasn’t all smooth sailing to get to where we are today but those challenges have taught us valuable lessons and helped us find solutions that are setting a new standard in our industry.

The first obstacle was the long search for the right mechanically and thermally-processed fibre material to make our Hydromulch. The easy route would have been to just import product from overseas but we stuck to our commitment to Australian-made. We found the perfect straw cubes in Yarrawonga in rural Victoria, working hard to hone the production process with our manufacturing partner.

After much trial and error with the packaging for our products, we also decided to invest in our own baling equipment. This has meant we deliver a consistent package every time to our clients eliminating any contamination issues.

When it came to the binders and tackifiers that hold our Hydromulch products on the ground, traditional methods weren’t working so we designed our own. We tried countless formulas until we came up with the ideal binder and now our Hydromulch stays where it is sprayed.

This determination to find Australian-grown solutions has resulted in EnviroStraw’s range of Hydromulch products and innovative programs meeting and exceeding world-class standards. We regularly send shipments to international buyers in China and Papua New Guinea as well as our domestic clients.

The benefits of supporting Australian-made

In an industry which is seeing increased competition from international products, EnviroStraw stands out as a wholly Australian-owned and operated leader in the revegetation field. We employ Australian workers, we only use Australian renewable resources bought from Aussie farmers and our products are made in rural Victoria.

We all know the trials Aussie farmers are facing whether it’s severe drought, bushfires or floods. Being able to back farmers at such a challenging time is incredibly important to the team at EnviroStraw. It makes us proud to know that we buy the crops of Aussie farmers and that by manufacturing our products in rural Victoria we’re in turn supporting the local community.

Home-grown expertise that works

By working with an Australian-owned company, our clients are supporting Australian jobs and the use of Australian renewable resources. That means little however unless your product really works. And EnviroStraw’s range of revegetation solutions are proven to achieve superior results even in the extremely challenging Australian environment.

It’s incredibly satisfying to watch grass grow in what seemed like impossible conditions. EnviroStraw teamed up with one of Australia’s leading microbiologists and soil scientists to set this new standard in revegetation. Some examples of this include:

  • our BioGrowth system which rehabilitates highly disturbed and damaged soils with minimum effort and cost;
  • our non-watering program which saves project owners substantial sums of money; and
  • our GeoSpray product which stops erosion in its tracks for extended periods of time.
