OCS Environmental We have the most robust and versatile lines of covers available in the industry.

Alternative Daily Cover

August 4th, 2013 by

OCS Environmental are the exclusive distributors in Australia and New Zealand for New Waste Concepts Inc’s (NWCI) ConCover and ProGuard range of alternative daily cover products and proprietary spray machines.

Despite what you may have heard, or what others may have told you – no single cover can solve every problem. Depending upon your unique needs, and, more specifically, the unique nature of your landfill, we have the most robust and versatile lines of alternate daily covers available in the industry – geared for your specific applications and needs. 

All of our products are constructed of non-toxic, biodegradable, and environmentally friendly materials. Unlike cement based (cementaceous) covers, which contain hazardous and carcinogenic materials, our covers are slurry-based – made primarily of food grade polymers and clays. 

Our alternate daily covers are also material neutral – giving them distinct advantages when used as delivery methods for other products. They won’t interact or cause unwanted or unintended consequences with other materials or in your leachate collection systems. 

We strongly believe in developing products for specific application situations – but always being flexible enough to integrate with our other products.

All covers are not created equal! So…What type of covers are right for you?


Daily Covers – ProGuard IIB and TopGuard

The working face of all putrescible, dry waste and hazardous landfills must include a daily cover for preventing debris from blowing, minimizing pests & fire threats and for controlling odours. Even construction and demolition debris landfills are required to cover daily.For over 25 years New Waste Concepts has helped its clients meet the legislative requirements and our ProGuard line of ADC’s (Alternative Daily Covers) are specifically designed to meet these regulations.

Intermediate Covers – ConCover SW

When areas of the previous days active working face of a landfill won’t be covered with new waste for an extended period of time, intermediate covers are called for. These covers are used when the length of inactivity ranges from anywhere from 7 to 60 days (depending on your operating license), and need to be durable enough to survive through wind and rain.Unlike other manufacturers, New Waste Concepts has actually developed a cover specifically made for intermediate use. Its material neutral construction is flexible enough to be used in combination with seed and growth stimulants – yet durable enough to protect and last between 8-12 months.
