The project that has been implemented here is beneficial not only for the company but also for our customers.

Venture showcases one of the winning ideas – a method for collecting, cleaning and recycling rainwater for use in equipment processing activities, submitted by the team at WWL’s Manzanillo Terminal in Panama.

“When it comes to sustainability, the Panama processing and distribution hub is like no other in Latin America,” says Sergio Villicana, Manager of the Panama Equipment Processing Centre (EPC).

“We already have skylights and special ceilings to help us reduce electricity consumption. In addition, the positioning of the buildings and windows helps limit air conditioning use, while the materials in the buildings are recyclable and sustainable.”

In Panama, potable water is a valuable resource and, at the Manzanillo EPC,a high volume is needed to wash and prepare clean cargo. Over the course of the 2011 Castor Green Challenge, team members worked closely together to develop a rainwater capturing and recycling system. They calculated that, with an effective system in place,they could reduce the use of running water to just five percent – representing the plant’s drinking water requirements – while all remaining activities, including the pressure washing of equipment, toilet flushing and general cleaning, could be covered using rainwater.

In Manzanillo, it rains for nine months a year. Rainwater has a number of advantageous features. On the one hand, it is extremely clean compared with many other sources of fresh water. On the other, it is an essential resource that is completely free and only requires a very simple solution for collection, storage and distribution.

“As Panama is an area with a rainy climate, we saw an opportunity,” explains Julio Moreno, Lead Technician at the Manzanillo EPC. “We already had the rainwater – and it’s free – we just needed to find a way of collecting, storing and re-using it.”

A relatively simple solution has been created, which is able to collect and store the rainwater, as well as covering, filtering and pumping it. The mechanism also makes a switch back to mains water possible, if necessary, while polluted or dirty water can be discarded. It is estimated that the investment will pay for itself in less than two years, given the substantial reduction in water costs for the facility.

“The project that has been implemented here is beneficial not only for the company but also for our customers,” adds Moreno. “It enables us to optimise our processes, while supporting our environmental goals at the same time.”

“We used a lot of natural resources to create the EPC,” comments Mary Carmen de Mendoza, Panama Operations Manager. “However, our people remain our most valuable resource. It’s thanks to their ideas and creativity that we can deliver value to our customers every day.”

Castor Green Competition
The Castor Green Competition, which also takes place in 2012, has been designed to inspire the creative minds of WWL’s employees to help WWL achieve its zero-emission environmental targets, exemplified by the Castor Green Terminal concept. The Castor Green Competition 2011 generated 116 new ideas, submitted by 250 WWL employees at nine sites, from which five winners were selected. The winning ideas included a power generator using wind turbines, a solar-powered charge solution, an innovative rain-capturing mechanism and a “simple”
